Typhoon benefits: In China's coastal areas, almost every summer and fall will be more or less subject to typhoons and therefore suffered no small loss of life and property. As a disastrous weather, can be said that the typhoon brought, no one would be that it expresses her liking. However, everything has a duality, typhoon was brought disaster to mankind, but if there is no typhoon, humanity will suffer even more. Research found that humans have at least the following typhoon several major benefits:

First, the typhoon was for the people of this tropical storm has brought abundant fresh water. Typhoon to the Chinese coast, the Sea of Japan coast, India, Southeast Asia and the southeastern United States has brought a lot of rain, total precipitation in these areas accounts for about 1 / 4 above, to improve the supply of fresh water in these areas and the ecological environment are very important significance.

Second, near the equator in tropical and subtropical regions affected by the longest duration of sunshine, dry heat unbearable, if there are no typhoons to disperse the heat in these areas, there will be more heat, the surface sandy waste will be more serious. At the same time would be colder boreal, temperate and will disappear. Kunming, China will not have such a Spring City, nor evergreen Guangzhou, "Peking University warehouses", Inner Mongolia grassland will no longer exist.

Third, the typhoon can reach a top speed of 200 km above, wherever he went, Cuikulaxiu. This is a lot of energy can cause a disaster to human beings, but also the whole way with this huge energy flow to maintain the heat balance of the earth, so that human beings live in peace and prosperous.

Fourth, the typhoon also increase fish production. Every time when the typhoon hit badly, will leap onto the bottom of the volume of nutrients, increase in bait to attract fish to gather near the water, catch the natural increase.

In addition to landing area, the typhoon caused severe storms and other disasters, but also have certain advantages.

According to statistics, the Southeast Asian countries including China and the United States, typhoon rainfall total rainfall in these areas accounts for about 1 / 4 of the above, so if there are no typhoons in agriculture in these countries the plight of unimaginable; In addition, typhoons and for regulating the Earth's heat to maintain thermal equilibrium is well deserving, well-known in tropical regions of solar radiation due to heat up, so they are the most hot weather, while the boreal regions the opposite. As the typhoon activity, heat was dispersed in the tropics to high latitudes, so that the heat be compensated for cold areas, if there is no typhoon will result in more and more hot weather in tropical regions, while more and more cold boreal regions, natural earth temperate zone ceases to exist, and many plants and animals will be difficult to adapt due to extinction will occur, it would be a very frightening scenario.

Typhoon Disaster: Typhoon is a highly destructive severe weather systems, but sometimes can play a useful role in the elimination of drought. Its harmfulness There are three major areas:

① winds. Maximum winds near the typhoon center is generally 8 or above.

② rainstorm. Typhoon is one of the strongest storm weather systems, and working in the areas through which the general can produce 150mm ~ 300mm rainfall, to produce a small number of typhoons and heavy rainfall of more than 1000mm. 1975 No. 3 typhoon in the upper reaches of the Huaihe heavy rain has created extreme rainstorms in mainland China, forming a Henan "75.8" big flood.

③ storm surges. Coastal waters can generate most typhoons by water, coastal Jiangsu Province, the largest increase of water up to 3m. "9608" and "9711" was storm surge, so that along the Yangtze River in Jiangsu Province along the coast appeared ultra-high tide of history.

Typhoon storms often bring about the weather, causing sea waves, a serious threat to navigational safety. After making landfall, to destroy crops, various types of construction facilities, etc., resulting in people's lives and property of the enormous losses.
