Will there be wind in artificial rainfall? Will artificial rainfall affect the weather?

No, because the principle of artificial rainfall has little to do with the formation of wind. The principle of artificial rainfall is to make the water droplets in cumulonimbus clouds bigger and fall down. Anti-aircraft gun artificial rainfall is to shoot a shell containing silver iodide with a large number of cumulonimbus clouds at an altitude of 4000-5000 meters. Silver iodide diffuses in the air and becomes the condensation nucleus of water droplets in the cloud, and the water droplets quickly condense around it to a certain volume and then land. Artificial rainfall can't change air pressure, so it won't cause wind.

Will artificial rainfall lead to cooling?

No, artificial rainfall uses refrigerants such as dry ice to sow seeds at high altitude. The reason for the drop of ground temperature is not caused by dry ice, but by the heat absorption of rain when it rains. For cooling, artificial rainfall may have limited effect, and the ability of artificial rainfall or artificial precipitation enhancement is only a small range of time. For long-term high temperature weather, the effect will not be too great.

Principle of artificial rainfall

Artificial rainfall makes use of the physics principle of cloud and precipitation, and by sowing rainfall agent into the cloud, cloud droplets or ice crystals increase to a certain extent and fall to the ground to form precipitation. According to the physical characteristics of different clouds, the method is to choose the right time to spread dry ice, silver iodide, salt powder and other catalysts into the clouds by planes and rockets to make the clouds precipitation or increase precipitation, so as to alleviate or alleviate farmland drought, increase irrigation water or reservoir water supply capacity, or increase power generation water.

Is artificial rainfall a sublimation phenomenon?

Yes Artificial rainfall, by throwing dry ice into the sky, dry ice enters the clouds and directly becomes gas, which is a sublimation phenomenon. In the state change of matter, sublimation and sublimation are two special processes, which are the state change of matter directly between solid and gas without other states. So this has become an important criterion to distinguish between sublimation and sublimation.
