Why does artificial rain rain rain in some places and not in others?

Artificial precipitation, also known as artificial precipitation, according to the physical characteristics of different clouds, choose the right time, use aircraft, rockets, etc. to spread dry ice, silver iodide, salt powder and other catalysts into the clouds, promote cloud precipitation or increase precipitation.

If the clouds are not up to the conditions, it will naturally not be able to form rainfall.

Of course there are implications.

What you say makes a lot of sense, in fact, you have to make artificial rainfall, it is because the conditions for natural rainfall are not enough or insufficient, so you find a way to make it rain. The amount of water that evaporates into the air is relatively fixed under certain circumstances, just like a thunderstorm in summer, when it rains in one place, it doesn't rain in other places. Because the condensate in the air has been used up, it will naturally be gone anywhere else.

Impactful.

According to the law of conservation, the total amount of water is certain, and if you have it, the corresponding place is gone. (Not rigorous, but the truth is the same).

Artificial rain is actually dry ice rainfall, and its dry ice shells are all counted, so there is no need to worry about the impact on other places.

This is really there, and it is not a new technology, it has been out for almost 20 years, as early as August 2008, during the Beijing Olympic Games, it was done during the Beijing Olympic Games, during that time the Beijing-Tianjin-Tang and Hebei areas happened to be rainy for a long time, in order not to affect the normal progress of the Olympic Games, but also during the rehearsal of the opening ceremony, the Beijing Meteorological Department obtained the support of the army through the General Staff Department, and sent planes to spray chemicals over Beijing every day, which basically achieved the desired effect perfectly. At that time, even the suburbs of Beijing were raining heavily for three days, that is, it was not raining in the urban area of Beijing, at most it was a cloudy day, and the most serious thing was that there was a little drizzle, and even the ground was not completely wet.

Now more than ten years have passed, artificial rainfall, rain reduction, and even rain elimination technology has made a qualitative leap, but there is a technical problem that has not been solved, that is: no matter how artificial prevention, it is impossible to let the rain disappear out of thin air, it should always fall, but through manual intervention, let it go in advance, or push it back, or even disperse it to an inconsequential place to go down, but not let it not go down, this is a bit like the law of indestructibility of matter and conservation of energy, At the current pace of scientific development, I believe that this problem will still be solved in the near future.

Artificial rainfall uses the physical principles of clouds and precipitation to spread rainfall agents (salt powder, dry ice or silver iodide, etc.) into the clouds, so that cloud droplets or ice crystals increase to a certain extent and fall to the ground to form precipitation, also known as artificial precipitation. Methods of spreading include aircraft scattering in the clouds, anti-aircraft guns or rockets shooting silver iodide shells into the clouds**, and burning silver iodide flames on the ground. It is the most widely conducted weather modification experiment.

The microphysical process of artificially influencing clouds can make clouds that could not precipitate naturally under certain conditions be stimulated and precipitated, and can also make those clouds with more water and often able to precipitate naturally, improve the precipitation efficiency and increase the amount of precipitation. However, clouds that cannot be naturally precipitated have less water, so the economic value of artificial catalysis is limited.

According to the principle of precipitation formation in nature, artificial rainfall artificially supplements some necessary conditions for the formation of precipitation, and promotes the rapid condensation or collision of cloud droplets and increases into raindrops and falls to the ground.

Subheading: Artificial rain is the projection of silver iodide shells into the clouds by airplanes, anti-aircraft guns or rockets**, and the burning of silver iodide flames on the ground. It is an anti-aircraft gun specially developed for rainfall.

The contents of the shells are salt powder, dry ice, or silver iodide, etc.

According to the physical characteristics of different clouds, 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 precipitation 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.
