What are the hazards of hurricanes?

1. Hurricane is one of the weather systems that bring heavy rain. There may be heavy rain in the area where the hurricane passes.

2. Hurricanes can increase water in coastal waters, and the maximum water increase in Jiangsu coastal areas can reach 3 meters.

3. Hurricanes often bring stormy weather when crossing the border, causing huge waves on the sea and seriously threatening the safety of navigation.

4. The storm surge after hurricane landing may destroy crops and various building facilities, causing great losses to people's lives and property.

5. The collapse of houses, glass fragments, collision of floating objects and falling from high altitude caused by hurricanes will all lead to various injuries, with the characteristics of high disability rate and high mortality rate.

Extended data

Hurricanes can be hundreds of kilometers in diameter, roaring through tropical oceans and occasionally landing in densely populated areas, resulting in one of the most destructive climates on earth. The rotation of the earth makes the wind on the ground rotate, producing a huge spiral storm.

After the temperature rises in summer, the warm ocean makes the humid air rise continuously, which makes the humid air above the ocean warm. On the surface of the ocean, more air flows in to replace the humid air, which warms up slowly and then rises. A powerful cycle is constantly running, and more and more air is sucked into the low-pressure center.

The air pressure in the center of the hurricane is very low, but the air pressure around it is very high. Usually, the atmosphere will flow directly to the low pressure area. Starting from the surrounding high pressure area, the Coriolis effect will shift the atmosphere to the right, so the atmosphere in all directions will shift to the right and hover around the low pressure area instead of flowing up and down directly. This will lead to strong rotation and strong spiral updraft.
