Is typhoon a normal weather phenomenon or a natural disaster?

Typhoon itself is a normal weather phenomenon. However, the strong winds and heavy rains brought by typhoons are natural disasters. The definition of disaster is an accident that threatens the safety of human life and property. If the typhoon does not cause loss of people and property, it is not a disaster but a normal weather phenomenon, but most typhoons will cause some losses, so they are called natural disasters. Of course, essence cannot be confused.

Natural disasters refer to natural phenomena that endanger human survival or destroy human living environment, including drought, high temperature, low temperature, cold wave, flood, flash flood, typhoon, tornado, fire whirlwind, hail, wind hail, frost, rainstorm, blizzard, freezing rain, fog, gale, ice, haze, smog, earthquake, tsunami, debris flow, floating dust and sand blowing. Under certain weather conditions, there are many observable physical phenomena in the atmosphere and on the ground. In the Standard for Surface Meteorological Observation compiled by China Meteorological Bureau, these observable physical phenomena are divided into precipitation, ground condensation, sight distance obstacle, lightning and other phenomena.

Typhoon is a disastrous weather system with strong destructive power. It comes and goes in a hurry, no more than eight or nine days, but it is extremely destructive. ? Typhoon releases much more energy than atomic bomb! The threat of typhoon comes from three ways of energy release: wind making, wave making and rainstorm. The maximum wind force near the typhoon center is generally above 8.

Typhoon is one of the strongest rainstorm weather systems. Generally, 1.50 mm ~ 300 mm rainfall can be generated, and a few typhoons can be generated. Heavy rain exceeding 1000mm; Typhoon can increase water in coastal waters, that is, storm surge phenomenon. Landing typhoons are generally in a mature stage. In addition to bringing serious disasters such as storms to the landing areas, typhoons also have certain benefits. According to statistics, typhoon rainfall accounts for more than a quarter of the total rainfall in Southeast Asian countries, including China and the United States.
