江苏连续三次区域性浓雾形成过程的机理分析
An analysis for three successive fogs formation mechanisms in Jiangsu
摘要
Abstract
Based on normal observation data,NCEP/NCAR reanalysis data,wind profiler data and automatic visibility observation data,the characteristics and occurring and developing mechanisms of three fog weather processes in early December,2013 in Jiangsu were analyzed with focus on formation of frontal fog.Results show that the three fogs was formed in favorable but different largescale circulation.The radiation fog was formed by radiation cooling at surface and upper level humid wind,maintained by middle-level inversion and ground inversion with help of boundary low-level jet.The advection fog was formed by warm wet advection flowing into Jiangsu from sea and maintained by vapor from Southeast and stable inversion.The frontal fog generated in front of the frontal zone was formed by cool advection.The sufficient vapor accumulation and flux divergence make dense fog exist.关键词
