| 摘 要： | 以3D-Barnes方案插值的新一代天气雷达反射率因子等高平面资料,用垂直累积液态含水量的理论模式计算雹云单体在降雹过程中的VIL,再用MAX函数逐个提取最大VIL(简称:VILmax),采用统计和回归处理技术,对2004~2006年5~8月青藏高原东北侧局地雹云单体的VILmax与对应地面冰雹最大雹径(简称:Rmax)之间的关系进行详细分析。结果表明,青藏高原东北侧局地冰雹Rmax与对应单体VILmax之间存在明显的正相关关系。 |

| Abstract: | Based on constant altitude plan data,like reflectivity factor of China new generation weather radar which is interpolated with 3D-Barnes scheme,VIL(Vertically Integrated Liquid Water Content,shortened form: VIL) during hailing process of hailstone cell is calculated with its theoretical model,and the maximum of VIL(shortened form: VILmax) is identified by use of MAX function.With methods of statistic and regression equation,the relation of VILmax of hailstone cell with the maximal hail diameter of local hail on ground in the northeast Tibetan plateau from May to August of 2004~2006 is analyzed in detail.Results show that there is apparent direct correlativity of VILmax of hailstone cell with the maximal hail diameter on ground in the northeast Tibetan plateau. |
| Keywords: | hailstone cell vertically integrated liquid water content hail diameter discrimination northeast Tibetan Plateau |
