中文摘要: 分析了近50年来内蒙古所发生的暴风雪天气的环流演变特点。指出在暴风雪过程中,大风、暴雪、强降温联合施虐,加剧了人畜的热损耗率,从而形成严重的冻害。高空存在强急流、强锋区、强辐散是促成蒙古气旋猛烈发展形成大风的主要原因,而低层华北沿海高脊的发展又为南方水汽北输提供了条件,它们共同促成了内蒙古暴风雪的形成。
中文关键词: 暴风雪，灾害特点，环流特征
Abstract:Firstly,the circulation evolution features of snowstorm in Inner Mongolia in last 50 years is analysed.It is pointed out that barber,heavy snow and severe detemperature do together damage to human and animals more seriously in company with freezing disaster.They are the main factors of disaster formation.Strong jet,stronger frontal zone and strong divergence in upper air along the coast of north China become beneficial factors of vapor travelling from south to north.These factors promoted the formation of snowstorm in Inner Mongolia.Lastly,several circulation features of snowstorms in Inner Mongolia are analysed.
