影响黑龙江的两次致灾台风暴雨对比分析

Comparative analysis of two disastrous typhoon rainstorms affecting Heilongjiang Province

应用常规资料、非常规资料,对2019年第13号台风“玲玲”和2012年第15号台风“布拉万”影响黑龙江省的暴雨特征进行对比分析。结果表明:“玲玲”和“布拉万”这两个台风在西太平洋经过升级后均进入东海,并与东南岸保持一定距离,不受陆地摩擦作用影响,同时开始受副高西部引导气流影响,一路向北,都以乎近直线的路径,径直向北移动。从位置与强度对比来看,“玲玲”较“布拉万”强度更大,降水更强,风力更大;下垫面条件的改变,对台风“玲玲”的强度变化和风速有一定影响。

Based on conventional data and unconventional data,the rainstorm characteristics of No.13 typhoon“Lingling”in 2019 and No.15 typhoon“bulawan”in 2012 in Heilongjiang Province are compared and analyzed.The results show that the two typhoons,Lingling and bulawan,entered the East China Sea after upgrading in the Western Pacific,It keeps a certain distance from the southeast coast,and is not affected by land friction.At the same time,it begins to be affected by the airflow guided by the west of the subtropical high,all the way to the north,moving straight to the north in a nearly straight path.From the comparison of location and intensity,"Lingling"is stronger than“Bulawan”,with stronger precipitation and greater wind;Changes in the underlying surface conditions have a certain impact on the intensity changes and wind speed of Typhoon Lingling.
