风廓线雷达资料在一次强对流天气过程中的应用

摘要

通过分析2010年6月28日广州市南沙区强对流天气过程的风廓线雷达资料发现：风廓线雷达测得的温度廓线资料可以很直观地显示边界层逆温及高温区域随时间的变化；风廓线雷达产品（垂直速度和信号噪声比）能清楚地反映降水的开始、结束以及降水的强度；风廓线雷达可以很好的监测到低空急流的发生发展及水平风的垂直切变．对强对流天气的预报有一定参考意义。%Basing the wind profiler data of the convective weather process on June 28,2010 in Nansha District, Guangzhou City, the temperature profile data can display the thermal inversion of boundary layer and the high-temperature region change with time.The wind profiler product （vertical velocity and signal to noise ratio） can indicate the beginning, end and the strength of precipitation. The wind profiler is a good monitor to the occurrence and development of low-level jet and the vertical shear of horizontal wind.
