What weather system does a typhoon belong to?

Typhoon is a kind of tropical cyclone, a low-pressure vortex that occurs on the surface of tropical or subtropical oceans, and a powerful and profound "tropical weather system". In China, tropical cyclones in the northwest Pacific are classified into six grades according to the maximum average wind speed near the center of the surface layer, and the winds near the center reach 12 or above, which are collectively called typhoons. Typhoons often bring strong winds, heavy rains and storm surges, which not only bring disasters to human beings, but also bring benefits to human beings. Typhoon has brought abundant fresh water resources to human beings, which is of great significance for improving fresh water supply and ecological environment. In addition, typhoons also keep the global cold and heat relatively balanced; The climate in the equatorial region is hot. If the typhoon does not disperse this heat, the tropics will be hotter, the frigid zone will be colder and the temperate zone will disappear from the earth.
