| 摘 要： | 利用多普勒天气雷达提供的垂直积分液态水含量、回波顶高、风暴体积、体积含水量、反射率因子产品,以及回波面积和降水通量等,对2004年6月28日的一次人工防雹作业前后的有关参数变化进行了分析,对作业效果进行了检验。结果表明,云体的相关参数在作业后发生了显著变化,对流发展趋势得到减弱。选取合适的多普勒雷达产品进行综合分析,可以对人工影响天气作业效果进行检验,为建立以新一代天气雷达为基础的人工影响天气效果检验系统提供参考。

| Abstract: | The variations of the related parameters before and after a hail suppression operation on 28 June 2004 are analyzed by using the products of Doppler weather radar,such as vertically integrated liquid,echo tops,storm volume,volumetric water content,base reflectivity,echo area,etc.The effectiveness of the operation is evaluated.The results indicate that the related parameters of clouds changed obviously and the trend of convection growth was weaken after the operation.It is shown that through the comprehensive analysis of carefully selected Doppler weather radar products,the effectiveness evaluation of weather modification can be conducted,which provides reference for the establishment of the effectiveness evaluation system of weather modification based on the new generation Doppler weather radar. |
