摘　　要：2012年8月底和2019年9月初分别受台风“布拉万”和“玲玲”影响,辽宁地区出现两次强度不同的暴雨天气。本文利用中国台风网下发的台风路径资料,ECMWF再分析资料和辽宁地区观测站资料等对辽宁地区两次暴雨过程进行天气学诊断对比分析。结果表明:“布拉万”导致辽宁中部地区产生暴雨天气,“玲玲”导致辽宁东部产生暴雨天气,“布拉万”在辽宁产生的降水量和降水范围都更大;两次台风过程台风均沿副高外围运动,高温高湿的空气与贝加尔湖向东南输送的冷空气交汇产生降水。In late August 2012 and early September 2019, the Liaoning region was affected by Typhoon Bolaven and Typhoon Lingling respectively, experiencing two rainstorm events with different intensities. In this paper, typhoon track data issued by the China Typhoon Network, ECMWF reanalysis data, and observational station data in the Liaoning region were used to conduct a synoptic diagnostic and comparative analysis of the two rainstorm processes in the Liaoning region. The results show that Typhoon Bolaven caused rainstorms in the central part of Liaoning, while Typhoon Lingling led to rainstorms in the eastern part of Liaoning. The precipitation amount and range generated by Bolaven in Liaoning were larger. During both typhoon processes, the typhoons moved along the periphery of the subtropical high. The air with high temperature and humidity converged with the cold air transported southeastward from Lake Baikal, resulting in precipitation.
