| Abstract: | Based on the system structure and basic principle of atmospheric Wind Profiler and Radio acoustic sounding system(WPR) being introduced,observations by WPR are compare with those by the radiosonde.The evidence suggests that observations of WPR are authentic.Furthermore,convective characteristics and vertical structures of mesoscale precipitation from Meiyu front are analyzed with wind speed and wind direction observations of atmospheric wind profiler.Results also show that the vertical structure of wind detected by atmospheric wind profiler is better,it can real-time monitor vertical shear and convective characteristics of wind during mesoscale precipitation,and it can improve accuracy of the rainfall forecasting too. |
