A tornado occurred in Kaiyuan City, Liaoning Province. Why can't we predict tornadoes?

Mainly because the formation of tornadoes is very irregular.

Tornadoes and typhoons are completely different. The conditions for the two disasters to form tornadoes are harsh and simply not enough. Once all the conditions are met to form a tornado, it will only take a few seconds. It is impossible to make a prediction with today's scientific and technological level. We can only predict the probability, but no one can say for the regularity, so sometimes the predicted tornado may or may not happen.

Before the tornado, the atmospheric pressure will fluctuate greatly, and there will be a lot of updraft. In this case, it only takes about 10 seconds to form a tornado, and the tornado slowly begins to spread and escalate. When the tornado was fatal, it took less than a minute. Therefore, most tornadoes are just a small whirlwind when they first appear, and even the forecasting unit may not pay much attention to them.

China is not a place where tornadoes happen frequently. I have a friend who has lived in America for a long time. He works on an American farm. Most farms in the United States are in open areas, where tornadoes are frequent. There may be two or three tornadoes a month. Numerous animals and vehicles here were overturned and then smashed to the ground, which brought a lot of disasters and influences to local farmers.

The American Astronomical Weather Service can't do anything about tornadoes. There are some scenes in many movies, and we can see professionals chasing tornadoes in weather forecast cars. This is not a way to find excitement, but to learn as much as possible about tornadoes, hoping to find out the formation law of tornadoes and make accurate predictions. I think these people who follow tornadoes are really brave people, because the killing radius of tornadoes is very large, and they may be doomed if they are not careful.

However, it is precisely because of the existence of these brave people that we can have such a profound understanding of today's tornadoes. I hope that researchers can continue to work hard and design some equipment that can accurately predict tornadoes as soon as possible, so that we can avoid disasters.
