差分反演单多普勒速度水平风场

Difference method for retrieving wind field from single Doppler radar

通过数学推导 ,在一定假设条件下给出用径向风分量求解切向风分量的解析式 ,公式简洁 ,易于处理 ,通过数值模拟和个例分析说明这个算法简便易行 ,与传统的VAD技术相比 ,可以在更小的角度范围内获得水平风场的信息。

WT5BZ]A method of retrieving wind from single Doppler radar under local linear assumption is presented.Tangential velocity can be derived from radial velocities along azimuth.Numerical test and case study show that this method is easy to use and has reasonable accuracy.Compared to the traditional VAD method,it can retrieve horizontal wind in relatively small azimuth angle span.
