スコープ和文水蒸気は放射冷却と凝結による潜熱放出により対流圏の大気大循環を駆動するが、その流れの中には等方的な乱流、層積雲や積乱雲、スコールラインや熱帯低気圧、さらにはマッデン・ジュリアン振動のような大規模現象まで、複雑で豊かな階層構造が形成されている。水蒸気は大きな空間スケールで長い時間をかけて蓄積され、流れに乗って輸送されるが、その凝結は短時間に小さい空間スケールで起こる。また、水蒸気や雲は地球の放射収支にも影響を与えるため、長期の気候変化を調節しているかもしれない。本セッションでは、水蒸気と組織化した雲群の相互作用を記述する湿潤大気科学の確立を将来目標に据え、理論・観測・モデルを問わず幅広い時空間スケールを対象とした研究を募集する。海大陸研究強化年(YMC)の現地観測や放射対流平衡実験のモデル間比較(RCEMIP)などの最新の知見を共有し、研究者間のコミュニケーションを円滑にすることで、長年の困難に対する突破口を開きたい。
英文Water vapor plays a significant role in regulating the global atmospheric circulation, especially in the troposphere. The overturning circulation is directly driven by the longwave radiative cooling of water vapor and the latent heating/cooling through microphysical processes to balance it. This global circulation is composed of diverse atmospheric phenomena with various spatial and temporal scales. Developments of some significant turbulent motions such as 3D isotropic turbulence in clouds, stratocumulus and cumulus convection, squall lines and tropical cyclones, and the Madden-Julian oscillation, are essentially associated with moisture anomaly in each scale. Moisture is accumulated relatively slowly in larger horizontal scales, but is consumed relatively quickly in smaller ones. This significant scale gaps between the accumulation and consumption may be one of the causes of the long-lasting difficulty in developing the theory of the moist atmosphere. The aim of this session is to share the recent researches about the relationships between moisture and organized cloud systems in wider spatial and temporal scales to enhance collaborations between modeling, observational, and theoretical approaches in tackling this challenging task. Research results relating to the Years of the Maritime Continent (YMC) and Radiative-Convective Equilibrium Model Intercomparison Project (RCEMPI) are welcome.
