摘要: 旨在应用配料法和多种观测资料对冰雹天气进行分析,以提高强对流预报准确率。采用基于构成要素的预报方法(配料法),综合使用常规观测资料、风廓线资料、多普勒天气雷达资料等,对2015年 6月1日下午发生在葫芦岛地区的以冰雹为主的强对流天气进行分析。结果表明:辽宁处于东北冷涡控制下,高空急流,低层切变;午后地面升温,大气边界层充分混合,具有较强的不稳定条件;低层水汽幅合,强烈的深层垂直风切变,有利于高度组织化的超级单体风暴产生和发展。辽宁西部的探空特征影响显著,对午后天气变化有一定的指示意义。合理利用“配料法”的预报思路,结合常规观测资料,运用雷达外推产品,可以把冰雹预报时间提前数小时。

Abstract: In order to improve the prediction accuracy of strong convection, the ingredients method and multiple observation materials were used to analyze the hail weather. By using general observation data, wind profiler data, Doppler weather radar data etc., the authors adopted the forecast method (ingredients method) based on components, and analyzed severe hail which happened in the afternoon of June 1, 2015 in Huludao City. The results indicated that Liaoning Province was controlled by the northeast vortex. The upper level jet and the low level shear line were existed. The atmospheric boundary layer was fully mixed after ground heating in the afternoon, which provided a strong and unstable stratification. The low level vapor convergence and the strong deep vertical wind shear brought benefit to the emergence and development of the highly organized supercell storm. The sounding features of the west of Liaoning had significant effects, indicating the weather change in the afternoon. By fully using the ingredients method with general observation data, and applying radar extrapolation products, the hail can be forecasted few hours in advance.
