风廓线仪系统探测试验与应用

THE ATMOSPHERIC WIND PROFILER AND RADIO ACOUSTIC SOUNDING SYSTEM WITH ITS APPLICATIONS

在简述大气风廓线仪和电声探测系统结构及探测原理的基础上,对廓线仪探测资料与同步探空仪资料进行了对比,验证了风廓线仪资料的可信度,并应用风廓线资料分析了梅雨锋期间中尺度降水的对流特征和相关问题。结果表明:大气风廓线仪对水平风的垂直结构有较强的探测能力,能实时监测中尺度降水期间风的垂直切变和对流特征,有助于提高临近天气预报的精度,准确预报降水。

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.
