| 摘 要： | 该文改进了Qiu和Xu提出的由单个Doppler雷达探测的资料反演水平风场的简单共轭（simple adjoint）函数方法。其基本做法是将控制方程中的状态变量改用其时间距平量代替，并加入一待反演的方程误差项。利用1988年夏季在美国丹佛机场所作的一次下击暴流的双Doppler雷达观测试验资料对新方法作了检验，结果表明其对反演结果的改善是显著的。

| Abstract: | The simple conjugate method for retrieving the wind fields from single- Doppler dataproposed by Qiu and Xu (1992) is improved and tested using the Denyer airport microburstdata of summer 1988. In the upgraded method the temporal departures of radar velocity orreflectivity are used instead of the state variables and a retrieved error term is added into themodel equation. The test results show that the upgraded method improves the wind retrievalsignificantly. |
