Typhoon Xuan Lannuo (Super Typhoon Level) was generated on the Northwest Pacific Ocean at 2 pm on August 28. After generation, it developed rapidly. In the early morning of the 30th, it was strengthened to a super typhoon level, becoming the first super typhoon this year.

In the next 4 to 5 days, "Xuan Lannuo" will still maintain the strength of the super typhoon level, with a maximum strength of more than 17 or more (62-70 meters/s).

Xinmin Evening News reporter learned from the emergency management department today that "Xuan Lannuo" is approaching the East China Sea quickly. It is expected to move into the southeast of the East China Sea on the night of September 3, and maintain super typhoon levels for a long time. , Bohai Sea and coastal areas may have a heavier impact.

The National Defense Office and Emergency Management Department pointed out that the typhoon "Xuan Lannuo" has a great intensity, which will maintain the super typhoon level for a long time, and the development trend in the later period will be complicated. Essence

The center of "Xuan Lannuo" at 2 pm is located on the northwest Pacific Ocean of about 990 kilometers southeast of Shanghai (25.4 degrees north latitude and 129.1 degrees east longitude), the maximum wind near the center is above 17 or above (62 meters/s), the lowest center is the lowest in the center The air pressure is 915 Baipa, and the seven -level wind ring radius is 220 to 230 kilometers.

Why is Xuan Lan Nuo "unique position

Show the word "V"?

Whether "Xuan Lannuo" can eventually land in my country still has suspense. In the future, it first moves stability towards the south of the west and continues to approach the coast of East my country in China; subsequently, or rushed northward in my country to the north, showing a unique "V" trend.

The main reason for the "Xuanlan Nuo" path may be that it may change its subtropical high pressure. At present, the increased cold air activity in the north has increased the intensity of the subtropical high pressure. In the later period, as the cold air moves eastward, it may open a "channel" in the area where the subtropical high -pressure control is controlled to break it into two parts. Therefore, the critical period of Typhoon "Xuan Lannuo" in the future depends on when this "channel" can be opened.

From the current forecast, from September 2nd to 3rd is the critical period of the "Xuanlan Nuo" path. The subtropical high pressure will break from this night to tomorrow. After that, "Xuan Lannuo" will stay in Taiwan for a period of time in Taiwan, and then turn north by the auxiliary high -pressure east section from September 2nd to 3rd.
