摘要
我国西部 (85°10 5°E)冬季“扰动源涡”的位置对夏季东部雨带的配置具有支配作用。当西部“源涡”位于 35°N以北时 ,东部雨带多出现在黄河流域及其以北 (Ⅰ类雨型 ) ;源涡位于 32°35°N之间时 ,夏季雨带多出现在淮河流域 (Ⅱ类雨型 ) ;当源涡位于 32°N以南时 ,雨带多出现在长江流域或江南 (Ⅲ类雨型 )。
In summer, the distribution of rain belt over East was controlled by the last winter position of Disturb source vortex over West China, during 85°E to 105°E latitude. The vortex is to the north of 35°N longitude, the belt is occurred in Yellow River reaches and to the north (first rainfall pattern-Ⅰ) in summer; between 32°N and 35°N longitude, the belt is appeared in Huaihe River basin (second pattern-Ⅱ); and the vortex is down to the south of 35°N, the belt is in Yangtze River basin and/or Jiangnan area ( third pattern-Ⅲ ). In the hotspot region over south east of Tibet, the stronger geothermal pulse in winter has more important influence for climate disaster in next summer over Yangtze River, Huaihe River reaches and Sichuan, Guizhou area of China.
