Typhoon and tropical storm generate and develop on the tropical ocean surface. The low-pressure system is called the tropical cyclone. Internationally, the intensity is determined by the maximum wind force near its center and classified: typhoon above level 12; strong tropical storm on level 10-11; tropical storm on level 8-9; tropical low pressure on level 8-9 . The low-pressure trough and the high-pressure ridge are fluctuating in the high-altitude westerly airflow. The trough corresponds to the trough of low pressure. The warm and humid air in front of the trough is active, the rainy and snowy weather, the cold air control behind the trough, and the wind cooling weather; the peak corresponds to the high-pressure ridge, and the sky is clear. .
