How did hurricanes form?

The cause of the hurricane:

1, Coriolis force

The formation of tropical cyclone (hurricane) is influenced by Coriolis force (earth rotation). The driving force of tropical cyclone movement is the pressure difference between a low-pressure center and the surrounding atmosphere. Under the pressure difference, the air in the surrounding atmosphere moves directionally to the low-pressure center, forming a rotating airflow, which rotates counterclockwise in the northern hemisphere and clockwise in the southern hemisphere, so that the low-pressure center can be maintained for a long time.

Step 2: Hot water

The warm seawater that causes the low pressure area on the sea surface is the key factor of hurricane formation.

Step 3 damage

Some scientists began to study whether the warming earth will bring more powerful and harmful tropical storms. Most meteorologists believe that the earth seems to be getting hotter and hotter. They think that carbon dioxide and so-called greenhouse gases in the atmosphere are warming the earth.

Hurricane prevention measures:

1, get ready in advance, stay away from the coast and hide in a solid bunker.

Hurricane warning is usually issued 24 hours before the possible arrival. At this time, it is necessary to strengthen doors and windows, roofs, and reserve drinking water, food, clothing, and lighting appliances.

3. Being far away from the seaside and the river bank will be seriously damaged, accompanied by floods and big waves; Staying here will endanger your life. If you travel at sea, put down the sail, seal the cabin, put away all tools and leave the area where the typhoon passes as soon as possible.

It is best to stay in a solid building or basement. If there is no strong building, hide in the hurricane shelter and don't forget to cut off the power in the house before leaving.

Don't walk when the hurricane strikes, which is very dangerous. If necessary, avoid the route that the hurricane is about to pass.
