英文摘要: This project focuses on the significant problems in weather modification research. Based on the analyses of cloud water path data and the other datasets and combined with data analysis and numerical simulation methods, studies are performed on the climatic features and mechanism of cloud water variation. Using ISCCP and MODIS cloud water path data, climatic features and mechanism of cloud water path are investigated. Using GPCP precipitation dataset, cloud water cycle index data are calculated and the long-term features are analyzed. Combined with satellite and aircraft cloud water observations and ERA-40 reanalysis dataset, the dependence of cloud water on temperature is studied. The precipitation enhancement potential regions are identified according to climatic perspective and cloud water conversion features of typical cloud system are simulated. This project can provide scientific envidence and reference to long-term weather modification and cloud water resource exploitation and results of this project have a good practical utility in cloud water resource exploitation.
