Analysis of Weather Element Charcterisies and Air Pollution Status during Continuous Fog Days in Liaoning
摘要
Abstract
[Objective］The aim was to diacuss the formation ,duration and disappearance of log.[Metthod ]Based on the weather data and physics of liaoning Province, and considering the continous 4 days foggy in 11 places Liaoning from November 29,2009 to December2,2009 ,detailed analysis of this consecutive foggy days was given proceeding from the weather situation ,element charateriscs. especially the occurrence,duration and disappearance of dense fog.[Result] This dense fog was because that Liaoning was in the saddle pressure field.The wesk cold air divergence set the ground in many wesk mild scale convergence areas. The high temperature inthe early time resulted in melting snow and long duration of dence fog days ,along with radiation low temperature and suthwest convergence transmis sin.In the meantime ,because of the existence of small wind speed and existence of upper inversion temperatre layer,it was inconvenent for the divergenceof wet air;in addition ,there was dense fog north China.The upper southwest southwest airstream tranmitted wet air in the north China to the air ofLiaoning,increasing the intensity of dense fog in Liaoning.[Conclusion] The study offered reference for the further forecast of aif pollution.关键词
