摘要
本文利用成都市新津的风廓线雷达产品结合其它气象资料,对2011年7月3日08时～4日08时成都市区域暴雨个例进行跟踪监测和分析,初步探讨了强偏南风脉动、小尺度影响系统和强降水的关系,强对流云团的移动与强环境风的关系,垂直风速度与降水的关系;揭示了风廓线雷达水平风羽图和垂直风速度产品在强降水过程中的监测和短临预报的重要作用,为强降水开始时间、落区和强度的短临预报提供了一定的依据。
Combined with other meteorological data, a regional rainstorm case of Chengdu from 8：00, July 3rd tO 8：00, July 4th, 2011 was monitored and analyzed with wind profiler products from Xinjin, Chengdu. It discusses the relationship between strong southerly wind fluctuation, micro - scale system and heavy precipitation, also studies the relationship between the movement of strong convective cloud clusters and the strong environment wind, and the relationship between the vertical wind velocity and precipitation. This result reveals the importance of wind profiler＇ s horizontal wind barbs and vertical velocity prod- uct in the monitoring and short - term forecast of heavy precipitation, and provides evidence for short - term forecast on the beginning, the falling area and the intensity of heavy precipitation
