A high-rise building suffered from lightning strikes for dozens of times a year

“Lightning will not hit the same house twice,” Chen said. In the past, city buildings were relatively low, and lightning had greater randomness. The probability of a typical house being hit by lightning was lower, but the probability of a high building being struck by lightning was lower. Much higher. The results of a joint study conducted by lightning researchers and the Guangdong Meteorological Bureau by researcher Lu Weitao of the Chinese Academy of Meteorological Sciences showed that after a high-rise building in Guangzhou was completed, the number of lightning strikes within a radius of 1 km nearby was 2.5 times that before completion, and the average lightning strike was The strength is 2.2 times before the completion.
The researchers also expanded the study area to a range of 200 kilometers by 200 kilometers. After discovering that the high-rise buildings in the area were completed, the regional average lightning intensity was 1.2 times that before the completion of the construction, and the proportion of over 2.2 times was only 0.2%. Based on various data, the credibility of the high-rise building causing the increase in the intensity of lightning strikes exceeds 99%.
Chen Wenwen also stated that although high buildings can cause an increase in the number of lightning strikes, people can be assured of personal safety as long as they are strictly in line with lightning protection standards. The safety of high buildings is also guaranteed. .
