What are the main hazards of typhoons?

Typhoon is a very destructive and disastrous weather system, but sometimes it can also play a beneficial role in eliminating drought. Its harmfulness mainly has three aspects: 1. Strong wind. The maximum wind force near the typhoon center is generally above level 8.

2. rainstorm. Typhoons are one of the strongest rainstorm weather systems. In areas where typhoons pass through, they can generally produce 150mm to 300mm of rainfall, and a few typhoons can produce extremely heavy rains of more than 1,000mm. Typhoon No. 3 in 1975 produced extremely heavy rains in the upper reaches of the Huaihe River, creating the extreme heavy rains in mainland China and forming the "75.8" flood in Henan.

3. Storm surge. Generally, typhoons can increase the water content of coastal seawater, and the maximum water increase along the coast of Jiangsu Province can reach 3m. Typhoons "9608" and "9711" increased water levels, causing unprecedented high tide levels along the rivers and coasts of Jiangsu Province.

Typhoon prevention and control: Strengthening the monitoring and forecasting of typhoons is an important measure to reduce typhoon disasters. The detection of typhoons mainly uses meteorological satellites. On the satellite cloud image, the existence and size of the typhoon can be clearly seen. Using meteorological satellite data, we can determine the location of the typhoon center, estimate the intensity of the typhoon, monitor the moving direction and speed of the typhoon, and the areas where violent storms occur, etc., which plays a key role in preventing and mitigating typhoon disasters. When a typhoon reaches the offshore sea, radar can also be used to monitor the movement of the typhoon. There are also meteorological forecasters who analyze the typhoon's movements, location and time of landfall based on various data obtained, and issue timely typhoon forecasts, typhoon warnings or emergency warnings, and serve the public through television, radio and other media. Governments at all levels provide decision-making basis, and issuing typhoon forecasts or emergency warnings is an important measure to reduce typhoon disasters.
