A regional heavy snow process appeared in the middle part of Henan on January 6,2001.

分析了2001年1月6日河南省中北部出现的区域性暴雪天气过程中天气系统的演变、物理量场,并对数值预报产品作出天气学解释。

Based on analysis of characteristics of atmospheric circulation and physical quantity fields on each layer,as well as hourly satellite images,the causes of a heavy snowstorm process in mountainous region of south Ningxia from 17to 18 October in 2002 was studied.

在分析大气环流及其诸层物理量场特征基础上,结合逐时卫星云图资料对2002年10月17～18日宁夏南部山区一次大暴雪天气过程成因进行了探讨,发现此次暴雪中低层存在着较明显的3股气流的共同作用,指出低涡及暖式切变线是本次过程重要的天气影响系统,降水水汽主要来自于低层输入,同时分析还表明宁夏强降雪也具有中小尺度特征。

Based on analysis of characteristics of atmospheric circulation and physical parameter field on each layer,and analysis of hourly digital satellite image data,a heavy snowstorm process that occurred in Ningxia Guyuan during 17-18 October in 2002 was studied.

在分析了大气环流及其诸层物理量场特征基础上,结合逐时卫星云图资料对2002年10月17日～18日宁夏固原一次大暴雪天气过程成因进行了探讨,发现此次暴雪中低层存在着较明显的三股气流的共同作用,指出低涡及暖式切变线是本次过程重要的天气影响系统,降水水汽主要来自于低层输入,同时分析还表明宁夏冬半年的强降水也具有的中小尺度特征。
