What factors will affect the moving path of typhoon?

The moving path of typhoon is mainly influenced by the atmospheric environment.

The driving forces that determine typhoon movement can be divided into internal force and external force. The internal force of typhoon is mainly caused by the geostrophic deflection force accompanied by the rotation, airflow convergence and upward movement of typhoon itself. The internal force of typhoon is directly proportional to the radius of typhoon, the convergence and upward movement of air in vortex and tangential wind, and inversely proportional to the latitude of typhoon center.

Under the action of simple internal force, the moving track of typhoon center is a complex cycloid composed of sine wave and cosine wave with different amplitudes and the same period. The external force of typhoon mainly includes pressure gradient force, geostrophic deflection force and friction of environment (average airflow).

Extended data:

In the western Pacific, typhoons have roughly three paths.

The first route is west. The typhoon entered the South China Sea through the Philippines or Balintang Strait and bashi channel, and landed on Hainan Island or Vietnam to the west, which had a great impact on China. The second route is the northwest route. The typhoon moved to the west-northwest direction and landed in Taiwan Province Province, then crossed the Taiwan Province Strait and landed in Fujian Province. This path is also called the landing path. The third is the turning path. The typhoon moved northwest from the east China sea in the Philippines, turned northeast near 25 N and moved to Japan.
