| 摘 要： | 通过对强对流过程天气背景、物理量诊断分析,发现西南暖湿气流致使大气增温增湿和能量的积聚,大气处于不稳定状态;利用高频次、高分辨率的新一代天气雷达产品进一步分析,发现雷达基本反射率图像中显现出风暴的"穹窿"和BWER等结构特征;对流单体质心反射率强度、高度和冰雹概率均有陡增的现象.大气中的暧平流、高低空辐散、辐合场相配合导致垂直运动强烈发展并维持,促成了强对流天气过程.

| Abstract: | By diagnostic analysis of the observational elements during a thunderstorm process,it is found that south-west warm and wet flow with energy aggregation led to instability of the atmosphere.The radar data with higher frequency and fine resolution showed the details of vault and BWER structures of the thunderstorm.The intensity and latitude of reflectivity of center of mass for convective cell as well as hail probability have been found to increase suddenly.Warm air and convergence in low troposphere,diverge... |
