Is artificial rainfall harmful to nature?

The harm of artificial rainfall to nature is that artificial rainfall changes the natural law of nature, and forcibly forces the rain that is going to fall to the south to the north, in addition, the rainfall is a catalyst for spreading to the clouds, silver iodide, which does not belong to natural water, and silver iodide will also produce pollution.

Artificial rainfall uses the physics of clouds and precipitation to cause cloud droplets or ice crystals to increase to a certain extent by spreading rainfall agents into the clouds, and then fall to the ground to form precipitation. Under certain conditions, the microphysical process of artificial cloud modification can make clouds that cannot precipitate naturally under certain conditions, 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.

The principle of artificial rainfall is to make the volume of water droplets in the cumulonimbus cloud larger and fall down, and the anti-aircraft artillery artificial rain is to shoot the cannonball containing silver iodide into the 4000 to 5000 meters above sea level with a large number of cumulonimbus clouds, and the silver iodide spreads at high altitude and becomes the condensation nucleus of the water droplets in the cloud, and the water droplets quickly condense around it to reach a certain volume and then land. When silver iodide is transported by artillery shells into the air, it diffuses into small particles that are difficult to distinguish with the naked eye.

Disadvantages of artificial rainfall:

1. Cause the number of suspended particles in the air to increase in a short period of time, causing air pollution in the short term, but most of them are harmless to the human body.

2. Artificial rainfall is easy to cause the greenhouse effect, because large-scale artificial rainfall requires the use of dry ice, and a large amount of greenhouse gases will be released in the process of dry ice formation.

3. It will cause silver iodide pollution, which is the main ingredient in artificial rainfall shells, and has a certain degree of microtoxicity, which will cause pollution.

In general, if a small amount of artificial rainfall is used, the impact on the environment is not very large, but it is still necessary to use artificial rainfall with caution.

Artificial rainfall is a type of rain that is triggered by the dispersal of catalysts such as silver iodide into clouds, and sometimes dry ice is used. While this pattern of rainfall can alleviate drought, it also comes with some potential harms:

1.Artificial rainfall changes the natural laws of nature. It forcibly diverts rainfall that should have fallen to other areas to areas where it is needed, which can have an impact on the balance of the ecosystem.

2.The catalysts used in artificial rainfall, such as silver iodide, are actually a polluting substance. These substances accumulate in clouds and can have negative effects on the environment and human health.

3.Dry ice (in solid form of carbon dioxide) is often used for artificial rainfall, but its emissions can also contribute to the greenhouse effect.

4.Artificial rainfall can interfere with weather patterns and thus affect the global climate.

5.Artificial rainfall can have a negative impact on aquatic organisms, as these organisms may react to unnatural water sources such as silver iodide.

Overall, while artificial rainfall can help solve drought problems, it can also adversely affect the natural environment. Therefore, when using artificial rainfall, it is necessary to carefully consider its pros and cons and take measures to reduce its possible negative effects as much as possible.

Clouds are formed by the condensation of water vapor; The thickness and height of the cloud are usually determined by the amount of water vapor in the cloud, the number of condensation nuclei, and the temperature in the cloud.

Generally speaking, the gelatinous state of water vapor in clouds is relatively stable, and it is not easy to produce precipitation, while artificial precipitation is enhanced.

It is to destroy this glue-like stable state. Usual artificial rainfall.

It is to disseminate the catalyst (silver iodide) in the medium and low cloud systems with relatively large cloud thickness by certain means.

So as to achieve the purpose of rainfall. First, increasing the number of condensation nuclei in the cloud is conducive to the collision and increase of water vapor particles.

The second is to change the temperature in the clouds, which favors disturbance and produces convection. The disturbance and convection in the clouds will be more conducive to the collision and increase of water vapor, and when the updraft in the air cannot withstand the floating of water vapor particles, rainfall will occur. Generally speaking, it is not very harmful, it has little impact on the environment, but it cannot be said that it has no impact at all, as long as it is not used frequently, it is no problem, so no country will often use artificial rainfall to disperse rain clouds, and it will only be used during severe dry seasons or when it is necessary to hold a large event!
