htmlOn August 28, as the typhoon embryo 90W developed violently in the depths of the Western Pacific and experienced explosive intensification, the Japan Meteorological Agency urgently named it Xuanlanno, and Typhoon No. 11 Xuanlanno was "suddenly" generated. At noon on August 29, judging from the high-definition visible light satellite cloud images, the petite Typhoon Xuanlano began to rapidly intensify without any foreshadowing. The clouds near its center are tight, and the core circulation is extremely tight and the energy is extremely concentrated. The Central Meteorological Station has announced that it has developed into a severe tropical storm of level 10.

The forecast of the Central Meteorological Observatory pointed out that Typhoon Xuanlanno will continue to move westward in the next few days, approaching the ocean east of Ryukyu Islands - Taiwan, and its intensity will continue to increase. It may develop to typhoon level tonight, and after September 1, it may develop to strong typhoon level with wind power of 14 to 15.

Some supercomputer forecasts pointed out that Typhoon Xuanlano will rapidly intensify as it moves westward, especially when it reaches the Kuroshio near the Ryukyu Islands, where it will encounter an atmospheric environment more suitable for its development and a more With sufficient seawater heat, the intensity will continue to increase, and the central air pressure will drop to about 925 hPa, which will be equivalent to a super typhoon level. So far this year, there has been no super typhoon in the Western Pacific. The development trend of Typhoon Xuanlano means that it is likely to develop into the strongest "wind king" this year.

The forecast from the United States Joint Typhoon Warning Center also pointed out that Typhoon Xuanlanno will develop to a wind speed of 130 knots around September 1, which is equivalent to wind power above level 17. All signs show that Typhoon Xuanlanno will be very powerful in the later stage, and will expand the circulation when it approaches the Ryukyu Islands. It will no longer be as small as it is today, but will develop into a large and ferocious typhoon. .

In this way, it is very worthy of attention to where the typhoon Xuan Lannuo will go in the future with huge circulation and ferocious circulation. The current supercomputer ensemble prediction believes that because the activities of Typhoon Xuanlanno are in the adjustment cycle of the subtropical high pressure and the westerly belt , and are affected by multiple systems, the path will be very complicated, and the ensemble path has become a mess. . If you look carefully, you can actually notice that there is a divergence in the path prediction of Typhoon Xuanlano in the waters south of Japan. At this point, Typhoon Xuanlano may go directly north to Japan, but it is currently more likely to move south in the southwest direction. .

Why does this typhoon move toward the southwest? As Xuanlannuo intensified violently in the past two days, it began to be gradually guided by the mid-level and upper-level subtropical high - northeasterly winds on the south side of the South Asian high; and this subtropical high - south high combination is creating my country's record-breaking high temperature weather this summer , almost indestructible: the more Xuanlannuo intensifies, the stronger the upper-level northeasterly wind it is guided by, and the path becomes more westerly. In addition, there is the residual circulation of typhoon embryo 98W to the west of Xuanlannuo, which will pull Xuanlannuo further to the southwest through the interaction of two typhoons. After going back and forth like this, Xuan Lannuo later took the southwest path.

Walking southwest to the vicinity of the Ryukyu Islands will be the second critical point of Typhoon Xuanlanno. During this period, Typhoon Xuanlanno on the Kuroshio will develop from a small and exquisite storm to a storm in both strength and size. They can all be called "Big Mac" typhoons. But it is also during this period that the westerly belt and subtropical high pressure will undergo huge changes, causing the path of Typhoon Xuanlano to fluctuate violently. It may land in Taiwan-Fujian, stagnate offshore, move northward in the East China Sea, or turn northeast to attack. Appears on the ensemble forecast, and the later path diverges like a goddess scattering flowers. Overall, this is the typhoon with the most complicated path this year, and it also shows the characteristics of autumn typhoons.
