摘要
为了探索X波段双偏振雷达产品在兴安盟人影作业和效果分析中的作用,文章利用人影基地的X波段双偏振雷达产品,结合713雷达、高空、地面观测资料,分析2020-06-20的降雹过程。初步确定了X波段双偏振雷达探测的有效范围;基本粒子HCL和45 dBZ回波顶高的波动对冰雹的识别有一定的指示作用。
In order to explore the role of X-band dual-polarization radar products in the shadow operation and effect analysis of Hinggan League, the hailstorm process on June 20,2020 was analyzed by combining the X-band dual-polarization radar products from the shadow base with 713 radar, upper air and ground observation data.The effective detection range of X-band dual polarization radar is preliminarily determined.The fluctuation of basic particle HCL and 45 dBZ echo top height can indicate hail identification.
