多种单多普勒雷达风场反演方法对比试验

Contrast Experiments on Methods for Retrieving Two-Dimensional Wind from Single-Doppler Radar Data

采用典型风场资料对 4种单多普勒天气雷达风场反演方法进行了对比试验 ,这4种方法是 VAP方法 ,涡度 -散度法 ,简单伴随函数方法 ,动力方程组求解方法。试验结果表明 ,不同风场应采用不同反演方法。

Four methods for retrieving two dimensional wind from single Doppler radar data were introducted, they are the VAP method, rotation divergence method, simple adjoint method,and the PAR method.Three experiments were conducted using simulated single Doppler radar data to compare the methods.It is shown that different methods have different results.The root mean square errors of the tangential velocity and angle also support the main results.
