摘要: |
利用常规观测资料和NCEP1°×1°再分析资料,发现2007-2016年6~8月有8次区域性暴雨天气过程是由副高东退、引导高空槽东移的大尺度背景条件下,配合低层系统造成的,将其分类后得到三种类型:低涡槽型、高空槽气旋旋转型和高空槽低涡切变型;对每种类型的高空形势进行合成分析,找出了暴雨落区与高空系统、物理量配置之间的关系。 |

Abstract: |
By using conventional observation data and NCEP 1°×1°reanalysis data,there were eight regional rainstorms took place in the summer from 2007 to 2016, which were caused by high-level trough
movement and the lower system.There were three types after classification: Low vortex groove type,high-level trough rotary type and high-level trough low vortex shear type.A synthetic analysis was performed for each type of high altitude system.The relationship between rainstorm zone and altitude system and physical quantity configuration was found out. |
Key words: regional rainstorms; subtropical high; high altitude system; rain fall area |
