Recently, when the reporter interviewed the Typhoon and Marine Meteorological Forecasting Center of China Meteorological Bureau, Qian Chuanhai, director of the center, told the reporter that in 2009, 22 numbered tropical cyclones were generated in the northwest Pacific Ocean and the South China Sea, 5.4 fewer than in the same period of history, while 9 landed in China, 2.2 more than in the same period of history. The landing time was concentrated and the location was southerly, and nearly half of the landing typhoons had complicated paths. Among them, the number of typhoons generated in September is the largest, while the number of typhoons generated in August, which has the largest average number of typhoons for many years, is less.

Zhang Ling, a senior engineer of the Forecast Center, explained that during the landing typhoon in 2009, Swan, Morakot, Bama and lupit were characterized by complex paths and long life history, among which Bama lasted for half a month. The reasons for the complexity of these typhoon paths are closely related to the interaction between multiple vortices. The large area and strong intensity of the subtropical high in the western Pacific in 2009 are the main reasons for the small number of typhoons generated in the western Pacific and the South China Sea this year. In addition, from the end of May to the beginning of August, the South China Sea summer monsoon was more active than normal, which made six typhoons concentrated at this stage and all landed in China. During the South China Sea summer monsoon, the strong vertical wind shear in the waters near the South China Sea is the key reason for the structural asymmetry of typhoons affecting China this year.

Are the characteristics of typhoon formation in 2009 related to El Nino events? Zhang Ling explained that last year's El Nino state was special, but from the historical statistics of the number of typhoons generated in the western Pacific in El Nino year, in most cases, when the equatorial Middle East Pacific entered El Nino state, the number of typhoons generated in the western Pacific was small. The relationship between El Nino events in the equatorial Middle East Pacific and the number of typhoons in the western Pacific last year is basically consistent with the above statistical relationship, but the specific influencing mechanism needs further study.

In addition, the quasi-east-west intertropical convergence zone, which is thousands of kilometers long, appears in the western Pacific and South China Sea many times, providing a good atmospheric background for the interaction of multiple tropical cyclones on the same convergence zone. The interaction between multiple vortices makes the typhoon's path, speed and intensity complex and changeable, which makes it difficult to forecast the typhoon business in 2009.

2008 is a once-in-a-lifetime opportunity for fans of Typhoon Bar, young and old. Not to mention teenage dolls, even people in their 40 s and 50 s or even 70 s and 80 s want to see the King of the Wind, but the East is also good. Compared with them, in 2007, Sao Paulo was just a younger brother. In 2008, there were more storms landing on the mainland than in 2007. Worth watching by fans. Typhoon will still maintain a high intensity when landing, just like Sang Mei in 2006. Different from usual, many typhoons generally begin to weaken before approaching land, but in 2008, they will become stronger before approaching land, so they will pounce on land with high intensity, and they are "a group of desperate money-grabbing maniacs". Indo-China Peninsula and samurai countries are their stage. This is the western Pacific Ocean and the Great West, separated by an ancient American land. Whether it is the Caribbean island in the middle of the ocean or the Gulf of Mexico, they are the hometown of hurricanes. In 2008, they will return to their hometown as kings. On the other side of the great west, on the west coast of Europe, God may send them a beautiful hurricane princess or a handsome hurricane prince. Otherwise, Europeans will soon forget what hurricanes look like. The reliable landing site will probably be between southern France and northern Iberian Peninsula. Europeans may learn that neither hurricane princess nor hurricane prince can stand it. Whether in western Europe or south-central Europe, the last time they visited Europe was a hurricane, or June 5438 +2005 10.

The wind "Vince" trudged all the way, not far from Wan Li, and waded to the Iberian Peninsula, where he put out a "fire" and sent a long-awaited shower to people there. If "Vince" is an "angel", then the hurricane in 2008 is a big "devil" for Europeans. Even if it roars, the European continent will tremble three times.

Characteristics of Typhoon (Hurricane) in 2008:

First, the eyes of the typhoon in 2008 will generally be very small, which is the smallest and most compact in recent years, but it will not last long, nor will it last so long as it did in 2004.

Second, the "parallel imports" of typhoons in 2008 are the same as those in 2007, and there will be more 1 1, unlike 1997, but the number of typhoons reaching typhoon level is more than that in 2007. Most typhoons generally don't last long in the case of strong typhoons.

Third, although there were many typhoon parallel imports in 2008, several of them were extremely strong, and few were even unparalleled in history. Its sinister hiding place lies in its (1) big roof and wide coverage. (2) It not only carries rich water vapor, but also creates heavy rain, and its destructive ability of disturbing energy is even more terrible. (3) When approaching land, it presents terrible lethality. This is like eating "land" into its stomach, and the coastal areas are the hardest hit areas. The wise choice is to run faster and farther, but if you are slow, you will be bitten and eaten by it. That's terrible.

Fourth, the basic characteristics of the typhoon (hurricane) in 2008 are similar in both Thailand and Taiwan, and Asia and Europe and the United States, especially Central America and North America, should be more vigilant.
