Global warming makes the ocean temperature rise slowly, and warm seawater can provide power for hurricanes passing through it, making it stronger. Hurricane Katrina was originally a category 1 hurricane, but it suddenly became a category 5 hurricane because it absorbed a lot of energy in the hot Gulf of Mexico.
For those experts who believe that there is a correlation between climate change and hurricanes, the most powerful scientific basis is the theory of hurricane dynamics. According to this theory, when the ocean temperature rises above 30℃, the hot and humid air near the ocean surface interacts with the cold air above, thus easily forming hurricanes.
Typhoon has at least the following benefits for human beings:
First, with the rapid growth of global population and the development of industry and agriculture, the demand for fresh water is expanding day by day, and the limited fresh water resources on land are unevenly distributed, so the problem of water shortage in the world is becoming more and more serious. However, tropical storms and typhoons have brought people abundant fresh water. Typhoon brings a lot of rainfall to the coast of China, the coast of the Sea of Japan, India, Southeast Asia and the southeastern United States, accounting for more than 1/4 of the total precipitation in these areas, which is of great significance to improving the fresh water supply and ecological environment in these areas.
Secondly, the tropical and subtropical areas near the equator have the longest sunshine time, and the dry heat is unbearable. If there is no typhoon to dissipate heat in these areas, it will be hotter there and the surface sand shortage will be more serious. At the same time, the cold zone will be colder and the temperate zone will disappear. China will not have a spring city like Kunming, nor will it have an evergreen Guangzhou, and "Beidacang" and Inner Mongolia grassland will also cease to exist.
Third, the maximum speed of a typhoon can reach more than 200 kilometers per hour, and its energy is equivalent to the energy released when 400 2000-ton hydrogen bombs explode. Wherever they go, they destroy everything. This huge energy can directly cause disasters to mankind, but it also keeps the earth in thermal balance and makes mankind live and work in peace and contentment.
Fourthly, in the process of typhoon formation and operation with huge energy, with the help of lightning, long chains of water molecules can be interrupted to form active short-chain water molecules. Living things on the earth can increase the vitality of life after inhaling these short-chain water molecules, thus making the earth's ecology continue to develop.
Fifth, typhoons can also increase fishing output. Every time a typhoon blows, it turns over the river, rolling up the nutrients in the river bottom and the sea, increasing the bait, attracting fish to gather near the water surface, and naturally increasing the catch.
3. More than one third of the oil fields near the Gulf of Mexico were forced to close. Seven refineries and an important crude oil export facility in the United States also had to be temporarily closed. The price of the New York Mercantile Exchange crude oil soared 4.67 dollars to 70.8 dollars a barrel at the opening on August 29th. In Atlanta, the price of gas stations is $5/gallon higher. On August 3 1, the Bush administration agreed to use the strategic oil reserve to help the seriously damaged crude oil processing plants resume production. On September 2, the International Energy Agency announced that all 26 member countries agreed to put 2 million barrels of crude oil into the market every day for 30 days to help solve the market tension caused by Hurricane Katrina. New york crude oil futures prices fell sharply that day.
