The development process of typhoon mangosteen;
At 8: 00 on September 7, 20 18, the Japan Meteorological Agency upgraded it to a tropical depression, and issued a gale warning to it at 2: 05 pm on the same day. At 9: 00 p.m. 15 p.m., Japan meteorological agency upgraded it to a tropical storm, gave it the international code 1822 and named it Mangosteen.
Typhoon Mangosteen landed from the northern Philippines at 9: 00/00/08 in the early morning of 20/00/05/00/40, and left the land near noon, blowing to the South China Sea at a speed of 25 kilometers per hour.
At 9: 30 on September 20 18 15, Typhoon Mangosteen moved into the northeast of the South China Sea. At 16, the center of Mangosteen was located in the northeast sea about 850 kilometers south-east of Yangjiang City, Guangdong Province, and moved to the north-north direction, continuing to approach the coast of Guangdong Province.
On September 20/KOOC-0/8/KOOC-0/6/KOOC-0/7, Typhoon Mangosteen No.22 (strong typhoon level) landed in Shanyan Town, Taishan, Guangdong Province, and the maximum wind force near the center at the time of landing was/KOOC-0/4 (45m/s, equivalent to/KOOC-0.
At 8: 00 on September 20 18, Japan Meteorological Agency determined that it had completely dissipated.
According to the forecast path of the extended data, the initial landing point of Mangosteen was located in the western coastal area of Zhanjiang. When it passed through the northern Philippines on September 20 18 15, the path shifted to the northeast, and the expected landing point was changed to near Maoming. According to September 20 18 16,
Zhang Ling, chief forecaster of the Central Meteorological Observatory, said that one reason why the landing point has been moving eastward is that the uncertainty of the subtropical high has an uncertain impact on the path of Mangosteen.
In addition, the mountainous terrain in the middle of Luzon Island in the northern Philippines has an impact on the structure of Mangosteen. After it entered the South China Sea, Mangosteen has a stage of center reorganization or structural adjustment, which also has an impact on its later migration to western Guangdong.
The north-south high-pressure ridge on the east side of the typhoon will provide a driving force for the typhoon to move northward, which is also a factor affecting the change of typhoon landing location.
