Talking about the sudden change of wind and temperature

On the first anniversary of Liangshan fire, Liaokuo Mountain caught fire again and forest fires occurred frequently. Why? This is mainly because the forest is extremely flammable and combustible, and it is easy to cause fires when the weather is dry. The fire source is also the leading factor of forest fires. Then why is it difficult to put out forest fires? First of all, we should know that a large number of facts show that forest fires can be prevented, combustible materials and fire sources can be controlled artificially, and fire weather can also be predicted and prevented. The main thing is to do a good job. Forest fires will probably not happen, so we can't just focus on fire fighting. We should focus on how to stop forest fires, because forest fires are difficult to put out. First of all, because most forest fires occur in mountainous areas, the terrain is rugged, the traffic is extremely inconvenient, and it is very difficult to put out the fire. The mountainous terrain greatly limits the activities of rescuers, and it is difficult for large fire extinguishing equipment to reach the fire site quickly. In mountainous areas, forest fires are prone to explosion, especially in steep slopes, grass ponds, ridges and other special dangerous terrain, which will greatly increase the risk of fire fighting. Secondly, the climatic and meteorological conditions in mountainous areas are quite complicated, and the wind direction between valleys changes very quickly, which has a great influence on the development of forest fires. Especially in the dry season, the mountainous area is easy to cause updraft, and with the influence of various cross-mountain airflow and eddy currents, the wind direction changes suddenly, making forest fires extremely difficult to put out. There is also the fact that forest fires are often very intense, with a wide range of influences. What is even more frightening is that forest fires often occur in hot season and dry season. In addition, some trees contain a lot of oil and accumulate a lot of combustible substances. In addition, fires often expand and spread rapidly with the help of wind, which is also the main reason why forest fires are difficult to put out.
