A tornado is very destructive. It will blow down trees, houses, street lights, etc., and sometimes cause casualties. The formation principle of tornado

The occurrence of tornadoes is a weather phenomenon caused by multiple factors, including airflow, wind shear, etc. First, the atmosphere will generate unstable energy under the influence of the convective system, and then generate updrafts. Then, the updraft will begin to rotate horizontally under the combined influence of wind speed and wind shear. The emergence of this phenomenon is based on the generation of "vertical vorticity".

After this, the convergent airflow will cause this rotating system to gradually enter the convective system, and the core of the tornado will be generated in the troposphere. Finally, under the influence of the downdraft, the core vortex will extend downward, causing the surface air pressure to drop significantly. Corresponding to the rapid drop in air pressure is the rapid increase in wind speed on the ground. At this point, a tornado forms. Huludao Tornado

On the afternoon of the 25th of this month, a tornado suddenly swept through Longgang District, Huludao City, Liaoning Province. Multiple communities in this area were hit by this tornado. . According to subsequent statistics, more than 50 houses were damaged by the sudden tornado, and many of them had their windows blown away. In addition, many trees in Longgang District were also uprooted by the tornado. In terms of casualties, one person was injured in this tornado. Regional distribution of tornadoes

According to relevant statistics, tornadoes are a global weather phenomenon. Currently, tornadoes have occurred in all continents except Antarctica. The country with the highest frequency of tornadoes is the United States in North America, followed by Canada, also in North America. As far as Asia is concerned, countries such as China, Japan, and India are all countries where tornadoes occur more frequently. On average, more than 70 tornadoes occur in China every year, with the occurrence time mainly concentrated in spring and summer, with July and August being the most frequent periods.

The tornado phenomenon in China mainly occurs in the plain areas in the central and eastern areas. Provinces such as Jiangsu, Anhui and Hubei are all tornado-prone areas. Tornadoes, like typhoons, have strong and weak winds. However, in terms of time, the duration of tornadoes is generally shorter, usually from a few minutes to more than ten minutes. Tornadoes are very destructive, and large tornadoes have the momentum to blow away everything. Therefore, when encountering a tornado, be sure to avoid dangerous houses, trees, street lights, billboards, etc. to prevent them from being smashed. In addition, do not stay in a car to prevent it from being blown away together with the car. When avoiding a tornado outdoors, be sure to run vertically in the direction of the tornado's movement.
