Where is the highest frequency of lightning weather in China?

Thunderstorm activities in China are mostly concentrated in South China, Southwest China and the central and eastern parts of the Qinghai-Tibet Plateau. The annual thunderstorm days exceed 70 days, and some provinces (regions) in Yunnan, Hainan and Guangxi exceed 100 days, which is equivalent to nearly 1/3 days of lightning activities in a year. It can be seen that Yunnan, Hainan and Guangxi are the places with the most thunderstorms in China. Moderate thunderstorm activities are mainly concentrated in the south of the Yangtze River, the eastern part of southwest China, Tibet, northern North China and parts of northwest China, with annual thunderstorm days ranging from 40 to 70 days. Thunderstorm activity in Northeast China, North China, Jianghuai, Huanghuai, Jianghan, the eastern part of Northwest China and the central and eastern Inner Mongolia is less, with an average of 20-40 days in the whole year, and less than 20 days in most parts of Northwest China and central and western Inner Mongolia.
