积云对流组织化现象已为大量观测事实所证实，而目前数值模式中通用的积云参数化方案缺乏描述有组织积云对流过程的机制，对东亚有组织对流降水模拟预测能力有限。本项目针对东亚有组织对流降水典型个例，诊断分析东亚有组织对流降水的环境条件及对流组织化特征，寻找到指示对流组织化特征的动力因子，作为参数化方案的动力控制，发展和构造适合于东亚有组织对流的积云参数化方案。本项目研究将加深积云对流引发多尺度系统相互作用的理解，揭示积云对流对大中尺度环境反馈物理机制，发展后的方案将植入WRF中尺度模式，提高东亚有组织对流降水过程的模拟及预测能力。

The phenomenon of organized cumulus convection has been confirmed by amount of observations, but the current cumulus parameterization schemes of current numerical models have not descriptive mechanism of cumulus organized convection, thus the prediction and simulation about the organized convective precipitation need to be improved. In this project, the typical organized convection precipitation will be simulated and diagnosed, and the environmental conditions and convective features of organized convection will be analyzed. In attention, dynamical factor as the dynamical control of parameterization scheme will be diagnosed, which can be used to indicate the organized convection. The cumulus parameterization scheme will be developed, which is suitable for the simulation of the organized convective precipitation in East Asia. This research will deepen understanding of the interactions of multi-scale systems and reveal the feedback mechanisms between cumulus convection and large scale environment. The developed scheme will be used in WRF model so as to improve the prediction and simulation about the organized convective precipitation in East Asia.
