Abstract: In order to improve technical services of lightning warning and protection, this paper used electric field meter to get real-time lightning occurrence and development of observational data. And this paper combined with radar, lightning positioning, satellite and other observations to track the lightning trajectory and electric field intensity. According to the exponential trend, this paper carried out systematic analysis of future trends and formatted a specific area of?? short-term warning of lightning to avoid and mitigate potential disasters and losses.
