中文摘要: 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。
Abstract: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.
