提应用边界层风廓线雷达对天山中部巴音布鲁克2012年8月8日22：00到8月9日04：00的层状云降水过程进行探测试验研究。利用垂直速度功率谱数据计算得到谱参数，根据谱参数的变化特点确定了0℃层高度为1100～1900 m。并对0℃层以下600～1100 m进行了雨滴谱的反演，反演结果说明了中粒子和大粒子浓度的多少是引起回波强度大小的主要因素。由雨滴谱计算得到了此次降水过程的降水强度和液态水含量的时空演变图，在变化趋势上和回波强度是一致的，建立回波强度和降水强度的关系为：Z＝76．5I1．6。

Using the boundary layer wind profile radar (WPR),a stratiform cloud precipitation event was observed and studied,which occurred in Bayinbluke in the central part of Tianshan Mountain from 22:00 BT 8 August to 04:00 BT 9 August 2012.The spectral parameters were obtained by calculating the data of vertical velocity power spectrum.The height of 0℃ layer evaluated by the change characteristics of spec-tral parameters is from 1100 m to 1900 m.By analyzing raindrop size distributions from 600 m to 1100 m, it is found that different size reflectivity depends on the concentrations of mid-sized particles and large-sized particles.The tempol and spatial trends of rainfall intensity and water content evaluated by raindrop size distributions are the same as the trend of reflectivity evaluated by the power spectral density.By analyzing the relationship between raindrop intensity and reflectivity,the equation is established:Z= 76.5I1.6 .
