摘　　要：利用浙江69个常规气象观测站近17年春季逐日降水和日照数据,分析了浙江省春季连阴雨的时空分布和强度变化特征。结果表明:春季连阴雨呈南多北少的特征,北部平原地区连阴雨次数接近南部山区的50%;春季连阴雨与地形因素密切相关,南部山区连阴雨次数较多且持续时间较长;南部山谷地区春季连阴雨具有频率高、持续日数相对周边地区较短、降水量大等特征。同时,探讨连阴雨天气对农业生产的影响及防范措施,以便进一步提高气象为农服务水平。Based on the daily precipitation and sunshine data of 69 conventional meteorological stations in Zhejiang Province in the past 17 years,the spatialtemporal distribution and intensity change characteristics of continuous rain in spring in Zhejiang Province are analyzed.The results show that the continuous rain in spring is more in the South and less in the north,and the number of continuous rain in the northern plain is nearly half of that in the southern mountainous area;The continuous rain in spring is closely related to the topographic factors.The continuous rain in the southern mountainous area is frequent and lasts for a long time;The continuous rain in spring in the southern Valley has the characteristics of high frequency,short duration days and large precipitation compared with the surrounding areas.At the same time,the influence of continuous rainy weather on agricultural production and preventive measures were discussed in order to further improve the level of meteorological service for agriculture.
