摘要
利用雷暴观测资料和闪电定位仪资料对囊谦地区雷暴特征进行了分析。结合雷暴天气个例分析了强雷暴天气闪电活动与各物理量参数的对应关系,通过对比分析发生在囊谦地区对流天气的单体个例与卫星云图的相关性,提取囊谦地区雷暴天气雷电临近预报的预警指标,建立了雷电预警方案,提高了雷电天气的可预报性,对囊谦地区的雷电临近预报有一定的指示意义。
In this paper,the characteristics of thunderstorms in Nangqian area are analyzed by using thunderstorm observation data and lightning locator data.The correspondence between lightning activity and various physical quantity parameters in severe thunderstorm weather is analyzed in combination with thunderstorm weather cases,and the correlation between individual cases of convective weather in Nangqian area and satellite cloud images is analyzed.The early warning indicators of thunderstorm nowcasting in Nangqian area are extracted,and a lightning warning scheme is established,which improves the predictability of thunderstorm weather,and has certain indicative significance for lightning nowcasting in Nangqian area.
