中文摘要: 研究了黑龙江省7、8月雨涝发生时500hPa环流盛行定常行星波列,以及它们前期4～6月环流演变情况。并研究了雨涝发生时全国多为A型雨型即北多南少;6月盛行B型雨型即黄河和华南多雨,又可分为一个副型为B1雨型即两江多雨型,长江、松花江流域多雨,其它少雨;5月和4月分别盛行C和D雨型,即黄河流域多南北少和长江以北多以南少。并指出河套与山西、河北北部多雨是造成黑龙江省雨涝的关键区。

Abstract:During flood happened in Heilongjiang Province , at 500hPa geopotential height circulation anormaly field prevail series ″+-+-″ quasi-stationary planetary wave and the circulation evolution tendency the fore of April-June . When flood happened , it prevail ″A″ rainfall type , or above normal in northern of China and below normal in south China . In June Prevail ″B″ rainfall type , or Huanghe River and the south of China above normal the other below normal,it is also divided by ″B1″ deputy type, or Changjiang River and Songhuajiang River above normal , the other below normal . In May and April prevail ″C″ and ″D″ rainfall type , or Huanghe River above normal and in the south and in the northern region below normal and the northern of Changjiang above normal and the south of Changjiang below normal . And indicate solicitation flood key area that is Huanghe River middle region and northern of Shanxi and Hebei Province above normal .
