【摘要】 用中央气象局以及有关省(区)出版的1951—70年的228个站的旬降水量资料和1960—69年的高空风资料,分析了我国主要相对多雨带的季节变化,发现在105°E以东的我国东部地区和青藏高原地区相对多雨带具有完全不同的特征。相对多雨带与低层流场辐合线有很好的对应关系。南亚高压和西太平洋副高对相对多雨带的演变有重要的影响。更多还原

【Abstract】 Using the deca-day rainfall data of 228 Stations in 1951-70 and upper wind data in 1960-69 published by Central Meteorological Bureau and some relevant provinces, we analysed the seasonal variation of the main rain-belts and found many features for the rain-belts located in the eastern China to the east of 105°E and the Qinghai-Tibetan Plateau. The eastern rain-belts are closely related with low level flow convergence line. The South Asia high and the Western Pacific subtropical high have significant influence on the development of the rain-belts.更多还原
