Characteristics of tornadoes.

Tornadoes are characterized by seasonality and timeliness, high-speed movement and small-scale influence, strong destructive power and randomness.

1, seasonal and temporal characteristics: tornadoes often occur in thunderstorm weather in summer, especially in the afternoon and evening. Cumulonimbus clouds and convective weather in summer provide favorable conditions for the formation of tornadoes, and their survival time is only a few minutes, and the longest is not more than a few hours. This rapid formation makes it very difficult to predict and prevent tornadoes.

2. High-speed movement, small-scale impact: the wind speed near the tornado center can reach 100 to 200m per second, which is quite amazing. Because its diameter is between ten meters and several hundred meters, its attack range is small, but its destructive power is great. Tornado's moving path is mostly straight, and its moving speed is relatively fast, ranging from 40 to 50 km/h to 100km/h at the earliest.

3. Strong destructive power and randomness: Tornadoes often pull up trees, overturn vehicles, destroy buildings, and sometimes suck people away, which is very harmful. Tornadoes are extremely destructive, but their location and time are random, so it is difficult to predict, which is also a major difficulty in tornado research.

4. Tornado is a natural weather phenomenon, which is a small-scale air vortex generated under strong unstable weather conditions. Its central wind power can reach 100 to 200m per second, and its lower diameter is between several meters and hundreds of meters. A particularly large tornado can reach 1km.
