What does fire have to do with the weather?

Meteorological conditions are closely related to fire. The ignition point of various combustibles in nature depends on the change of meteorological conditions in the atmosphere. Such as humidity, temperature, precipitation, wind power and so on. It is generally believed that sunny, partly cloudy, high temperature and windy weather will reduce the air humidity and the water content of various combustibles, which is the most prone to fire.

Meteorological conditions affect fires in many ways. The key factor is air humidity. Generally, when the air humidity is less than 60%, there is a possibility of fire; The higher the temperature, the faster the evaporation rate of water in combustible materials, and the dry goods are easy to catch fire. The magnitude of wind power is also closely related to the occurrence of fire. Wind can not only dry articles and help to burn, but also make the fire source get sufficient oxygen supply and accelerate the burning after the fire occurs.

The frequency and severity of fire in winter and spring are the most serious, followed by autumn and summer.

Because of the close relationship between fire and meteorological conditions, meteorological scientists and technicians have developed fire risk forecast based on the influence of meteorological conditions. The purpose is to remind people by scientific means that the possibility of fire in high and strong grade time periods and areas is increasing, so we should be vigilant enough, strengthen the management of outdoor open fire and irregular use of fire, nip in the bud and minimize fire losses.
