However, the moving paths of typhoons are varied, just like drifting. There are many reasons for the typhoon path, mainly because the typhoon is affected by complex atmospheric environment and other factors in the process of atmospheric movement.
Generally speaking, typhoons that affect China are mostly generated in the western Pacific Ocean east of the Philippines.
After the typhoon is generated from the east of the Philippines, if the basic airflow around it is weak, the typhoon will be affected by the subtropical high at high altitude, and the easterly airflow will guide the typhoon to move westward. That is, through the Philippine Islands, westward into the South China Sea of China, and all the way to Guangdong, Hainan Island or the west coast of Viet Nam. This is the so-called road to the west.
If a typhoon encounters a southerly wind from northwest to southeast after its formation, it will move from the east of the Philippines to the northwest under the guidance of this airflow, land in Taiwan Province Province via bashi channel, and then cross the Taiwan Province Strait to approach the east of Guangdong or the coastal areas of Fujian, and land in Taiwan Province, Fujian, Guangdong and other coastal areas. If the starting latitude of the typhoon is high, it will pass through the Ryukyu Islands, land in the coastal areas of Zhejiang, Shanghai and Jiangsu, and even reach Shandong and Liaoning. This is called the northwest moving path.
If a typhoon moves northwest after it is generated and is blocked by the western Pacific subtropical high or westerly trough at sea, it will turn northeast and move to the Korean Peninsula or Japan. This turning typhoon can be divided into three categories: turning eastward, transiting and turning westward. This is the so-called turning path This year's typhoon "Lark", which will land in Jiangsu, Zhejiang and Shanghai tomorrow, will move northeast to Japan, turn around in Japan and move west to the Yangtze River estuary.
The following is the moving path of this typhoon.
