Judgment about thunderstorms position, moving direction and the path based on networking atmosphere electric-field monitors data

The extensive use of networking atmosphere electric-field monitors solved the problem that the single-station electric-field monitor exists such as the low warning success rate, the difficulty to master warning time, the difficulty to predict the direction of approaching thunderstorms and other issues in lightning monitoring and warning. In this paper, we dealt with networking atmosphere electric-field data. In order to use a minimum configuration of atmospheric electric-field monitor, we used the genetic algorithm and the bipolar model of thunderstorm clouds on the basis of existing research results, the two methods and the atmospheric electric-field data are used to calculate the height of thunderstorm cloud, the amount of charge and the distance to each station between thunderstorm, then the distance is reused to work out location, overlapping the position of each time, the direction and the path of thunderstorm can also be obtained. We selected typical thunderstorm weather in Shanxi 2013, and used a radar echo data for validation. The results show that three-point positioning method and genetic algorithm have accuracy in locating thunderstorms center and monitoring the movement path.
