  • Influence of the South Asian High and Western Pacific Subtropical High Pressure Systems on the Risk of Heat Stroke in Japan
    Takehiro Morioka, Kenta Tamura, Tomonori Sato
    Atmosphere, 16, 6, 693, 693, MDPI AG, 08 Jun. 2025
    Scientific journal, Weather patterns substantially influence extreme weathers in Japan. Extreme high temperature events can cause serious health problems, including heat stroke. Therefore, understanding weather patterns, along with their impacts on human health, is critically important for developing effective public health measures. This study examines the impact of weather patterns on heat stroke risk, focusing on a two-tiered high-pressure system (DH: double high) consisting of a lower tropospheric western Pacific subtropical high (WPSH) and an overlapping upper tropospheric South Asian high (SAH), which is thought to cause high-temperature events in Japan. In this study, the self-organizing map technique was utilized to investigate the relationship between pressure patterns and the number of heat stroke patients in four populous cities. The study period covers July and August from 2008 to 2021. The results show that the average number of heat stroke patients in these cities is higher on DH days than on WPSH days in which SAH is absent. The probability of an extremely high daily number of heat stroke patients is more than twice as high on DH days compared to WPSH days. Notably, this result remains true even when WPSH and DH days are compared within the same air temperature range. This is attributable to the higher humidity and stronger solar radiation under DH conditions, which enhances the risk of heat stroke. Large-scale circulation anomalies similar to the Pacific–Japan teleconnection are found on DH days, suggesting that both high humidity and cloudless conditions are among the large-scale features controlled by this teleconnection. Early countermeasures to mitigate heat stroke risk, including advisories for outdoor activities, should be taken when DH-like weather patterns are predicted.
  • Different Atmospheric Circulation Patterns Associated With Heatwaves Over Northeastern Siberia in July and August
    Xiling Zhou, Tomonori Sato, Shixue Li
    International Journal of Climatology, Wiley, 15 Mar. 2025, [Peer-reviewed]
    Scientific journal, ABSTRACT

    Globally, heatwaves have become more frequent over recent decades. Summer Siberian heatwaves have received less attention, even though ecosystems are vulnerable to high temperatures. This study investigates and compares the atmospheric circulation patterns associated with northeastern Siberian heatwaves in July and August. The results suggest a strong teleconnection between eastern Europe and northeastern Siberia, similar to the British–Okhotsk Corridor pattern, along a strengthened polar jet when frequent heatwaves occur in July. However, this teleconnection is less clear in northeastern Siberia in August due to weak Rossby wave activity linked to the waveguide effect. Instead, the formation of northeastern Siberian heatwaves in August is related to abnormally low pressure over the Arctic, as supported by a linear baroclinic model experiment. Additionally, the abnormally high pressure over northeastern Siberia may influence weather in the northwestern Pacific. These findings enhance the current understanding of summer Siberian heatwaves, suggesting their connection to Arctic atmospheric circulation and their importance for subseasonal weather predictions in the northwestern Pacific.

  • Evaluating How Historical Climate Change Affected a Heavy Snowfall Event in Northern Japan in Mid‐December 2021 Using Two Pseudo Global Warming Methods
    K. Tamura, T. Sato
    Journal of Geophysical Research: Atmospheres, 129, 24, American Geophysical Union (AGU), 16 Dec. 2024, [Peer-reviewed], [Last author]
    Scientific journal, Abstract

    In mid‐December 2021, heavy snowfall occurred when an extratropical cyclone passed around Hokkaido, northern Japan. In this study, we investigated the contribution of historical climate change to the heavy snowfall event using large ensemble simulation data sets and two pseudo global warming (PGW) methods. We classified the large ensemble simulation data sets by the pressure pattern and identified the extratropical cyclone event. Composite analyses reveal that the development of the extratropical cyclone can be attributed to historical climate change. We ran the PGW method with the classified meteorological data as the input data and found that the development of the extratropical cyclone resulted in enhanced water vapor transport and intensified local convergence in the lower troposphere, causing heavy precipitation. We also found that oceanic warming made a minimal contribution to the precipitation in this event. These findings highlight the importance of considering historical changes in event‐specific synoptic‐scale atmospheric conditions when evaluating the contributions of climate change to extreme events.
  • Rare bird forecast: A combined approach using a long‐term dataset of an Arctic seabird and a numerical weather prediction model

    Ecology and Evolution, 14, 6, Wiley, 25 Jun. 2024
    Scientific journal, Abstract

    Wildlife observation is a popular activity, and sightings of rare or difficult‐to‐find animals are often highly desired. However, predicting the sighting probabilities of these animals is a challenge for many observers, and it may only be possible by limited experts with intimate knowledge and skills. To tackle this difficulty, we developed user‐friendly forecast systems of the daily observation probabilities of a rare Arctic seabird (Ross's Gull Rhodostethia rosea) in a coastal area in northern Japan. Using a dataset gathered during 16 successive winters, we applied a machine learning technique of self‐organizing maps and explored how days with gull sightings were related to the meteorological pressure patterns over the Sea of Okhotsk (Method A). We also built a regression model that explains the relationship between gull sightings and local‐scale environmental factors (Method B). We then applied these methods with the operational global numerical weather prediction model (a computer simulation application about the fluid dynamics of Earth's atmosphere) to forecast the daily observation probabilities of our target. Method A demonstrated a strong dependence of gull sightings on the 16 representative weather patterns and forecasted stepwise observation probabilities ranging from 0% to 85.7%. Method B also showed that the strength of the northerly wind and the advancement of the season explained gull sightings and forecasted continuous observation probabilities ranging from 0% to 95.5%. Applying these two methods with the operational global numerical weather prediction model successfully forecasted the varied observation probabilities of Ross's Gull from 1 to 5 days ahead from November to February. A 2‐year follow‐up observation also validated both forecast systems to be effective for successful observation, especially when both systems forecasted higher observation probabilities. The developed forecast systems would therefore allow cost‐effective animal observation and may facilitate a better experience for a variety of wildlife observers.

  • Impact of spring land-surface conditions over the Tibetan Plateau on the early summer Asian monsoon using an AGCM large ensemble
    Hiroshi G. Takahashi, Shiori Sugimoto, Tomonori Sato
    Climate Dynamics, Springer Science and Business Media LLC, 20 Jan. 2024
    Scientific journal, Abstract

    Influence of land-surface memory effects over the Tibetan Plateau on the Asian summer monsoon has long been studied, but not quantified because of the difficulty of extracting only these effects from observational data. This study examines the impact of spring land-surface conditions, including surface air temperature (SAT) and snow cover, over the Tibetan Plateau and its surrounding regions on the early stage of the Asian summer monsoon using large-ensemble experiments produced by an atmospheric global climate model (AGCM). The results show that the above-normal SAT over and around the Tibetan Plateau in May can enhance June monsoon circulation without the sea surface temperature (SST) forcing. The physical mechanism behind this involves warmed surface air over the plateau enhancing the north–south SAT gradient, leading to strengthening the Asian summer monsoon circulation and precipitation. Inter-ensemble correlation analysis indicated that SAT warming over the plateau is clearly associated with upper-tropospheric anti-cyclonic circulation anomalies in May. Also, although winter land-surface signals do not persist until late spring, SAT anomalies in March tend to persist until May, explaining 10–20% of the total SAT variance in May. Interestingly, the spring SAT impacts on June monsoon circulations vary interannually, indicating that the contribution of the land–atmosphere (L–A) coupling process to interannual monsoon variability differs from year to year. Active L–A coupling years tend to coincide with cooler SSTs with anomalous low-level divergence and upper-level convergence over and around the Maritime continent, implying that SST forcing is associated with the L–A coupling strength. Specifically, in May of the developing stage of monsoon circulation, the weak Walker circulation over the equatorial and northern Indian Ocean and undeveloped monsoon circulation are suitable for the L–A coupling to influence the development of the monsoon circulation effectively. However, the well-known oceanic events, such as El Ni$${\widetilde{n } }$$o, are found to be less connected with the interannual L–A coupling variations.

  • Interannual variation of the Warm Arctic–Cold Eurasia pattern modulated by Ural blocking and the North Atlantic Oscillation under changing sea ice conditions
    Xiling Zhou, Tomonori Sato, Shixue Li
    Progress in Earth and Planetary Science, 10, 1, Springer Science and Business Media LLC, 03 Oct. 2023, [Peer-reviewed]
    Scientific journal, Abstract

    Together with rapid Arctic warming and sea ice decline, especially over the Barents–Kara seas (BKS), extreme cold winters have occurred frequently in mid-latitudes, particularly in Central Eurasia. A pattern with two distinct winter temperature anomalies centered over the BKS and Central Eurasia is known as the Warm Arctic–Cold Eurasia (WACE) pattern. The impacts of sea ice loss over the BKS and internal atmospheric variability on past WACE formation remain under discussion mainly due to the large internal atmospheric variability in the mid-latitudes. This study analyzed a large-ensemble historical experiment prescribing observed sea ice condition to investigate the role of internal atmospheric variability in the observed interannual variation of the WACE pattern. Comparison of ensemble members suggests that internal atmospheric variability is important for regulating the magnitude of the WACE pattern. Besides the strong effect of local sea ice loss, winter temperature over the BKS increases due to warm advection driven by the Ural blocking and positive phase of the North Atlantic Oscillation. A decrease in winter temperature over Central Eurasia is mainly attributable to the cold advection enhanced by Ural blocking rather than the remote effect of sea ice decline over the BKS. Our study reveals the importance of internal atmospheric variability in elucidating the observed interannual variation of the WACE pattern.
  • East Asian summer rainfall stimulated by subseasonal Indian monsoonal heating
    Shixue Li, Tomonori Sato, Tetsu Nakamura, Wenkai Guo
    Nature Communications, 14, 1, Springer Science and Business Media LLC, 22 Sep. 2023, [Peer-reviewed]
    Scientific journal, Abstract

    The responses of the East Asian summer monsoon (EASM) to the Indian summer monsoon (ISM) have been the subject of extensive investigation. Nevertheless, it remains uncertain whether the ISM can serve as a predictor for the EASM. Here, on the basis of both observations and a large-ensemble climate model experiment, we show that the subseasonal variability of abnormal diabatic heating over India enhances precipitation over central East China, the Korean Peninsula, and southern Japan in June. ISM heating triggers Rossby wave propagation along the subtropical jet, promoting southerly winds over East Asia. The southerly winds helps steer anomalous mid-tropospheric warm advection and lower-tropospheric moisture advection toward East Asia, providing conditions preferential for rainband formation. Cluster analysis shows that, depending on jet structures, ISM heating can serve as a trigger as well as a reinforcer of the rainband.

    Scientific journal, Abstract

    The prediction skill for precipitation anomalies in late spring and summer months—a significant component of extreme climate events—has remained stubbornly low for years. This paper presents a new idea that utilizes information on boreal spring land surface temperature/subsurface temperature (LST/SUBT) anomalies over the Tibetan Plateau (TP) to improve prediction of subsequent summer droughts/floods over several regions over the world, East Asia and North America in particular. The work was performed in the framework of the GEWEX/LS4P Phase I (LS4P-I) experiment, which focused on whether the TP LST/SUBT provides an additional source for subseasonal-to-seasonal (S2S) predictability. The summer 2003, when there were severe drought/flood over the southern/northern part of the Yangtze River basin, respectively, has been selected as the focus case. With the newly developed LST/SUBT initialization method, the observed surface temperature anomaly over the TP has been partially produced by the LS4P-I model ensemble mean, and 8 hotspot regions in the world were identified where June precipitation is significantly associated with anomalies of May TP land temperature. Consideration of the TP LST/SUBT effect has produced about 25–50% of observed precipitation anomalies in most hotspot regions. The multiple models have shown more consistency in the hotspot regions along the Tibetan Plateau-Rocky Mountain Circumglobal (TRC) wave train. The mechanisms for the LST/SUBT effect on the 2003 drought over the southern part of the Yangtze River Basin are discussed. For comparison, the global SST effect has also been tested and 6 regions with significant SST effects were identified in the 2003 case, explaining about 25–50% of precipitation anomalies over most of these regions. This study suggests that the TP LST/SUBT effect is a first-order source of S2S precipitation predictability, and hence it is comparable to that of the SST effect. With the completion of the LS4P-I, the LS4P-II has been launched and the LS4P-II protocol is briefly presented.
  • Localized Strong Warming and Humidification Over Winter Japan Tied to Sea Ice Retreat

    Geophysical Research Letters, 50, 11, American Geophysical Union (AGU), 06 Jun. 2023, [Peer-reviewed]
    Scientific journal, Abstract

    East Asian winter weather has altered dramatically in response to progressing climate change. However, analysis of time‐averaged atmospheric fields might obscure climate change signals that could relate to specific types of events. This study aimed to detect climate change signals for various background atmospheric fields by applying classification to daily surface pressure patterns. We found a pronounced trend of increase in surface air temperature over Japan since the 1980s, stronger than the seasonal mean trend, when dominating cold air advection from the Sea of Okhotsk. This cold air was warmed and humidified by the retreat of sea ice in the Sea of Okhotsk. In contrast, the warming trend was mitigated when warm air advection was dominant. These results highlight the importance of daily background atmospheric conditions in amplifying and localizing the impact of regional climate change.

    Scientific journal, Abstract

    The Asian Precipitation Experiment (AsiaPEX) was initiated in 2019 to understand terrestrial precipitation over diverse hydroclimatological conditions for improved predictions, disaster reduction, and sustainable development across Asia under the framework of the Global Hydroclimatology Panel (GHP)/Global Energy and Water Exchanges (GEWEX). AsiaPEX is the successor to GEWEX Asian Monsoon Experiment (GAME, 1995-2005) and Monsoon Asian Hydro-Atmosphere Scientific Research and Prediction Initiative (MAHASRI, 2006-2016). While retaining the key objectives of the aforementioned projects, the scientific targets of AsiaPEX focus on land-atmosphere coupling and improvements to the predictability of the Asian hydroclimatological system. AsiaPEX was designed for both fine-scale hydroclimatological processes occurring at the land surface and the integrated Asian hydroclimatological system characterized by multiscale interactions. We adopt six approaches including observation, process studies, scale interactions, high-resolution hydrological modeling, field campaigns, and climate projection, which bridge gaps in research activities conducted in different regions. Collaboration with mesoscale and global modeling researchers is one of the core methods in AsiaPEX. We review these strategies based on the literature and our initial outcomes. These include the estimation and validation of high-resolution satellite precipitation, investigations of extreme rainfall mechanisms, field campaigns over the Maritime Continent and Tibetan Plateau, areas of significant impact on the entire AsiaPEX region, process studies on diurnal to interdecadal scale interactions, and evaluation of the predictabilities of climate models for long-term variabilities. We will conduct integrated observational and modeling initiative, the Asian Monsoon Year (AMY)-II around 2025-2028, whose strategies are the sub-regional observation platforms and integrated global analysis.

    Scientific journal, Abstract

    Subseasonal-to-seasonal (S2S) precipitation prediction in boreal spring and summer months, which contains a significant number of high-signal events, is scientifically challenging and prediction skill has remained poor for years. Tibetan Plateau (TP) spring observed surface ­temperatures show a lag correlation with summer precipitation in several remote regions, but current global land–atmosphere coupled models are unable to represent this behavior due to significant errors in producing observed TP surface temperatures. To address these issues, the Global Energy and Water Exchanges (GEWEX) program launched the “Impact of Initialized Land Temperature and Snowpack on Subseasonal-to-Seasonal Prediction” (LS4P) initiative as a community effort to test the impact of land temperature in high-mountain regions on S2S prediction by climate models: more than 40 institutions worldwide are participating in this project. After using an innovative new land state initialization approach based on observed surface 2-m temperature over the TP in the LS4P experiment, results from a multimodel ensemble provide evidence for a causal relationship in the observed association between the Plateau spring land temperature and summer precipitation over several regions across the world through teleconnections. The influence is underscored by an out-of-phase oscillation between the TP and Rocky Mountain surface temperatures. This study reveals for the first time that high-mountain land temperature could be a substantial source of S2S precipitation predictability, and its effect is probably as large as ocean surface temperature over global “hotspot” regions identified here; the ensemble means in some “hotspots” produce more than 40% of the observed anomalies. This LS4P approach should stimulate more follow-on explorations.
  • Enhanced Arctic moisture transport toward Siberia in autumn revealed by tagged moisture transport model experiment

    npj Climate and Atmospheric Science, 5, 1, Springer Science and Business Media LLC, 24 Nov. 2022, [Peer-reviewed]
    Scientific journal, Abstract

    Rapid Arctic warming has altered the regional hydrological cycle through reduction in Arctic sea ice. Observational and modeling efforts provided evidence that the enhanced evaporation from the Arctic Ocean could increase snowfall over high latitude terrestrial zones. However, questions remain regarding the amount of equatorward moisture transport and its change over the decadal timescale. Here we show that the transport of atmospheric moisture to Siberia that originated from Arctic Ocean evaporation has increased significantly in autumn to early winter during 1981–2019 when substantial sea ice retreat was observed. The enhanced Arctic moisture content is found in western Siberia in September, consistent with the observed increase in snow cover investigated in earlier studies. Meanwhile, the annual maximum daily amount of Arctic moisture shows a sharp increase in eastern Siberia during October–December associated with cyclonic activities along coastal regions. Our results suggest the importance of monitoring equatorward moisture transport during snow accumulation seasons because it could enhance local snowstorms as evaporation from the Arctic Ocean increases in the near future.
  • Influence of convective processes on weather research and forecasting model precipitation biases over East Asia
    Shiori Sugimoto, Yongkang Xue, Tomonori Sato, Hiroshi G. Takahashi
    Climate Dynamics, Springer Science and Business Media LLC, 21 Nov. 2022, [Peer-reviewed]
    Scientific journal, Abstract

    Dynamical downscaling with a 20 km horizontal resolution was undertaken over East Asia for the period May–August in 1991–2015 using the Weather Research and Forecasting (WRF) model with Grell-3D ensemble cumulus parameterization as a product of the Impact of Initialized Land Temperature and Snowpack on Sub-Seasonal to Seasonal Prediction (LS4P) program. Simulated climatological precipitation biases were investigated over land during June when heavy precipitation occurred. Simulations underestimated precipitation along the Meiyu/Baiu rainband, while overestimating it farther north. Dry and wet biases expanded to south and north of the Yangtze River in China, respectively, marking years with poor precipitation simulations. Model biases in synoptic-scale circulation patterns indicate a weakened clockwise circulation over the western North Pacific in the model due to active convection there, and suppressed northward moisture transport to the Meiyu/Baiu rainband. Moisture convergence was slightly enhanced over central China due to an apparent anticyclonic circulation bias over northern China. In years with large biases, positive feedback between reduced moisture inflow and inactive convection occurred over southern China, while moisture transport to central China intensified on regional scales, with amplification of dry and wet biases over China. The Kain–Fritch scheme was used to test the influence of cumulus parameterization, improving the dry bias over southern China due to the modification of synoptic-scale circulation patterns in the lower troposphere. However, precipitation was further overestimated over central China, with the accuracy of precipitation distribution deteriorating.

    English, Scientific journal, AbstractThe intensity of extreme precipitation has been projected to increase with increasing air temperature according to the thermodynamic Clausius–Clapeyron (C-C) relation. Over the last decade, observational studies have succeeded in demonstrating the scaling relationship between extreme precipitation and temperature to understand the projected changes. In mid-latitude coastal regions, intense precipitation is strongly influenced by synoptic patterns and a particular characteristic is the long-lasting heavy precipitation driven by abundant moisture transport. However, the effect of synoptic patterns on the scaling relationship remains unclear. Here we conduct an event-based analysis using long-term historical records in Japan, to distinguish extreme precipitation arising from different synoptic patterns. We find that event peak intensity increases more sharply in persistent precipitation events, which lasted more than 10 h, sustained by atmospheric river-like circulation patterns. The long duration-accumulated precipitation extremes also increase with temperature at a rate considerably above the C-C rate at higher temperatures. Our result suggests that long-lasting precipitation events respond more to warming compared with short-duration events. This greatly increases the risks of future floods and landslides in the mid-latitude coastal regions.

  • Influence of Terrestrial Precipitation on the Variability of Extreme Sea Levels along the Coast of Bangladesh

    Scientific journal, The coastal area of Bangladesh is highly vulnerable to extreme sea levels because of high population exposure in the low-lying deltaic coast. Since the area lies in the monsoon region, abundant precipitation and the resultant increase in river discharge have raised a flood risk for the coastal area. Although the effects of atmospheric forces have been investigated intensively, the influence of precipitation on extreme sea levels in this area remains unknown. In this study, the influence of precipitation on extreme sea levels for three different stations were investigated by multivariate regression using the meteorological drivers of precipitation, sea level pressure, and wind. The prediction of sea levels considering precipitation effects outperformed predictions without precipitation. The benefit of incorporating precipitation was greater at Cox’s Bazar than at Charchanga and Khepupara, reflecting the hilly landscape at Cox’s Bazar. The improved prediction skill was mainly confirmed during the monsoon season, when strong precipitation events occur. It was also revealed that the precipitation over the Bangladesh area is insensitive to the El Niño-Southern Oscillation and Indian Ocean Dipole mode. The precipitation over northern Bangladesh tended to be high in the year of a high sea surface temperature over the Bay of Bengal, which may have contributed to the variation in sea level. The findings suggest that the effect of precipitation plays an essential role in enhancing sea levels during many extreme events. Therefore, incorporating the effect of terrestrial precipitation is essential for the better prediction of extreme sea levels, which helps coastal management and reduction of hazards.

    Energies, 14, 8, 2310, 2310, MDPI AG, 20 Apr. 2021, [Peer-reviewed], [Corresponding author]
    English, Scientific journal, Wind energy development has been limited by concerns associated to the varying features in wind speed which tends to destabilize the power system. This study aims to clarify the variability of winds within a day in the Philippines, specifically the hourly changes of onshore horizontal winds at 100-m hub-heights. A whole one-year experiment using the Weather Research and Forecasting model shows that onshore wind speeds decrease during the transitional hours between land breeze and sea breeze. The decreases in wind speed are most significant over coastal regions with high sloping topography. The extreme decreases in wind speed during morning hours, due to the natural processes, are found to often occur at the same time as the extreme electricity undersupply caused by the morning increase in energy demand. This result warns that the power system stability in the Philippines may become more sensitive to the variability of wind as the share of wind energy generation increases in the future. The findings of this study can contribute to promote sustainability in the operation of existing wind-reliant power systems and planning of future wind energy developments.

    Scientific journal, Abstract

    This study investigated future changes in monthly extreme precipitation in Japan during summer (June–August). The uncertainties in estimating extreme monthly precipitation were analyzed using large-ensemble regional climate simulations for both present and 4-K warmer climates. The main diagnostics were based on the 100-yr return values of monthly total precipitation PT100 estimated from a best-fit probability distribution. Under the warmer climate, PT100 was projected to increase in approximately 87%, 88%, and 78% of the total number of stations for June, July, and August, respectively, suggesting that once-per-century monthly precipitation will increase as temperature increases over a wide area of Japan, although large regional variations will exist. The western part of Kyushu and the Hokkaido region showed significant and moderately robust increases in PT100 throughout the summer months. In contrast, a considerable and robust increase was projected only in June in the Nansei Islands. The percentage change in PT100 was small in western and eastern Japan, and thus the sign of the change was uncertain. Further analysis indicated that uncertainty in internal variability is more important than uncertainty in the SST scenario for future projections of monthly precipitation extremes.

  • The Distribution of Cool Spots as Microrefugia in a Mountainous Area.

    PloS one, 10, 8, e0135732, 2015, [Peer-reviewed], [International Magazine]
    English, It has recently been proposed that microrefugia played an important role in species survival during past climate change events. However, the current distributions of microrefugia remain largely unknown. Wind-hole sites are areas affected by preferential flows of cool air generated in interstitial spaces created by rock fragments or colluvia. Alpine plant species occurring in lowland wind-hole sites isolated from alpine zones may be relicts of the last glacial period. Hokkaido, northern Japan, is known to contain many wind-hole sites in which alpine plant species can occur. Here we surveyed 55 wind-hole sites in the Kitami region, eastern Hokkaido, and observed two alpine plant species (lingonberry, Vaccinium vitis-idaea, and Labrador tea, Rhododendron groenlandicum ssp. diversipilosum var. diversipilosum) in 14 wind-hole sites. Statistical modeling showed that wind-hole sites are likely to occur in areas with high maximum slope angles and volcanic rock cover, and concave surfaces. Our predictions of wind-hole site distributions suggest that such topographic conditions are common in our study area, and that many undiscovered wind-hole sites exist. Ignoring microhabitats may greatly underestimate species distributions in topographically complex regions, and dispersed cool spots may also function as stepping stones and temporal habitats for cold-adapted species. Because these localized unique habitats usually occur in economically unproductive sites, identifying and protecting potential microrefugia (cool spots) would be a robust and cost-effective mitigation of climate change impacts.

    Hydro. Res. Lett, 8, 4, 108, 113, THE JAPAN SOCIETY OF HYDROLOGY AND WATER RESOURCES, 2014, [Peer-reviewed]
    English, This paper introduces a method named "hybrid-downscaling" to estimate the future extreme hourly precipitation intensity based on observational evidence of the 99th percentile precipitation intensity against air temperature in Sapporo and Tokyo, Japan. The future projected air temperature under the Special Report on Emissions Scenarios (SRES) A1B was used after dynamical downscaling using 3 different regional atmospheric models (RAMs) with lateral boundary conditions from 3 different general circulation models (GCMs). We analyzed the 99th percentile of hourly precipitation intensity against daily mean air temperature in Sapporo and Tokyo. The 99th percentile precipitation intensity tended to have an approximate equation in which the rate of increment was similar to the Clausius-Clapeyron rate of change in the saturated water vapor. This study also showed that the precipitable water vapor and the convective instability followed the Clausius-Clapeyron-like rate of change during the hours with the 99th percentile precipitation intensity.

  • Characteristics of Cloud Streets in the Pacific Ocean along Japan Islands under the Winter Monsoon Condition
    Kawase Hiroaki, Sato Tomonori, Kimura Fujio
    GEOPHYSICAL RESEARCH LETTERS, 32, 3, 147, 159, The Association of Japanese Geographers, 2005, [Peer-reviewed]
    Japanese, Scientific journal, Cloud streets are often observed when a cold air mass advects over a warm sea around the Japanese Islands during the winter monsoon. Thick cloud streets often appear over the southern ocean off the Japanese Islands. Visible images obtained by geostationary meteorological satellite (GMS) were analyzed to investigate the characteristics of these cloud streets during winter (January, February, December) from 1997 to 2001. The dependence of each cloud street upon the ambient wind speed and direction were investigated using reanalysis data at the level of 850hPa.
    The appearance frequency of the cloud streets differs greatly. The cloud streets in the Bungo Channel, in the lee of the east Shikoku Mountains and in the lee of the Kii Mountains are the most frequently observed. However, their frequency does not appear to depend simply on the shape of windward topography.
    The frequency of cloud streets depends not only on the ambient wind direction but also on the ambient wind speed. Some cloud streets are generated more frequently under stronger ambient wind, while others are generated less frequently. For example, cloud streets are generated more frequently over the ocean east of Kyushu and over the south of Shikoku when the ambient wind is stronger. On the other hand, cloud streets appearing in the lee of the Kii Mountains and on the Kii Channel are observed less frequently when the ambient wind is stronger.
    The position of the starting points of some cloud streets tends to shift depending on the ambient wind velocity. For example, the starting point of the cloud streets appearing in the lee of the eastern Shikoku Mountains shifts northeastward when the ambient wind velocity becomes greater.

    日本近海の水温変化傾向に関する知見をさらに進化させるため,高分解能海洋再解析データを活用して1993年以降の海洋熱波のデータセットを作成した。このデータセットの解析を行った結果,海洋熱波が2015年以降急増していること,さらに水温上昇は海面付近に限定されるものではなく,その鉛直方向の広がりは海面下数百メールにも及ぶことが明らかとなった。また,日本近海の長期的な温暖化傾向が,平成29年7月九州北部豪雨に対してどのような影響を与えていたのかを数値実験によって評価した。その結果,熱帯でみられるような気温上昇に伴う水蒸気量の増加よりも,むしろ中緯度海洋からの加湿によって生じた不安定化に伴う対流システムの上昇流強化を通じて降水量に影響を与えることがわかった。
    日本近海の水温の長期変化が極端気象にもたらす影響に関する知見を一般化する目的で,アンサンブル気候予測データベース(d4PDF)を用いて,強雨をもたらす総観場毎に強雨頻度と海面水温との関係を調べた。その結果,上空寒気や強い水蒸気移流を伴う総観場において,近海の海面水温が高いほど強雨の頻度が増加することが分かった。この他,日本周辺海域に特有な黒潮大蛇行に着目し,それに伴う海面水温が豪雨などに及ぼす影響について調べた。
    日本海の暖候期の降水粒子の特性に関する観測では,雨粒の大きさと数密度の特徴に着目した解析を新規に行い、暖候期に冷たい雨と暖かい雨と呼ばれる異なる降水過程が起きていることを示唆する観測事実を捉えることができた。A02-3班が中心に実施した日本海寒帯気団収束帯(JPCZ)の船舶観測の地上支援を実施するとともに,領域モデルによる再現実験も行うことで班間連携をさらに強化した。豪雪事例として,令和2年度の記録的豪雪に加え,2018年1月に新潟市で発生した大雪に対する海面水温の影響を調べる研究も進めた。

    インドネシアの熱帯泥炭林の炭素収支と蒸発散量の変動を解析し,火災の影響が撹乱履歴や気象条件によって異なることを明らかにするとともに,蒸発散量を蒸発と蒸散に分離することに成功した。また,泥炭の嫌気条件下での培養実験により,酸性から中性へと土壌を中和することでメタンの生成量がオーダーレベルで増加した。さらに,熱帯泥炭の放射性炭素(14C)同位体比を分析するための前処理法として,溶液試料から溶存有機炭素を固体試料として回収することに成功した。オイルパームのからのイソプレン放出能を簡易に評価するため簡易測定法を開発し,測定に最適なインキュベーション時間や温度,光照射時間等を明らかにした。
    ボルネオ島南部の熱帯泥炭林の実測データを用いて改良を行った陸域生態系モデルを,ボルネオ島西部の熱帯泥炭林のデータを用いて検証を行った結果,観測とモデル出力値には剥離があり,特に呼吸量の推定に問題があることが判明した。また,2000~2019年の衛星画像(MODIS)を収集し,各年の土地被覆図を作成した。森林のバイオマス分布を把握するため,衛星ライダーGEDIの地上部バイオマス・プロダクトを収集した。さらに,泥炭湿地林をオイルパーム農園に転換したエリアで合成開口レーダPALSAR-2(Lバンド)とSentinel-1(Cバンド)の時系列干渉SAR解析を実施し,地盤沈降量分布の時間変化を把握した。
    前年度に実施した領域気候モデル実験の空間解像度を9 kmから3 kmへと向上させた。これにより土地利用変化に対する地域気候応答の評価における不確実性の主要因の一つである積雲対流スキームを用いることなく,対流活動を再現できた。実験結果をもとに水循環に対する熱帯雨林の寄与を評価したところ,熱帯雨林は蒸発散を増加させることに加えて風の変化を通じて水蒸気フラックスの収束を強めることが分かった。

    4つの班が連携し、目的達成に向けた活動を開始した。陸域観測班は、東シベリア・カラマツ林用の海外寒冷地向けフラックス観測システムの国内試験を行った。新型コロナウイルスの蔓延により観測システムの輸送は実現していないものの、既存のシステムを活用して現地観測データを取得中である。また、過去約20年間に取得されたフラックス観測データ、衛星観測データ、モデル出力結果を収集してデータセットを構築した。東シベリアのカラマツ林観測サイトにおける正規化植生指数(NDVI)の長期変化傾向と生育期における気温と降水量の長期変化傾向との関わりを調べた結果、スパスカヤパッド(Spasskaya Pad)では生育期のNDVIが有意な増加傾向を示さず気温や降水量との相関が見いだせなかった一方、エルゲイ(Elgeeii)では生育期のNDVIが増加傾向を示し、気温と降水量の増加傾向と一致した。したがって、温暖化は北方林の生育にプラスに寄与するのみならず、降水量増加によってダメージを与えうることが示唆された。陸域モデル班は、融雪水・暖候期降水・地下氷融解水を成分分離し、北ユーラシアの河川流域におけるそれらの寄与率を定量評価可能なトレーサーモデルを開発した。東シベリアのスパスカヤパッド観測サイトにモデルを適用し、従来の観測データと比較・検証した結果、蒸発散量に対する暖候期降水の寄与が著しく大きいことを見出した。大気班は水蒸気トレーサーモデルの開発・改良に着手した。バレンツ海とカラ海における11月の海氷面積が小さいほど北極海起源の水蒸気の割合が増加し、シベリアで降水量が増加することを確認した。統括班は米国地球物理学連合(AGU)等の国際会議や国内学会での成果公表を開始した。東シベリアやモンゴルの共同研究者と協働し、2020年3月開催予定で国際シンポジウムを企画したが、新型コロナウイルスの蔓延により中止となった。

    In this study, we had aerosol and snow precipitation sampling at same time in Tomamu basin, and then measured chemical compositions of solid particles both of insoluble and soluble materials. This study produce a first approach that direct comparison of chemical components between dry and wet depositions at same time in same place. We will discuss the difference of chemical components between dry and wet depositions.
    As a result, the chemical components between inclusions in snow and aerosols are diffrent. Especially, inclusions in snow have many NaCl not but aerosols have less NaCl particles. Also, inclusions in diamond dust have less NaCl. These diffrences are probably due to the diffrence of origins of inclusion.
