Problems solved by technology

Due to the discrete nature of lightning data, some peripheral lightning will affect the determination of the lightning center, and it is difficult to find the discharge center. Therefore, the current analysis methods of lightning law are more focused on the analysis of long-term lightning density, intensity, and lightning day. Have the ability to study the lightning discharge center and the law of lightning activity

Abstract

The invention discloses a method for realizing thunder and lightning space-time clustering, belonging to the technical field of lightning prevention. The method comprises the steps of: obtaining a thunder and lightning data information collection L to be clustered; dividing the thunder and lightning data information collection into a plurality of sub-collections Cn based on time attribute; performing spatial clustering analysis on each sub-collection Cn based on spatial attribute, and sequencing clustering results according the sequence of the time attribute; and storing the sequenced clustering results in a km1 file format, wherein n is not less than 1. The method for realizing thunder and lightning space-time clustering overcomes the technical problem that a discharge centre is difficult to make a decision due to discreteness of thunder and lightning data in the prior art (decision made by the thunder and lightning centre is affected by edge thunder and lightning), and has the characteristics of fast rate of convergence and high clustering accuracy.

Description

technical field [0001] The invention belongs to the technical field of lightning protection, in particular to a method for realizing lightning spatio-temporal clustering. Background technique [0002] Lightning is a natural discharge phenomenon. Due to its large current and high voltage, when lightning hits ground objects, it will cause great damage. Human beings have been conducting research on various lightning monitoring and lightning protection technologies. From the second half of the 1970s, the lightning location system began to appear in the United States to monitor the location of lightning occurrences. Since the 1990s, my country has built large-scale lightning location systems in meteorology, electric power and other industries. At present, lightning location technology is relatively mature, and humans can know the precise time and relatively precise location of a lightning strike through this system. [0003] The lightning positioning system can collect a large a...
