| 摘 要： | 使用１９５１～１９８９年浙江省６８个气象测站资料，统计分析了该省大暴雨的时空特征。梅讯期（５月～７月中旬）大暴雨集中在６月中下旬，主要出现在浙西和浙西南地区；台汛期（７月下旬～１０月）集中在７月底８月初和９月前半月，多发生在浙东南沿海地区，在不同季节的环流背景下，产生大暴雨的天气系统迥然不同，梅汛期主要是西风带偏西气而和副热带高压后部的西南气流形成的梅雨锋及与它产生作用的高原槽、西风槽、西南涡、切变线等天气系统．台汛期主要是东风带控制下的台风、台风倒槽、东风波等天气系统。最后指出，大暴雨产生与区域地形存在着密切关系。

| Abstract: | Data in period from 1951 to 1989 at 68 meteorological stations in Zhejiang Province have to the investigation in order to obtain temporal and spatial climatic features,The results are the following :(1)dur-ing the Mei-Yu Season(from May to mid July ),the major regions for large heavy rainfall are in the westernand southwestern parts of the province,whereas turn to southeast coastal region during the typhoon season(late July to October );(2)The occurrence of large heavy rainfall has some specific time periods,it concen-trates in mid to late June during the Mei-Yu Season,end July to early August and the first half of Septemberduring the typhoon season. The weather systems producing large heavy rainfall are different with seasons andthe rainfall is influenced by the topography significantly. |
