Natural disasters caused by typhoons include: strong winds, heavy rains, mudslides, landslides, floods, etc.
The formation of typhoon:
Typhoon (typhoon) is a strong tropical cyclone (wind speed exceeding 32.6 meters/second) that occurs in the northwest Pacific and South China Sea. Strong tropical cyclones in the Atlantic Ocean or the eastern North Pacific are called hurricanes, that is to say, they are called typhoons in China, the Philippines, and Japan, and they are called hurricanes in the United States. The tropical sea surface is exposed to direct sunlight, which increases the temperature of the sea water, and the evaporation of the sea water provides sufficient water vapor. Water vapor condenses during the rise, releasing a large amount of latent heat, which promotes the further development of convection motion, causing the air pressure at sea level to drop, causing the surrounding warm and humid air to flow in to supplement it, and then rise again. This cycle forms a positive feedback, which is the second type of conditionally unstable (CISK) mechanism. On the vast sea surface with suitable conditions, the influence range of circulation will continue to expand, reaching hundreds to thousands of kilometers.
Due to the high-speed rotation of the earth from west to east, friction occurs between the airflow column and the earth's surface. Since the friction force is stronger the closer to the equator, this guides the airflow column to rotate counterclockwise (the southern hemisphere rotates clockwise). The earth's rotation speed is fast and the airflow column cannot keep up with the speed of the earth's rotation, causing it to appear to be moving westward. This forms what we now call typhoons and their paths.
