What weather phenomena are often accompanied by typhoons?

Typhoons are often accompanied by violent storms and storm surges.

Typhoons are tropical cyclones that develop strongly on tropical and subtropical oceans. The airflow easily condenses into clouds and causes rain during the rising process. The central wind force is above level 12, which generally brings violent storms and storm surges. While it brings disasters to mankind, it also brings benefits to mankind. Typhoons bring abundant freshwater resources to mankind, which is of great significance for improving freshwater supply and ecological environment. In addition, typhoons also maintain a relative balance of heat and cold in various parts of the world; the equatorial region has a hot climate. If typhoons had not dissipated this heat, the tropics would be hotter, the frigid zones would be colder, and the temperate zones would disappear from the earth.

Typhoon is a type of tropical cyclone. A tropical cyclone is a low-pressure vortex that occurs on the tropical or subtropical ocean. It is a powerful and deep "tropical weather system." China divides tropical cyclones in the northwest Pacific into six levels based on the maximum average wind power (wind speed) near the bottom center. Those with wind speeds of level 12 or above near the center are collectively called typhoons.
