Can tornadoes be predicted? How do meteorologists predict tornadoes?

Tornado is a destructive strong convective weather phenomenon, which usually occurs in thunderstorm weather. Under extremely unstable weather conditions, the concentrated energy release process in a small area caused by strong convective weather produces strong air vortex. Everywhere, trees and houses are overturned, vehicles are overturned or even rolled up, and EF 1 tornado can do it, while EF 1 above, tornadoes have 2, 3 and 0.

Tornadoes are divided into tornadoes and waterspouts, which are easy to distinguish. What happens on land is a tornado, and what happens on water is a waterspout. The area where tornadoes occur most frequently in the world is Florida and the south-central plains of the United States. Most tornadoes in the world are here, mostly in spring, followed by summer. There are as many as 1000 tornadoes here every year, which have caused great personal safety and property losses to the local area. It is precisely because of this that the United States realized the necessity of tornado warning as early as 65,438+0,880.

In Asia, tornado-prone areas are located in China, Japanese, Indian and Bangladeshi. In China, there are 70 tornadoes every year on average, mostly in summer thunderstorm weather. At about 5 pm on July 3rd, kaiyuan city, Tieling, Liaoning Province was suddenly hit by a tornado. Tornado was formed by the northeast cold vortex and the low pressure zone in front of Mongolian cyclone, and it was also related to the thunderstorm weather at that time. The specific reasons are being analyzed.

As a small-scale and sudden strong convective weather phenomenon, tornado is local but extremely destructive, so how to do a good job of early warning and forecasting is the most important work. However, the average number of tornadoes in China is less every year, so it is difficult to invest more resources to establish a forecasting system, but it is classified as a severe convective weather warning. But for the United States, it is particularly important to establish such a forecasting system.

Although there is only one word difference between early warning and prediction, they are worlds apart. Early warning is relatively easy, but forecasting is much more difficult. When a tornado occurs, it can give an early warning to the possible peripheral areas according to the wind force and direction of the tornado. This is an early warning. Forecasting is to forecast a tornado hours or days before it happens. This is a prediction.

More difficult to predict. As early as 1948, American meteorologists predicted the tornado, and predicted the tornado five days later, but the accuracy of the location and time was only higher than the guess. So far, there are no reliable measures to predict tornadoes, so the United States often has a group of special wind chasers. They chase the edge of the storm and get more information about tornadoes in order to establish a perfect tornado prediction network.
