摘要：

In order to study and find the spatio-temporal law of lightning activity, we comprehensively studied the lightning data in Foshan, Qingyuan, and Jiangmen regions of the Guangdong in lightning location system from 2008 to 2014, and discovered that the lightning activities had very strong cluster characteristics in time and spatial. Furthermore, we put forward a lightning spatio-temporal cluster characteristics analysis method based on spatio-temporal clustering, and analyzed the temporal and spatial clustering data from massive lightning data. We obtained the spatio-temporal law of lightning activity included in the lightning data to calculate and generate the lightning tracks, and pointed out the dominant directions of lightning activities and the lightning corridors leading to lightning faults frequently. Finally, we presented the optimal locations of the lightning towers for three cities. Foshan lightning towers had been put into operation in 2014, the lightning faults of Foshan area reduced from the previous annual average 25.5 times to 2 in 2014, the lightning towers do play a more obvious role in elimination of lightning. © 2016, High Voltage Engineering Editorial Department of CEPRI.
