Formation and Effect of Surface Convergence Line in Local Rainstorm Process of Beijing
北京局地暴雨过程中近地层辐合线的形成与作用

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...
