湖南省云特征参数与降水相关性研究 The Cloud Characteristics Parameters and the Precipitation Correlation Studies of Hunan Province

综合利用FY2C卫星反演云参数和探空云分析方法，针对近几年湖南地区云的综合观测资料，统计分析不同云结构特征参数与降水的关系，进而探讨不同降水云系的云参数与雨强的对应关系，主要包括卫星反演云参数的频数分布特征及其与降水的关系、分析云厚度频数分布特征及其同降水的关系、云光学厚度与降水的相关性；对流云的云参数和降水的相关性分析，目的是为认识云降水发展演变规律，识别人工增雨播云条件和效果提供技术支撑。 Using the observation cloud data in the recent years of Hunan province, center of China, com-bination of inversion FY2C satellite cloud parameters and sounding cloud analysis, the rela-tionship between the different cloud structure and precipitation characteristic parameters is analyzed. Furthermore, the relationship between different precipitation cloud system’s cloud parameters and the intensity of the rain was studied, which includes: frequency distribution characteristics of satellite cloud parameters inversion and its relationship with precipitation, the thickness of the cloud frequency distribution characteristics and its relationship with pre-cipitation, the cloud optical thickness and the correlation of rainfall and correlation analysis of cloud parameters of convective clouds and precipitation. The research purposes in the grasp of the principle of the origination, development and oblivion of cloud precipitation, which is benefit for the estimate of the artificial precipitation cloud seeding condition.
