摘要
应用常规天气资料、卫星云图、多普勒雷达资料对2004年6月20日、2004年6月24日在河北境内发生的两次风暴天气进行了对比分析。分析表明:(1)速度场的涡旋分析与M产品的结合,可以从雷达资料中获得局地强风和冰雹预报的参考信息;(2)云图中圆形的云团强弱和雷达垂直积分液态含水量的大小,能够反映风暴的强弱。
In this paper, using routine weather data, satellite images and Doppler radar data, the two storms, which occurred on June 20th and June 24th in 2004 in Hebei province, were comparatively analyzed. The results indicate that the reference information about local strong wind and hail's forecasting can be obtained by combining vortex analysis with mesoscale cyclone products, and the intensity of round cloud on satellite images and the size of vertical integrated liquid from Doppler radar products reflect the intensity of storms.
