| 摘 要： | 本文利用边界层风廓线雷达提供的风场资料,对南京2009年7月6—7日的大暴雨过程中低空急流与强降水的关系进行了详细分析。结果表明风廓线雷达每小时的风场资料可以很好的揭示低空急流脉动的强度及向下扩展的程度与中小尺度强降水之间的密切关系,对强降水的出现及强度有一定的指示作用,可以为临近预报提供参考。

| Abstract: | Based on the data of boundary wind profiler,this paper makes a detailed analysis on the relationship between low level jet and severe precipitation during a rainstorm from 6th to 7th July 2009 in Nanjing.The results show that the hourly wind field data derived from wind profile radar can pretty reveal a close relation between the extent of downward expanding of low-level jet stream and meso-scale strong rainfall.This index is significant for forecasting magnitude and intense of heavy precipitation,which can... |
