| 摘 要： | 用正压原始方程模式，对热带气旋穿越副热带高压的异常路径进行了数值试验，揭示出热带气旋自身特征及其与副高中心的经向距离、副高的位置和强度变化是直接影响热带气旋移动路径的敏感因子。也反映出热带气旋与其邻近的天气尺度的副热带高压以及β效应三者之间非线性相互作用的复杂机制。

| Abstract: | It is pointed out in the paper that the geographical distribution of source/sink for water vapor can be correctly reflected only by seasonal mean water moisture flux divergence summed up vertically.Results show that the west Pacific(120-133°E) and the Bay of Bengal are the sources of water vapor in Asian monsoon area in August,in which,the five strongest ones are located in east of Philippines,Sulu sea,Huang Hai Sea,Andaman Sea and Brahmaputra Valley.The South China Sea is a sink,not a source of water moisture.The rainfall in North China is mainly under the influence of two Monsoon systems in Asia and the water source in Huang-Hai Sea and Brahmaputra Valley. |
