Method for predicting distribution of lightning strike points in mountainous area based on zero line

The invention discloses a method for predicting distribution of lightning points in a mountainous area based on a zero line. The method comprises the following steps: firstly, acquiring a real thunder image or video, identifying and extracting the real thunder image or video, and statistically fitting an angle difference and probability distribution function relationship; secondly, based on thunder and lightning development characteristics in mountain terrain, a concept of a zero line is provided, and the zero line is drawn by using a super-relaxation iteration method through a space electric field calculation method. And finally, combining a zero line with an angle difference probability distribution fitting function to establish a lightning channel model, changing the position of a pilot initial point, performing mass simulation and statistics to obtain a lightning strike point distribution histogram, and predicting lightning strike point distribution. The prediction method provided by the invention can pre
