In a high - temperature environment, the moisture of vegetation evaporates rapidly, making it dry and flammable. Just like in a forest under the scorching sun, the moisture of grass, trees, and dead branches and leaves is severely lost. Moreover, high temperature can change the chemical properties of organic substances and produce more flammable components. After a fire breaks out, high temperature will enhance air convection, supply oxygen to the flame, and accelerate the spread of the fire.
Humidity cannot be ignored either. Low humidity reduces the water content of forest vegetation and combustibles, making them extremely flammable. A forest in a dry season is like a pile of dry firewood, and a single spark can cause a fire. Static electricity sparks generated by low humidity can also be a source of fire. High humidity, on the other hand, can absorb heat, reduce the combustion temperature, and decrease the concentration of combustible gases, thereby suppressing the fire.
Wind has a significant impact on forest fires. Wind supplies oxygen to the fire, making the fire more intense. It can also change the direction of the fire spread, increasing the difficulty of firefighting. The higher the wind speed, the faster the fire spreads and the wider the range. On windy days, sparks and burning debris can be blown to distant places and cause new fires.
Precipitation plays an obvious role in forest fires. Rainfall can increase the water content of vegetation and combustibles and reduce the risk of fire. Snowfall can cover combustibles and isolate oxygen, and the melting snow water can increase humidity. Conversely, a long - term lack of precipitation leads to drought, making the vegetation dry and fragile and greatly increasing the danger of fire. These meteorological factors are intertwined and affect the occurrence and development of forest fires.
The Forestry Weather Station can continuously and accurately monitor meteorological elements such as temperature, humidity, wind, and precipitation. Regarding temperature, the weather station can timely report high - temperature conditions, allowing relevant departments to know in advance the changes in the dryness and flammability of forest vegetation, thereby making a more accurate prediction of the possibility of forest fires. In terms of humidity monitoring, it can clearly show the level of air humidity. When the humidity drops to a critical value that may cause a fire, it can issue an early warning to remind of strengthening fire prevention measures. For wind monitoring, the weather station can obtain the wind direction and speed, which is crucial for predicting the direction and speed of fire spread. Firefighters can adjust the firefighting strategy according to the wind direction to avoid being surrounded by the fire. At the same time, they can also judge the possible range of the fire according to the wind speed. In terms of precipitation, the weather station can provide information such as the time and amount of precipitation. After precipitation, the risk of forest fires is reduced, and the deployment of fire prevention resources can be adjusted appropriately. Moreover, the data collected by the weather station can also be used to build a more scientific forest fire prediction model. Through long - term data analysis and simulation, the prediction ability of the occurrence and development of forest fires can be further improved to better protect forest resources and the safety of surrounding residents.
