摘要
利用桃仙机场常规观测资料和NCEP再分析资料,统计对比分析了2000-2019年发生的初雷天气过程。通过发生初雷时伴随的降水的最大强度将初雷分为弱降水初雷(包含无降水)、中等降水强度初雷、强降水初雷三种类型。对上述三种类型的初雷从气候统计特征、形势场、物理量场包括水汽通量散度、温度平流、垂直速度、大气温湿场进行分析,对比总结这三类初雷的特征。
Using the routine observation data of Taoxian Airport and the NCEP reanalysis data,the statistical analysis of the first thunder weather process occurred in 2000-2019,the initial thunder is divided into the weak precipitation initial thunder by the maximum intensity of the precipitation accompanying the initial thunder(including no precipitation),moderate precipitation and strong precipitation.The above three types of initial mines are analyzed from the climate statistical characteristics,the situation field,the physical quantity field including the water vapor flux divergence,the temperature advection,the vertical velocity,and the large temperature wet field,and the characteristics of these three types of early lightning are compared and summarized.
