Thunderstorm risk early warning method and system and electronic equipment

The invention discloses a thunderstorm risk early warning method, which comprises the steps that an observation area is subjected to grid point processing, and each grid point can correspond to the position of a target enterprise; acquiring meteorological data in real time through a meteorological observation system; calculating an intrusion angle of the precipitation cloud cluster relative to the target enterprise according to the orientation and the moving direction of the precipitation cloud cluster; executing a corresponding rainstorm early warning level judgment process based on the distance, the intrusion angle, the radar echo intensity and the precipitation amount of the precipitation cloud cluster around the target enterprise to obtain a corresponding rainstorm early warning level, and issuing a corresponding rainstorm early warning to the target enterprise; and based on the distance of the precipitation cloud cluster around the target enterprise, the intrusion angle, the radar echo intensity, the lig
