What's the difference between tropical storms, hurricanes, tornadoes and typhoons?

1. Tropical storm: It developed from the pre-existing tropical depression disturbance.

2. Hurricane: The warm seawater that caused the low pressure area on the sea surface is the key factor for the formation of hurricane; ? Warm ocean surface, the seawater temperature is higher than 26.5℃.

3. Tornado: near-surface wind shear and obvious vertical motion or energy instability, and thunderstorm is an ideal environment to meet the above conditions; The low-intensity discharge in the atmosphere is similar to lightning and different from typhoon.

4. Typhoon: the sea surface water temperature is above 26.5℃; Initial disturbance of a positive vorticity; The shear of ambient wind in the vertical direction is very small; Low pressure or cloud disturbance is at least several latitudes from the equator.

Second, the characteristics are different.

1, tropical storm:? In the season when tropical cyclones are active, tropical depression often appears on the ocean surface at low latitudes, but only a few of them can develop into tropical storms.

2. Hurricane: There is an eye in the center of the hurricane. The smaller the eyes, the greater the destructive power.

3. Tornadoes: Tornadoes are usually extremely fast. It is not surprising that the wind speed is 100 m per second, even reaching more than 175 m per second, which is five or six times larger than the typhoon of 12.

4. Typhoon: strong and extremely destructive.

Third, the occurrence areas are different.

1, Tropical Storm: Tropical Ocean.

2. Hurricanes: Atlantic Ocean and Indian Ocean.

3. Tornadoes: Tornadoes can be found in tropical and temperate regions, including the inland of the United States, western Australia and the northeastern part of the Indian Peninsula.

4. Typhoon: On the tropical or subtropical ocean surface.
