Typhoon Sura Route 9

The track of Typhoon Sura No.9 in 2023: Luzon-southern island of Taiwan Province Province-central Fujian-eastern Guangdong.

Typhoon Sura is located at 16.3 degrees north latitude and 124. 1 degree east longitude. The maximum wind force near the center is15 (48m/s), the lowest air pressure in the center is 945 hectopascals, the radius of the seven-level wind circle is 220-300km, and the radius of the ten-level wind circle is 80-65438+.

On August 28th, 2023, Sura will wander in the eastern part of Luzon Island, and turn to the northwest on August 29th, 2023. The intensity will increase again, and it will gradually approach the southern coast of Taiwan Province Island, and it will brush or land on the southern coast of Taiwan Province Island on the night of August 30, 2023, and then approach the coastal areas from central Fujian to eastern Guangdong.

Influenced by Sura, there were strong storms in Fujian, Zhejiang, Jiangxi and Taiwan Province provinces. In addition, "Sura" and Typhoon "Davi"No. 10 in August 2023 formed a double typhoon, which landed in the eastern coastal areas of China on the same day, causing strong winds and heavy rainfall in many coastal areas of China.

Typhoon characteristics

The four characteristics of Sura are: strong intensity, slow moving speed, strong local rain combined with southwest monsoon, long influence time and wide range. Another feature of Sura is its obvious combination with the southwest monsoon, which provides it with a steady stream of water vapor and energy. Compared with the isolated typhoon, the precipitation in this case is stronger and lasts longer.

Two days after the formation of Sura, it intensified into a typhoon, then intensified into a strong typhoon, and landed in Hualien, Taiwan with the intensity of a strong typhoon. In this season, the sea surface temperature in the western Pacific, especially east of the Philippines, is very high, which is especially suitable for the accumulation of typhoon energy. At the same time, the southwest monsoon transported a lot of water vapor around it, thus forming a relatively strong "Sura".

Sura moves very slowly. From August 28th, 2023, "Sura" was generated to 3 1, and its average moving speed was less than10 km/h. Even at 9: 00 on August 28th, 2023, it kept circling in the southeast of Taiwan Province Province. Because it was born in an environment with weak steering flow, and' David' prevented it from moving westward, its moving speed was very slow.
