【摘要】 本文选自上海市1984年11月27日至12月5日的一次典型大气污染过程,分析同期气象要素和天气图形势,初步结果表明:上海市区1公里以下低空风速微弱、地面静风,强而厚的贴地逆温层等,同高浓度大气污染关系密切.500hpa 西太平洋副高短时期北上,地面上苏北小冷高压变性东移时.福建小高压影响上海,是形成贴地层逆温和1公里以下低层弱风场的重要环流形势.更多还原

【Abstract】 Selecting a typical air pollution process in shanghai from later Nov.to early Dec.1984,the relationship between pollution process and localmeteorological conditions were analysed,preliminary result showed thatthe formation of thick and strong inversion of the lowest layer and calmor smaller wind speed below 1000 meters above the ground were importantmeteorological factors to form higher air pollution.Fujian anticycloneinfluences shanghai when north Jiangsu small cold high moves to east onthe ground.This is the important circulation situation to form the lowestinversion layer and faint wind field below lkm above the ground.更多还原
