单多普勒天气雷达反演中尺度气旋环流场的方法

Method of inverting mesocyclone circumfluence field with a single Doppler radar

给出具有 Rankine模式中尺度气旋的模拟的多普勒径向速度图 ,利用中尺度气旋近似轴对称性及径向速度几何关系和付氏转换 ,建立 GBVTD方法 ,定量分析模拟的中尺度气旋内部流场结构 ,并利用郑州 714CD多普勒天气雷达资料进行验证。

WT5BZ]This paper gives Doppler radar radial velocity pictures of Rankine model mesocyclone and describes a technique(GBVTD:Ground Based Velocity Track Display)which uses the ground based Doppler radar data to extract the primary circulation of a mesocyclone. The data of Zhengzhou Doppler radar radial velocity are used to test and verify the method. [WT5HZ]
