摘要
利用2002—2004年5—7月15次伴有低空急流暴雨天气过程的常规观测资料,分析了湖南汛期伴有低空急流的西风带暴雨过程。结果表明,湖南汛期暴雨可以分成低槽暴雨和切变线暴雨两类,切变线暴雨又可分为冷式切变线暴雨和暖式切变线暴雨;不同类型暴雨的雷达回波结构和特征具有明显的区别。
According to different weather patterns, the large-scale rain-storms accompanied with low-level jets in Hunan Province from May to July （ flood season ） in 2002--2004 are divided into two categories of trough and shear line rain-storms, while the latter includes warm and cold shear line rainstorms. And their radar echo features are investigated. It is shown that there were different echo structures and characters in different weather pattern rain-storms.
