| 摘 要： | 应用GMS TBB资料对2001年亚洲夏季风活动作了诊断分析，得到中南半岛和我国南海共经历了3次季风爆发过程，且强度都强于历史同期水平；揭示了印度—孟加拉湾、中南半岛以及我国南海3个季风区季风爆发与间歇的特征。分析了季风对华南及长江中下游地区三次（6月上旬至中旬初、6月下旬至7月上旬、8月末）暴雨过程的影响，指出季风爆发及其与北方南下冷空气的结合，是造成东南部地区出现大范围长时间强降水的必要条件，从而为该地区强降水过程预报提供某些重要线索。

| Abstract: | The diagnoses and analyses of Asia summer monsoon in 2001 are made by means o f Black-Body Temperature (T BB) from Japanese GMS. It is concluded that th ere are three summer monsoon onsets over the Indochina Peninsula and the South China Se a, and the intensities are stronger than those in the same period of history. Th e results reveal the characteristics of monsoon onsets and lulls in the three mo nsoon regions (India-Bengal Bay, Indochina Peninsula, and South China Sea). Ana l ysis is also made on the influence of monsoon on the three heavy rains (from the beginning of June to the middle June, the end of June to the beginning of July, and the end of August respectively) in the South China and the middle and lower reaches of the Changjiang River. The result shows: it is the essential conditio n of large-area and long-time heavy rainfall over the Southeast China that the m onsoon onsets combine with the cool air from the North. Accordingly some importa nt clues are provided to make forecast of heavy rainfall in the region. |
