What benefits and harms does the typhoon bring? This is my homework... - -

Benefits of typhoons: In my country's coastal areas, typhoons occur to a greater or lesser extent almost every summer and autumn, resulting in considerable losses of life and property. As a type of disastrous weather, it can It is said that when it comes to typhoons, no one will express a favorable impression of them. However, everything has duality. Typhoons bring disasters to mankind, but if there were no typhoons, mankind would suffer even more. Scientific research has found that typhoons have at least the following effects on mankind: Big benefits: First, typhoons are tropical storms that bring abundant fresh water to people. Typhoons bring a lot of rain to the coast of China, the Sea of ??Japan, India, Southeast Asia, and the southeastern United States, accounting for about the total precipitation in these areas. More than 1/4 of the total is of great significance to improving the fresh water supply and ecological environment in these areas. Secondly, tropical and subtropical areas near the equator receive the longest sunshine hours and are unbearably dry and hot. If there are no typhoons to disperse these The heat in the region will be hotter, and the surface sand desert will be more serious. At the same time, the frigid zone will be colder, and the temperate zone will disappear. Our country will not have a spring city like Kunming, nor will there be Guangzhou, "Beidacang", and Inner Mongolia that are evergreen all year round. The grasslands will no longer exist. Third, the maximum speed of typhoons can reach more than 200 kilometers per hour, destroying everything they go. This huge energy can directly cause disasters to human beings, but it also relies on this huge energy flow to maintain the earth's stability. Thermal balance enables human beings to live and work in peace and contentment and continue to thrive. Fourth, typhoons can also increase fishing output. Whenever a typhoon strikes, the rivers and seas are turned upside down, and the nutrients at the bottom of the rivers and seas are rolled up, and the bait increases, attracting fish to gather near the water surface. The fish catch will naturally increase.

Typhoon disaster: Typhoon is a very destructive disastrous weather system, but sometimes it can also play a beneficial role in eliminating drought. Its hazards mainly include three aspects: ① Strong wind. The maximum wind force near the center of the typhoon is generally above level 8. ② Heavy rain. Typhoon is one of the strongest rainstorm weather systems. In the areas where the typhoon passes, it can generally produce 150mm to 300mm of rainfall, and a few typhoons can produce extremely heavy rainfall of more than 1000mm. Heavy rain. The extremely heavy rain produced by Typhoon No. 3 in the upper reaches of the Huaihe River in 1975 created the extreme heavy rain in mainland China and formed the "75.8" flood in Henan. ③Storm surge. Generally, typhoons can increase the water content of coastal seawater. Jiangsu Province The maximum water increase along the coast can reach 3m. Typhoons "9608" and "9711" increased the water, causing the rivers and coasts of Jiangsu Province to have unprecedented high tide levels. When typhoons pass through, they often bring violent storms and cause huge waves on the sea surface, seriously threatening navigation. Safety. After landing, crops, various construction facilities, etc. can be destroyed, causing huge losses to people's lives and property.
