It is shown that the albedo of melting particles may be more than the raindrops and snow spheres at c , x and ku - band . these results are in agreement with the conclusion observed by radar and given in literature . it demonstrates that the water - coated snow sphere model of melting particles is appropriate and practicable 应用该模型和涂层球的bhcoat法，计算了融化粒子的散射和反照率w _ 0 ；结果表明，在c 、 x和ku波段，融化粒子的w _ 0要比雨滴和雪粒子的大，这与雷达观测和文献结果一致，表明了该模型是切实可用的。
First , in order to verify the correct of this retrieval month , by using the data of three - dimensional wind field , raininess field and temperature field that are output by mm5 numerical simulation , we climate the radial velocity field and echo intention field in the in - phase observation area of dual - doppler radar , then , on the base of the upwards retrieval theory and using the radial velocity field and echo intention field in the in - phase observation area of dual - doppler radar , we retrieve the atmospheric three - dimensional wind field 首先，为检验此种反演方法的可靠性，我们使用mm5数值模式输出的三维风场、雨强场、温度场等数据，分别模拟生成两部雷达同步观测区的径向速度场和回波强度场，然后根据以上的反演理论利用模拟的双多普勒天气雷达观测到的径向速度场和回波强度场反演出大气三维风场。
