Abstract

The invention discloses a thunderstorm cloud cluster identification method and system for a meteorological satellite cloud picture. The method and system performs disc picture data analysis, projection transformation, median filtering, multiple image segmentation, and thunderstorm cloud cluster automatic identification on satellite original data, performs spectrum characteristic analysis and texture characteristic analysis on the basis of cloud cluster clustering to finally obtain the coverage, the intensity, and the motion locus of the thunderstorm cloud cluster. The invention further provides a thunderstorm cloud cluster identification system for a meteorological satellite cloud picture so as to systematically, efficiently, and automatically execute the above method, rapidly process and respond to meteorological satellite cloud picture data at each time level and continuous time sections, identify the thunderstorm cloud clusters, track the development and change of the thunderstorm cloud cluster, and provide valid technical support for prediction and early warning of meteorological disasters.

Description

technical field [0001] The invention belongs to the technical field of meteorological monitoring, and in particular relates to a thunderstorm cloud identification method and system of meteorological satellite cloud images. Background technique [0002] Thunderstorms are a type of severe convective weather, usually accompanied by natural disasters such as lightning strikes, rainstorms, and hailstones. Accurate identification of the location and range of thunderstorm clouds, as well as tracking the movement path of clouds, can provide the correct trigger conditions and corresponding parameters for the start-up of downstream disaster sub-chains such as lightning strikes and storms, so as to ensure the safety of people's lives and the social economy. Construction provides security. Radar observation is the main means of monitoring thunderstorms, and the main methods include cross-correlation (TREC) method and single centroid method. These methods not only cannot accurately del...
