摘　　要：综合了１９７６—１９７９年及１９８９—１９９０年两次污染气象观测所得出的北京东部地区的地面风、低空风切变、逆温层等状况，并提出了当地面风为偏东风时，易形成近地逆温过程，加重对市区的污染。tilizing the observed data of air pollution in the two periods (1976-1979 and 19891990), the surface wind, low-level wind shear and temperature inversion in the eastern part of Beijing is studied. It suggests that when surface wind is easterly wind,it is easy to form surface inversion,which makes the urban pollution become more serious.
