Why is thunder so scary these two days? Meteorologists should give some professional explanations. It was really scary.

Chengdu, Sichuan News Network, June 20th-This morning, a strong thunderstorm hit Chengdu. According to the data of Sichuan Meteorological Observatory, there were 165 and 438+0064 Thundurus lightning strikes in Chengdu, the highest in history.

By 8: 30 a.m. on the 20th, the thunderstorm caused the 16 10 kV distribution lines in the main urban area of Chengdu and 42 10 kV distribution lines in suburban counties to trip. Affected by the spatial distribution of lightning strikes, line faults are more obvious in the northwest of the city and suburban counties such as Chongzhou and Dayi.

From 02: 30 am on the 20th, Shuangliu Airport was hit by a thunderstorm again. This is the third consecutive day that Shuangliu Airport was hit by a thunderstorm, and the flight plan of Shuangliu Airport was disrupted for three consecutive days. In response to this situation, Shuangliu Airport issued an emergency warning message for large-scale flight delays.

There are several reasons for this strong thunderstorm weather process. First, since the beginning of this month, Chengdu has been in the southwest warm and humid airflow on the edge of subtropical high, which leads to the increase of urban temperature, high air humidity, weak wind and extremely unstable atmospheric stratification; It happened that a cold air was falling over Chengdu. Another important reason is related to the typhoon that landed on the coast of Guangdong yesterday. The typhoon moved northwest after landing, bringing abundant water vapor and atmospheric energy to Chengdu.

Under the comprehensive action of the above conditions, there is a strong upward movement over Chengdu, which leads to the super convergence of airflow and the formation of strong thunderstorm clouds. Due to the obstruction of subtropical high and typhoon, thunderstorm clouds have been moving back and forth over Chengdu, forming lightning and thunder.
