摘要
对2005年2月16～18日南疆西部暴雪天气分析表明,暴雪是塔什干低涡与地面倒流冷空气共同作用的结果。物理量诊断分析表明暴雪出现在低层辐合上升强、高层辐散下沉弱的区域,这种高低空配置加剧了大气垂直上升运动及对流发展,使大量不稳定能量得以释放。
The analysis of the snowstorm on 16～18 February 2005 in west of South-Xinjiang showed that the snowstorm was resulted from both the eddy in Tashkent and the surface eastly wind.Diagnostic analysis of physical quantity showed that snowstorm occurred in the area of the low-level airconvergence and upper level air divergence,which caused vertical ascending air and convection process and brought the release of unstable energy.
