In the past few days, Typhoon Xuanlano exploded with unexpected violence, from a thin cloud that could hang at any time, to suddenly becoming the global wind king so far this year. At 9 pm on August 30, the center of Xuanlannuo was located on the ocean about 1,200 kilometers east-southeast of Xiangshan, Zhejiang. The maximum wind force near the center exceeded level 17.

From the satellite cloud image, Xuan Lannuo was fine The small core cloud group, typhoon eye wall and the typhoon eye are distributed in highly regular concentric circles. The typhoon eye is like a compass drawing. In the dark eye, there are extremely strong downdrafts and high temperatures of more than 20 degrees. The brightness temperature of Genting is very similar to the top Atlantic hurricane Dorian in 2019.

Before the Xuanlannuo outbreak, the East China Sea and the ocean south of Japan were continuously controlled by the subtropical high and downdrafts. The scorching sun had been exposed to the sun for more than 60 days, and there was a large area of extremely warm sea areas above 30 degrees, with sea temperatures as high as , the thickness of warm water is the highest in history. It is this extraordinary subtropical high, high temperature and warm water that gives the Pacific Ocean at 27 degrees north latitude unprecedented energy, creating such a monster. Before Xuanlannuo, there had never been such a strong westbound typhoon at 27 degrees north latitude.
It can be said that in terms of intensity, Xuanlannuo is a typhoon that cannot be inferred using common sense. On the path, Xuan Lannuo will be even more incredible. It will first go south, then stop, and then decide its direction. Among them, the role of the subtropical high is generally stable, and the main variable lies in another typhoon embryo, the 98W we mentioned yesterday.

As we said yesterday, although 98W is far less powerful than Xuanlannuo, it also has two unique advantages. The first is that in the more southerly ocean, energy water vapor More than Xuan Lannuo, and the second is that its size is larger than Xuan Lannuo. Because of this, after it approaches Xuanlannuo, it may have an unexpected Fujiwara effect with the super typhoon. Generally speaking, the stronger 98W is, the harder it will be for Xuanlannuo to eat it, and the path will be further west.
Today, during the day on August 30, 98W strengthened beyond expectations. At one time, a dense core cloud area appeared, and the possibility of strengthening into Typhoon Meihua , No. 12 , increased. If the strengthening trend of 98W continues, Xuanlannuo may be closer to our country Taiwan Island . After the stagnation is over, it may also be closer to the coast of East China. The possibility of landing in our country cannot be completely ruled out.
In 2019, under the mutual exclusion effect of Typhoon Rosa, Super Typhoon Lekima finally entered the East China Sea and landed in Zhejiang, causing serious impact. Of course, Xuan Lannuo is completely different from Lekima, and the possibility of landing is much smaller. But with Xuanlannuo's strength and the later annexation of 98W of volume, even if it doesn't land and just enters the East China Sea, the strong winds and waves will be very impressive. We remind friends on the coast of East China to start paying attention to Xuanlannuo. It is a very unusual typhoon.
