When forest fires occur, there is often no way to do it, so why not resort to artificial rainfall?

Because forest fires are so widespread, the use of artificial rainfall is too costly, and it is a waste of money, manpower and resources.

Artificial rainfall has many constraints and cannot be arbitrarily desired. It is necessary that the weather is hot and there is enough moisture in the air so that artificial rain can be used to extinguish the fire.

Because the fire was very large, black smoke was emitted, and the temperature was very high, there was no way to use artificial rainfall.

It's too simplistic to think. Artificial rainfall requires certain meteorological conditions. Not anytime and anywhere. Among them, water vapor conditions are the most important.

Artificial rain can extinguish it. Forest on fire-fighting equipment, vehicles can not enter. It will have to rain artificially. It's just as common if the rain is heavy. Now the forest is on fire, and the firefighting tools are not available.

Artificial rainfall does not fall as soon as it wants, it requires conditions. Artificial rainfall refers to the process of artificially supplementing certain necessary conditions for the formation of precipitation according to the principle of precipitation formation in nature, and promoting the rapid condensation or collision of cloud droplets and their increase into raindrops and fall to the ground. According to the physical characteristics of different clouds, the method is to choose the right time to use airplanes and rockets to sow dry ice, silver iodide, salt powder and other catalysts into the clouds, so as to make the clouds precipitate or increase the amount of precipitation, so as to relieve or alleviate the drought of farmland, increase the irrigation water or water supply capacity of reservoirs, or increase the amount of power generation.

This time, so many firefighters died in Daliangshan, Sichuan, and how many families were torn apart, which is really sad and sad. In peacetime, firefighters work hardest! I remember one year to travel to Zhangjiajie, a young tourist (Wuxi firefighters) followed our small team behind the fart, he said that he was on vacation to play, just from Fanjing Mountain, the work is very hard, maybe tomorrow will be gone!

Salute to the heroes, go all the way, no more fires in heaven! It is necessary to strictly investigate the perpetrators, do a good job in the investigation of potential safety hazards, and do a good job in publicity (especially the Qingming Festival is coming, many rural people still have the habit of burning paper money to sweep, which is very likely to cause mountain fires), so as to avoid similar accidents from happening again! I think artificial rainfall takes time, the rainfall is small, and fires don't wait for anyone, so artificial rainfall should be far away and water can't save close
