The difference between a tornado and a typhoon

Specific differences between tornadoes and typhoons:

1. Tornadoes are small-scale weather systems, while typhoons are large-scale weather systems.

2. Tornadoes can rotate clockwise or counterclockwise, while typhoons in the northern hemisphere can only rotate counterclockwise.

The life course of tornado is only a few hours, while that of typhoon is several days to ten days.

Tornado is more powerful and destructive than typhoon, but the damage range is small.

Tornado is the strongest vortex phenomenon in the atmosphere, which often occurs in thunderstorm weather in summer, especially in the afternoon and evening. Although the scope of influence is small, it is extremely destructive.

Tornadoes often pull up trees, overturn vehicles, destroy buildings and so on. They often destroy crops and tens of thousands of fruit trees instantly, interrupt traffic, collapse houses, and cause human and animal lives and economic losses.

Typhoons are classified as tropical cyclones in Asia-Pacific countries or regions north of the equator and west of international date line.

Extended data:

The formation of tornadoes can be divided into four stages:

(1) The instability of the atmosphere produces a strong updraft, which is further strengthened due to the influence of the maximum transit airflow in the rapids.

(2) Due to the interaction with the wind with shear speed and direction in the vertical direction, the updraft starts to rotate in the middle of the troposphere, forming a mesoscale cyclone.

(3) With the development and upward extension of mesoscale cyclone to the ground, it becomes thinner and stronger. At the same time, a small area to strengthen cooperation, that is, the primary tornado is formed inside the cyclone, and the same process of producing the cyclone forms the tornado core.

(4) The rotation in the tornado core is different from that in the cyclone, and its intensity is enough to make the tornado extend to the ground. When the developing vortex reaches the ground, the ground air pressure drops sharply and the ground wind speed rises sharply, forming a tornado.
