摘要
用40多年资料对浙江暴雨、大暴雨的时空分布进行气候分析,并对梅汛期间产生的历次暴雨前12～24h的天气形势进行分析归类.得出:浙江暴雨、大暴雨的气候概况,产生梅汛期暴雨的主要天气形势有:移动低槽型、冷锋切变型、低涡暖锋切变型、北槽南涡型四大类天气形势.再通过历史暴雨个例的相似检索,可以找出目前天气形势与历史上相似的暴雨个例,并可以按相似个例作出暴雨的诊断预报.
It was by using 40-year heavy rainfall synoptic data that Zhejiang's hard rain and heavy rainfall climate characters were studied and that synoptic situation which was 12-24 hours before every storm rainfall in plum rains season was analyzed and classified. According to Zhejiang's heavy rainfall climate characters, the main synoptic situation of storm rainfalls in plum rains season was partitioned into four classes. They are migrating through of low pressure type , cold front with shearing deformation type , warm front with vortex and shearing deformation type , and a through in north and a vortex in south type. It may make heavy rainfall forecast by using present meteorological data compared with historic heavy rainfall examples.
