摘要
应用常规气象资料和NCEP再分析资料,对2018年1月岳阳市2次雨雪天气过程进行了对比分析。结果表明,1月24—31日过程比3—8日过程影响范围广、强度强,主要与水汽和动力条件存在差异有关,2次过程降水相态的差异与各层温度层结的差异有关,700 hPa温度层结是雨雪相态转换的关键因子,雷达资料分析能较好地反映雨雪量的强弱。
Using conventional meteorological data and NCEP reanalysis data,two rainy and snowy weather processes in Yueyang City in January 2018 were compared and analyzed.The results showed that the process from January 24 to 31 had a wider influence range and stronger intensity than the process from January 3 to 8,which was mainly related to the differences in water vapor and dynamic conditions.The difference in precipitation phase state between the two processes was related to the difference in temperature stratification of each layer.700 hPa temperature stratification was the key factor for the transformation of rain and snow phase state.Radar data analysis could better reflect the intensity of rain and snow.
