河北中南部连续12 d重霾污染天气过程特征及影响因素分析
Analysis on the Characters and Influencing Factors of a 12 d Heavy Haze Pollution Weather Process
摘要
Abstract
From 14 to 25 December 2013,a heavy haze pollution process occurred in the central and south-ern part of Hebei.By analyzing the meteorological conditions,flow field and characteristics of pollutants, the causes of this process are discussed.This pollution process which was closely related to haze presented such features as long duration,wide range and great intensity.With large-scale stagnant meteorological condition and near-surface atmospheric stratification,pollutants accumulated rapidly in the convergence zone of surface wind,leading to the formation of this heavy pollution process.There were two weak cold air activities during this period,but they were too weak to change the stagnant atmospheric stratification. Thus,the heavy pollution process,this time lasted a long time.关键词
