中文摘要: 文章选取2013—2015年洞庭湖区域的15次雷暴大风天气过程,根据天气形势配置将其分为以下4类:低层暖平流强迫类、斜压锋生类、准正压类及高层冷平流强迫类。其中低层暖平流强迫类根据中低层切变线北侧冷平流的强弱又可以分为:强冷暖平流强迫类、强暖平流强迫类和中间类。总结归纳各类雷暴大风过程开始前、影响阶段及过程结束的天气形势配置、雷达回波特征与预报着眼点,为短期、短时天气预报预警提供参考。
Abstract:Based on the synoptic environment analysis of 15 thunderstorm cases in the area of Dongting Lake from 2013 to 2015, the weather situation can be divided into the following categories: low level warm advection forcing category, baroclinic frontogenesis category, quasi barotropic category and upper cold advection forcing category. According to the strength of cold advection in the north of low level shear line, the low level warm advection forcing category can also be classified into strong cold and warm advection forcing, strong warm advection forcing and middle category. Summarizing the synoptic situation configuration characteristics of thunderstorms in different stages, the radar echo characteristics and the forecast focus could offer references for short range, short time and nowcasting weather forecasts.
