摘要: 利用1971-2010年辽宁省锦州地区4个气象观测站的逐日最低气温资料,对影响锦州地区的寒潮气候特征、路径和环流形势进行了分析,并特别对2006-2010年的寒潮过程进行了天气分析.分析结果表明,锦州地区西部出现寒潮的次数要比南部和东北部多,且10月和11月为寒潮发生最密集的月份;锦州地区北部寒潮发生的时间比南部和东北部开始早,结束晚;年平均寒潮次数为2.6次,逐年寒潮次数呈下降趋势,这与当前全球气候变暖是相一致的;影响锦州地区的寒潮分为东北、西北、偏西路径,从影响强度上看,东北和西北路径较剧烈,降温幅度较偏西路径稍大;影响锦州地区寒潮天气的环流形势分为横槽型、冷涡型、一槽一脊型和小槽发展型,其中以横槽型最多;通过对比分析发现,寒潮暴发前1~2 d,锦州地区各观测站气温普遍回升6~8℃.

Abstract: Based on four meteorological station's daily data in Jinzhou from 1971 to 2010, climate characteristics, type and path of cold wave were analyzed, and in particular, the cold wave from 2006 to 2010 was analyzed. The results showed as followed: cold wave happened in Western part more than Southern and Northeastern, and the cold wave mostly happened in October and November;cold wave happened in Northern earlier than Southern and Northeastern,but ended later; cold wave happened 2.6 times every year, and the number of cold wave happened downward trend year by year, which was consistent with global warming trend ;the cold wave affecting the city was divided into Northeast, Northwest and West path, and judging from the impact strength, Northeast and Northwest path were more intense than the West path, and cooling rate was slightly larger than the West path ; cold wave happened in Jinzhou region was divided into transverse groove, cold vortex type, a trough a ridge and a small groove development, among them the transverse groove maximum;through comparative analysis, it was found that 1-2 days before the cold wave outbreak, the temoerature of Jinzhou region generally rose 6-8 ℃.
