Numerical Modeling of the Global Atmosphere

该奖项为一个研究项目提供了持续的支持，该项目致力于改善全球大气数值模型中与湿度和云场有关的物理过程的表现。在很大程度上，新的研究代表了活动的延续，涉及广泛的主题。其中包括开发全球版本的混合垂直坐标模式，用于模拟锋面云；评估在云上升/下降气流模式中纳入冰相过程的影响；基于云系综模式结果的积云参数化改进从积云参数化的角度对观测数据进行统计分析冰云衰变过程的公式；改进了行星边界层水分收支公式；地形重力波参数化研究进展。Arakawa博士被公认为大气数值模拟领域的伟大领导者之一，并继续取得相当大的成果。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单独的奖项共同支持。＊＊＊

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. ***
