The Analysis of a Regional Rainstorm Using Doppler Radar Data

In the article,we analysised the rainstorm process using conventional information,encryption data,strength,speed and wind profile data of Doppler radar,discussed the atmospheric circulation system in the westing process of the subtropical high;revealed the different reasons caused two heavy precipitation(more than 10 mm per hour) and the possibility of small and medium-scale system existed,displayed the vertical distribution of the wind field over the stations in the rainstorm process and the close relationship between the transmission、strengthen of the level air-jet and the heavy precipitation,and then proved that the heavy precipitation was caused by the transmission and strengthen of the low-level jet.
