【摘要】 利用1960～2003年间登陆影响我国的热带气旋及其造成的降水资料,对44年间登陆我国热带气旋降水时空变化特征进行统计分析,结果表明:热带气旋降水与热带气旋登陆活动相一致,主要发生在5～11月,其中7～9月为盛期;热带气旋降水量以及热带气旋暴雨日数的分布是自南向北、从沿海到内陆迅速减小,最大出现在海南和华南、东南沿海地区;热带气旋强度越强其最大过程降水一般也就越大,但是二者并非严格的线性关系;1960年以来,我国受台风影响的绝大部分地区台风降水呈波动下降的趋势。更多还原

【Abstract】 Based on the data of the tropical cyclones(TCs) landing on China and the relevant induced rainfall from 1960-2003, study is carried out of the climate characteristics of the TC-induced rainfall. Results show that, TC rainfall occurs from May to November, with the most active period from July to September, associated with the TC landfall activities. Spatial distribution of the TC rainfall and the frequency of TC rainstorms illustrates that they decrease dramatically northwards and inlandwards with the maximum in Hainan Province and the coastal area of South China and Southeast China. The maximum rainfall for the whole process of TC landfall has an approximately linear relationship with TC intensity. TC rainfall in most TC-affected areas in China decreases wavily since 1960.更多还原
