摘　　要：对2012年11月10—11日朝阳县暴雪天气的大尺度天气系统、常规物理量、卫星雷达图进行诊断分析,得出此次暴雪天气是在有力的大尺度环流形势下发生的,低层辐合、高层辐散以及强上升运动为暴雪提供了良好的动力条件,同时能量锋区以及水汽的辐合与输送是暴雪产生的主要原因。The large scale synoptic system,conventional physical quantity and satellite radar chart of the blizzard weather happened during Nov 10 to 11,2012 in Chaoyang County were analyzed.lt is summarized that the above blizzard was happened under the large scale of circulation situation. Furthermore,lhe mow-level convergence,upper-level divergence and strong ascending motion offered excellent dynamic condition for blizzard. Meanwhile ,an important cause of blizzard was came from the energy frontal zone and water vapor transport and convergence.
