克州地区一次持续性连阴雪过程的成因分析

摘要

利用数值预报产品和实况资料,诊断分析了2008年1月16—26日克州地区出现的罕见的持续性连阴雪天气过程。结果表明：有利的大气环流形势造成冷空气频繁,是此次降雪持续时间长、范围广、降雪量大的直接原因,而数值预报产品中的物理量的配置有利于降雪的形成和维持。%Using numerical forecast production and scene data,the weather process of rare continuous cloud and snow was analyzed diagnostically from January 16 to January 26 in 2008 years.The results showed that the direct cause of that duration time was longed,the range was wide,snowfall was more was frequent cold air caused by general circulation,the configuration of physical quantity of numerical forecast production was benefit on the formed and maintain of snowfall.
