中文摘要: 使用北京地区1999~2001年5~9月XDD03A雷电资料,用雷暴日逐时闪电频数与相应雷达反射率因子叠加的方法,寻找对流天气闪电分布特征。根据闪电轨迹推断对流天气中小尺度系统活动。
中文关键词: 闪电特征,雷达,短时预报
Abstract:Based on XDD03A lightning data in Beijing from 1999 to 2001, the lightning distribution characteristics of convection are given with hourly lightning frequency of thunderstorm combined reflectivity factors. And therefore, meso-scale convections could be deduced based on lightning tracks.
