    In order to investigate a possible variety of atmospheric states realized on a synchronously rotating aqua planet, an experiment studying the impact of planetary rotation rate is performed using an atmospheric general circulation model (GCM) with simplified hydrological and radiative processes. The entire planetary surface is covered with a swamp ocean. The value of planetary rotation rate is varied from zero to the Earth's, while other parameters such as planetary radius, mean molecular weight and total mass of atmospheric dry components, and solar constant are set to the present Earth's values. The integration results show that the atmosphere reaches statistically equilibrium states for all runs; none of the calculated cases exemplifies the runaway greenhouse state. The circulation patterns obtained are classified into four types: Type-I characterized by the dominance of a day-night thermally direct circulation, Type-II characterized by a zonal wave number one resonant Rossby wave over a meridionally broad westerly jet on the equator, Type-III characterized by a long time scale north-south asymmetric variation, and Type-IV characterized by a pair of mid-latitude westerly jets. With the increase of planetary rotation rate, the circulation evolves from Type-I to Type-II and then to Type-III gradually and smoothly, whereas the change from Type-Ill to Type-IV is abrupt and discontinuous. Over a finite range of planetary rotation rate, both Types-III and -IV emerge as statistically steady states, constituting multiple equilibria. In spite of the substantial changes in circulation, the net energy transport from the day side to the night side remains almost insensitive to planetary rotation rate, although the partition into dry static energy and latent heat energy transports changes. The reason for this notable insensitivity is that the outgoing longwave radiation over the broad area of the day side is constrained by the radiation limit of a moist atmosphere, so that the transport to the night side, which is determined as the difference between the incoming solar radiation and the radiation limit, cannot change greatly.

    We examine the results of the Aqua-Planet Experiment Project (APE), focusing mainly on the structure of equatorial precipitation in the subset of participating models for which the details of model variables are available. Despite the unified setup of the APE, the Hovmollor plots of precipitation in the models exhibit a considerable degree of diversity, presumably as a result of the diversity among the implementation of the various physical processes. Nevertheless, the wavenumber-frequency spectra of precipitation show certain similarities, and the power spectra can be divided into Kelvin, westward inertio-gravity, and "advective" components. The intensity of each of these three components varies significantly among different models. The composite spatial structures corresponding to these three components are produced by performing regression analysis with space-time filtered data. The composite horizontal structures of the Kelvin and westward inertio-gravity components are similar among the models, and resemble those expected from the corresponding equatorial shallow-water wave modes. These resemblances degrade at the altitude levels where the value of phase velocity approaches the zonal mean zonal wind speed. The horizontal structure of the advective component diverges significantly among the models. The composite vertical structures are strongly model dependent for all three components. The comparison of the vertical and horizontal structures associated with convective and stratiform heating of the composite disturbances indicates that the diversity of the vertical structures originates from differences in the implementation of the physical processes, especially the implementation of cumulus parameterization.

    In this paper, we examine the steady state responses of models participating in the Aqua-Planet Experiment Project (APE) to the zonal asymmetry of equatorial sea surface temperature (SST) anomalies (SSTAs). Experiments were performed using three different SSTA distributions, i.e., two localized SSTAs with a common shape but different intensities, and an SSTA that varied with zonal wavenumber one. The structure of the responses obtained differs significantly among the models; however, some common features are also present.The principal features of the responses to the localized SSTAs are a positive precipitation anomaly over the warm SSTA, a widespread negative precipitation anomaly along the intertropical convergence zone, a pair of Rossby wavetrains along the equatorward flanks of mid-latitude westerly jets originating from a pair of upper tropospheric anticyclones that develop to the east of the warm SSTAs, and zonally wavelike precipitation and geopotential anomalies along the baroclinic zones. The structure of the tropical responses differs considerably from the Matsuno-Gill pattern, and the magnitude of the responses is almost proportional to the intensity of the localized SSTA in each of the models.The responses to the zonal wavenumber one SSTA are dominated by zonal wavenumber one structures. Around the longitudes of the warm (cold) SSTA, tropical precipitation increases (decreases). At longitudes east of the positive precipitation anomaly, the region of nearly zero absolute vorticity near the equator in the upper troposphere expands polewards, and the midlatitude westerly jets become narrower and stronger. To the west of the positive precipitation anomaly, the upper tropospheric region of nearly zero absolute vorticity shrinks, and the mid-latitude jets become weaker but broader, so that the regions of westerly winds extends to the equator, which results in the development of a zonal mean westerly wind anomaly around the equator. The longitudinal shift of the upper tropospheric westerly zonal wind anomaly relative to the precipitation anomaly is in marked contrast to that associated with the Walker circulation and the convection center around the Maritime Continent.

    Hydrodynamic escape of hydrogen driven by solar extreme ultraviolet (EUV) radiation heating is numerically simulated by using the constrained interpolation profile scheme, a high-accuracy scheme for solving the one-dimensional advection equation. For a wide range of hydrogen number densities at the lower boundary and solar EUV fluxes, more than half of EUV heating energy is converted to mechanical energy of the escaping hydrogen. Less energy is lost by downward thermal conduction even giving low temperature for the atmospheric base. This result differs from a previous numerical simulation study that yielded much lower escape rates by employing another scheme in which relatively strong numerical diffusion is implemented. Because the solar EUV heating effectively induces hydrogen escape, the hydrogen mixing ratio was likely to have remained lower than 1 vol% in the anoxic Earth atmosphere during the Archean era.

    A long-term numerical simulation is performed to investigate idealized characteristics of the cloud layer of Jupiter's atmosphere using a two-dimensional cloud convection model that treats thermodynamics and microphysics of the three cloud components, H(2)O, NH(3), and NH(4)SH. A prominent result obtained is intermittent emergence of vigorous cumulonimbus clouds rising from the H(2)O condensation level to the tropopause. Due to the active transport associated with these clouds, the mean vertical distributions of cloud particles and condensible gases are distinctly different from the hitherto accepted three-layered structure; considerable amounts of H(2)O and NH(4)SH cloud particles exist above the NH(3) condensation level, while the mixing ratios of all condensible gases decrease with height from the H(2)O condensation level. The mean vertical profile of NH(3) vapor is consistent with the results of radio observations in that the abundance of NH(3) is subsolar below the NH(3) cloud base. Citation: Sugiyama, K., K.

    Unstable modes of a linear shear flow in shallow water on an equatorial beta-plane are obtained over a wide range of values of a non-dimensional parameter and are Interpreted in terms of resonance between neutral waves. The non-dimensional parameter in the system E 1(gH beta(2)) where y, g, H and beta are the meridional shear of basic zonal flow, gravitational constant, equivalent depth and the north-south gradient of the Coriolis parameter, respectively. The value of E is varied within the range -2.50 <= log E <= 7.50. The problem is solved numerically in a channel of width 5 gamma 3. The structures of the most unstable modes, and the combinations of resonating neutral waves that cause the instability, change according to the value of E as follows. For log E < 2.00, the most unstable modes have zonally non-symmetric structures; the most unstable modes for log E < 1.00 are caused by resonance between equatorial Kelvin modes and continuous modes, and those for 1.00 < log E < 2.00 are caused by resonance between equatorial Kelvin modes and westward mixed Rossby-gravity modes. The most unstable modes for log E >=, 2.00 have symmetric structures and are identical with inertially unstable modes. Examinations of dispersion curves suggest that non-symmetric unstable modes for 1.00 <= log E < 2.00 and inertially unstable modes for log E >= 2.00 are the same kind of instability.

    For the purpose of examining the initial development of the atmospheric response to a warm SST anomaly placed at the equator, an ensemble switch-on experiment is conducted with an aqua-planet GCM. An ensemble average of the size of 128 significantly reduces the transient noises caused by both small scale convective activity and large scale intraseasonal variability. In the first three days after the switch-on of the SST anomaly, a convection center develops above the warm SST area. As a barotropic response to the heating of convection center, a global increase of surface pressure occurs outside the low pressure region around the warm SST area. The response after the emergence of the high pressure anomaly is consistent with Gill (1980); a warm Kelvin wave-like anomaly is emitted to the east of the convection center, while a warm Rossby wave-like anomaly is emitted to the west. The Kelvin wave-like signal propagates at a speed slower than that of free Kelvin wave expected from its vertical wavelength, suggesting that the signal is a "moist" Kelvin wave. Transient decrease of precipitation occurs at the moist Kelvin wave front; a decrease of convection associated with the downward motion at the wave front is consistent with its slow propagation. After several days, precipitation recovers and is even intensified because of the surface frictional convergence associated with the Kelvin wave-like equatorial low pressure anomaly. To the west of the warm SST area, on the other hand, precipitation decreases monotonically. The continuous reduction of precipitation is caused by the equatorial surface frictional divergence associated with the relatively high pressure anomaly at the equator of the Rossby wave structure. Finally, there appears a slow zonally symmetric response within the Hadley cell characterized with surface pressure rise in the tropics and westerly wind anomaly in the troposphere. The change of eddy zonal momentum transport, together with the transport toward the lower level by the Hadley circulation and the geostrophic adjustment to the resulting low level westerly acceleration, seems to be responsible for the response.

    Linear stability of rotating thermal convection in a horizontal layer of Boussinesq fluid under the fixed heat flux boundary condition is examined by the use of a vertically truncated system up to wavenumber one. When the rotation axis is in the vertical direction, the asymptotic behavior of the critical convection for large rotation rates is almost the same as that under the fixed temperature boundary condition. However, when the rotation axis is horizontal and the lateral boundaries are inclined, the mode with zero horizontal wavenumber remains as the critical mode regardless of the rotation rate. The neutral curve has another local minimum at a nonzero horizontal wavenumber, whose asymptotic behavior coincides with the critical mode under the fixed temperature condition. The difference of the critical horizontal wavenumber between those two geometries is qualitatively understood by the difference of wave characteristics; inertial waves and Rossby waves, respectively.

    Moist convection of Jupiter's atmosphere is examined using a large-domain two-dimensional fluid dynamical model with simplified cloud microphysics of water. The result shows that the water condensation level acts as a dynamical and compositional boundary. The convection below the condensation level is characterized by a steady regular cellular structure and a homogeneous distribution of water mixing ratio. Above the condensation level, cloud elements accompanied by the upward motion develop and disappear irregularly but successively, and water mixing ratio is highly inhomogeneous. The horizontal average of mixing ratio decreases rapidly with height just above the condensation level, resulting in a distinctive stable layer at 5 bar. The stable layer prevents the air masses above and below it from mixing with each other. As a result, the upper dry air does not reach 20 bar level, where the Galileo probe observed low humidity.

    Striking 20-30-day sea surface temperature waves observed along the equatorial front in the later half of the year are generally believed to be of an oceanic origin. Here we report the detection of atmospheric waves that are unambiguously tied to these oceanic waves, using new satellite measurements of surface winds. A general circulation model simulation reveals that these atmospheric waves have a shallow vertical structure trapped in the planetary boundary layer (PBL), unlike El Nino/Southem Oscillation where changes in deep convection are the cause of anomalous winds. Vertical wave motion penetrates well above the PBL and is likely to impact the distribution and transport of climatically important gas species such as ozone and dimethyl sulfide.

    熱帯に局在する暖水域が熱帯域の大規模な降水分布に与える影響を調べるために水惑星実験を行った。用いた数値モデルは、T42L16の分解能を持つ全球プリミティブモデルであり、簡略な水過程を含む。暖水域は、東西一様南北対称なSST分布をもつ海洋の赤道上に置いた。得られた熱帯域の降水分布は、暖水域の西側での降水減少と東側の広範な領域での増加、という東西非対称性の発生に特徴付けられる。その傾向は用いた積雲のパラメタリゼーション(対流調節とKuoスキーム)によらない。西側では、中層の昇温による安定度の増加と下降流が見られ、降水の減少と整合的であった。東側では、中層の昇温はあるものの、下層での南北収束による水蒸気の増加が安定度の減少をもたらし、降水の増加と対応していた。蒸発の評価に用いられる下層風速を固定した実験を行った結果、非対称な降水分布の生成にWISHEは重要な要因とはなっていないことが示された。
