Is the wind damage serious after the Songyuan earthquake in Jilin Province?

After the earthquake in Songyuan, Jilin Province, the wind disaster occurred again, and many infrastructures were damaged.

May 28th, Songyuan, Jilin. At noon 12: 30, Songyuan was hit by a tornado after the earthquake, and the wind speed was very fast, which lasted for more than ten minutes. The car glass of the building was broken and the big tree with a thick bowl mouth was blown down.

On May 30th, Taipingchuan Town, Changling County, Songyuan was hit by a tornado again, and many infrastructures were damaged under strong wind.

Some netizens questioned whether it was normal for tornadoes to appear after the earthquake. Zhao Guangnan, deputy director of the Provincial Meteorological Observatory, said that there is no relationship between the two. The formation of tornado is determined by cold vortex, that is, low pressure system. "However, it is easy to have rainy weather after an earthquake."

Why is it easy to rain after an earthquake? Zhao Guangnan, deputy director of the Provincial Meteorological Observatory, said that from a meteorological point of view, there are two reasons:

1. During the earthquake, the huge energy stored underground will be released instantly, and the ground temperature will rise, which will help the ground moisture to evaporate into the air, and the water vapor content in the air will increase, making it easier to form rainfall.

2. During the earthquake, a lot of dust and tiny particles will float in the air, and the shock wave will "bomb" these dust into the clouds, so these dust will become condensation nuclei, and water vapor will attach to these condensation nuclei, and then they will collide and combine constantly. When the air can't be lifted, it will become raindrops.
