摘要
2004年12月24—30日,淄博地区出现一次持续一周的强空气污染过程。本文分析了这次过程的主要污染物浓度变化特征和造成强污染的天气形势特点以及主要的气象变量分布特征。结果表明:高空维持稳定纬向环流、逆温层结持续存在、混合层厚度增加、低空风速小,导致污染物不能及时随大气扩散,污染物浓度增大。
Sustained heavy air pollution episode occurred in Zibo during 24 -30 December, 2004. The characteristics of air pollution, the meteorological factors and the related synoptic processes were analyzed. Investigation indicates that air pollutants were greatly retained by the stable atmospheric stratification, inversion layer, decreased thickness of atmospheric mixed layer and the light low-level wind speed. It is easy to form high concentration.
