摘　　要：利用常规、加密自动气象站分析了辽宁省2007年3月4日暴雪过程的天气尺度系统。结果表明,该次暴雪过程受南北2支高空槽合并加强影响,配合地面气旋稳定东移北上,低空急流的建立有利于水汽的持续输送,同时中低层的切变线提供了较好的动力条件。Conventional and confiden- tial autonomous weather stations were used to analyze the synoptic scale system of the snow storm on March 4, 2007. The results showed that this snow storm was co-influenced by the merging south and north high-level troughs, and moved northeast with the combination of ground cyclone, the low-altitude jet flow was fa- vorable for the continued conveying of water vapor, and the middle-low level shear line provided excellent dynamic conditions.
