Are tornadoes and tornadoes just the difference in size?
A tornado is a strong wind vortex accompanied by a funnel-shaped cloud column rotating at high speed. The wind speed near the tornado center can reach 100 m/s to 200 m/s, with a maximum of 300 m/s, which is several times larger than the maximum wind speed near the typhoon center. The central air pressure is very low, generally as low as 400 hectopascals and as low as 200 hectopascals. It has a great sucking effect, which can suck the sea (lake) water away from the sea (lake) surface, form a water column, and then connect with the clouds, commonly known as "dragon water absorption". Because the air inside the tornado is extremely thin, the temperature drops sharply and the water vapor condenses rapidly, which is an important reason for the formation of funnel cloud column. The average diameter of the funnel cloud column is only about 250 meters. Tornadoes are produced in very unstable cumulonimbus clouds. Its formation is related to the strong rise of warm and humid air, the southward movement of cold air and topography. Its life history is short, usually lasting ten minutes to an hour or two, but its destructive power is amazing. It can uproot trees, blow down buildings or roll some ground objects into the air. There are tornadoes in Jiangsu Province almost every year, but the location has no obvious regularity. It usually appears in June and July, sometimes in early or middle August.
