摘要
应用MICAPS常规气象资料、区域站加密降水资料、NCEP再分析资料,采用天气学分析和动力诊断的方法,对2022年2月13日张家口地区出现的1次降雪天气过程进行综合分析。结果表明:(1)此次降雪过程主要分为2个阶段,第一阶段是暖区内偏南暖湿气流影响下产生的降雪,第二阶段是受冷锋系统过境影产生的降雪。(2)此次降雪过程暖区降雪相对持续时间较长,锋区过境降雪持续时间短,总降雪量最大值偏南。
Using MICAPS conventional meteorological data,encrypted precipitation data from regional stations,and NCEP reanalysis data,a comprehensive analysis was conducted on a snowfall process that occurred in Zhangjiakou area on February 13,2022,using synoptic analysis and dynamic diagnosis methods.The results indicated that:(1)The snowfall process was mainly divided into two stages.The first stage was the snowfall generated under the influence of southward warm and humid airflow in the warm zone,and the first stage was the snowfall generated by the passing shadow of the cold front system.(2)The relative duration of snowfall in the warm zone during this snowfall process was longer,while the duration of snowfall passing through the front zone was shorter.The maximum total snowfall was southward.
