| 摘 要： | 由近地面层辐合线（切变线）引发的局地暴雨是北京夏季一种较为常见的天气类型。利用常规气象资料、数值预报产品难以分析预报出引发局地暴雨的中小尺度系统、进而不能正确把握降雨出现的时间、落区和量值的大小。本文利用北京S波段多普勒天气雷达（CINRAD-SA）监测资料、风廓线仪、微波辐射计等新型探测资料,以及北京加密自动站观测资...

| Abstract: | The local heavy rainfall initiated by surface convergence line(wind shear line) is very common in summer in Beijing area.It is very difficult to forecast the time,zone and intensity of the rainfall from routine observation data and numerical weather prediction products. In this study,with the aid of S-band Doppler radar(CINRAD-SA),wind profilers,microwave radiometers,automatic weather stations,routine surface and rawinsonde observation data,a typical local heavy rainfall event was analyzed on fine-scale.The... |
