摘　　要：该文提出用单部多普勒天气雷达距离高度扫描（ＲＨＩ）的探测资料，从大气运动连续方程出发，在实际流场的二维假设下，反演雷达探测区域内的垂直剖面流场结构，通过个例试验表明，反演结果比较合理。该方法可供多普勒天气雷达探测研究应用。A method for estimating the vertical wind field from single Doppler radar Range-Height Indicator(RHI)is developed. By using the atmospheric continuous equation andthe two-dimensional supposition to real wind,the wind components perpendicular to theaxis of the radar beam within the radar vertical scanning plane are calculated.Severalexperiments show that the method is able to retrieve the vertical section of windstructure in the rain band reasonably,and it can be further applied to the study ofDoppler weather radar observations.
