【摘要】Based on regional meteorological observatory data in Panjin area during 2007-2011,the interannual,monthly,intensity,spatial and temporal distribution variation characteristics of short-time strong rainfall in Panjin area were analyzed. The results showed that frequency of short-time strong rainfall in Panjin City was high,mainly occurred from May to September,the maximum frequency occurred in July,followed by August,the least was in October.The short-time strong rainfall in Panjin area generally conformed to the regulation of the stronger precipitation intensity corresponding the smaller frequency,but frequency of 40~50 mm/h precipitation appeared slightly higher than that of 30~40 mm/h precipitation. In Panjin area,the spatial distributed unevenly,less frequency appeared in the central and southern area,while more frequency appeared in northwest and southeast.%利用盘锦地区2007℃2011年区域气象观测站资料,分析了盘锦短时强降水的年际、月际以及强度、空间分布变化特征。结果表明：盘锦市短时强降水发生频率较高,集中发生在5℃9月,7月发生频次最多,其次为8月,最少的是10月；盘锦市短时强降水一般符合降水强度越强出现频次越小的规律,但40~50 mm/h降水出现的频次略高于30~40 mm/h降水等级出现的频次；盘锦短时强降水频次空间分布
