9613979 Arakawa This award provides continued support for a research project devoted to the improving the representation of the physical processes relating to humidity and cloud fields in numerical models of the global atmosphere. In large part, the new research represents a continuation of activities and involves a broad range of topics. Among them are the development of a global version of a hybrid vertical coordinate model which will be used to simulate frontal clouds ; assessing the impact of including ice phase processes in a cloud updraft/downdraft model; improvement, based on cloud ensemble model results , of the cumulus parameterization; a statistical analysis of observations with a view to cumulus parameterizability; formulation of the decaying process for ice clouds; improving the formulation of the planetary boundary layer moisture budget; and the development of the parameterization of orographic gravity waves. Dr. Arakawa is acknowledged to be one of the great leaders in the field of numerical modeling of the atmosphere and continues to be quite productive. This project is supported jointly by the NSF through this award and NASA through a separate award. ***

9613979荒川奖继续支持一个研究项目，该项目致力于改善全球大气数值模式中与湿度和云场有关的物理过程的表现。在很大程度上，这项新的研究代表着活动的继续，并涉及广泛的主题。其中包括：开发将用于模拟锋面云的混合垂直坐标模式的全球版本；评估在云上升气流/下降气流模式中纳入冰相过程的影响；根据云系模型结果改进积云参数化；为了积云的可参数化性而对观测进行统计分析；冰云衰减过程的公式；改进行星边界层水分收支的公式；以及地形重力波的参数化的发展。荒川博士被公认为是大气数值模拟领域的伟大领导者之一，并将继续卓有成效。该项目由美国国家科学基金会通过该奖项和美国国家航空航天局通过一个单独奖项共同支持。***
