The invention discloses a method and a system for thunderstorm process restoring and thunder and lightning channel analysis. The system comprises a standard data information acquisition unit, a standard data information storage unit, a standard data information processing unit and a display unit, wherein the standard data information acquisition unit is used for obtaining thunder-and-lightning positioning standard data information within a certain period of time through inquiring of a preset data base; the standard data information storage unit is used for storing the obtained thunder and lightning positioning standard data information within the certain period of time through the inquiring of the preset data base; the standard data information processing unit is used for obtaining a directed line segment capable of achieving characterization of a thunderstorm process, and a thunder and lightning channel model according to the thunder and lightning positioning standard data information; the display unit is used for outputting the directed line segment capable of achieving the characterization of the thunderstorm process and the thunder and lightning channel model in a visualization mode or carrying out data dissemination on the directed line segment capable of achieving the characterization of the thunderstorm process and the thunder and lightning channel model. The method achieves restoring of the thunderstorm process, and achieves analysis of the area thunder and lightning channel through a great amount of accumulation, superposition and clustering analysis of data of the thunderstorm process.
