应用1971—2008年气象观测资料,对内蒙古大雪天气过程进行普查,查找出大雪天气过程98次。根据700hPa环流形势特征的不同,将内蒙古大雪天气形势分为2类6型。弱冷空气类：这种类型大多和南支暖湿系统相联系而出现,以降雪天气为主,降雪量较大。根据影响系统的不同分为槽涡型、切变型、北槽南涡型。强冷空气类：这种类型大多和高空长波槽脊相联系而出现,由于冷空气主体东移,且锋区较强,因此在产生降雪的同时,有大风和降温天气出现,多为风雪寒潮天气过程。根据影响系统的不同分为蒙古低槽（涡）型、贝加尔湖低槽（涡）型、西来斜压槽型。从系统的垂直结构分析表明：弱冷空气类与强冷空气类大雪存在明显的不同,弱冷空气类整层暖湿上升运动明显,强冷空气类对流层中高层冷平流强,斜压性明显。文章最后总结了各型大雪天气的预报着眼点。

The great snow weather process was added up using observation data from 1971 to 2008 years in Inner Mongolia,and it appeared 98 times.According to the different of 700hPa circulation situation,the great snow weather situation was divided into two categories and six types.Weak cold air category which mostly associated with southwesterly warm-wet system appeared,and it took snowfall weather as the principal thing,the snowfall was more.According to different influence system,the great snow weather system was divided into trough vortex type,shear type,north trough south vortex type.Strong cold air category which mostly associated with upper air long wave trough vortex system appeared,because of the eastward-moving of cold air subject and stronger frontal zone,there were gale and reducing temperature weather at the same time produced snowfall,this type mostly was blizzard cold wave.According to different influence system,the great snow weather system was divided into Mongolia low trough type,Baikal low trough type,western barocline trough type.According to the analysis of systematic vertical structure,there were obvious different between strong cold air category and weak cold air category,the whole level warm-wet ascending motion of weak cold air category was obvious,the upper cold advection in troposphere of strong cold air category was strong,and it＇s baroclinicity was obvious.At last,the forecast focus of attention of every great snowfall weather were summarized.
