Why is there no artificial rainfall in some places where there is a great shortage of water?

Because artificial rainfall requires clouds in the sky to carry out, and there are few clouds in places where there is a shortage of water, there are places where there is a great shortage of water, but artificial rainfall is not carried out.

Artificial rainfall requires a lot of conditions, there must be an appropriate amount of clouds, if the clouds are not enough, there is no way to carry out artificial rainfall.

Because artificial rainfall also requires climatic conditions, and the cost of artificial rainfall is very high.

Yes.

The high temperature lasts for a long time, and it is difficult for arid areas to alleviate the drought through artificial rainfall, because artificial rainfall also requires some necessary conditions, and if the conditions are not met, artificial rainfall is difficult to succeed.

If this had been possible in arid areas, there would have been experiments in the desert long ago, and there would not have been such a devastation of the desert. However, everyone must pay attention to safety and take sun protection measures when going out.

In order to implement artificial rainfall, three basic conditions must be met: first, the water vapor of the clouds floating in the sky must be abundant enough, and secondly, the clouds must have an upward trend. The third point is that there is a condensation nucleus.

Only if these conditions are met at the same time, the local authorities will carry out this task neatly, so the staff must observe the weather conditions and choose the right weather for manual operation. The phenomenon of high spring temperatures in many parts of the south is painful. Therefore, in some places, when the conditions are right, rain is immediately followed, which can temporarily alleviate the dry situation.

In rural areas, there are large areas of planting land, and the land is dry without rain for a long time, and the seeds may lodging or even not grow rice, but the weather forecast does not show rain for a long time, so it can only be made out of thin air by artificial means. However, this rain did not last long, and in some areas it stopped after only a few minutes of rain.

Then there must be rain conditions! Say rain and say rain!

Artificial rain should also become rain clouds.

National or local issues.

That's a question...It's like a 90-year-old man taking Viagra....

The sand in the desert is relatively sparse, and if artificial rainfall occurs, it is easy to form swamps on the one hand, and artificial rainfall is a waste of water resources on the other hand.

The desert is sand, and if it rains artificially, it will cause sand erosion, which is not of much use.

Because it is useless, the sand absorbs water easily, and it will become very dry after the water falls.

Why is it that there is a drought in many places, but artificial rain cannot be used to rain? Knowledge grows.

We all know that with the development of science and technology, there are many places that can improve the local climate through artificial rainfall, but there are still many places that suffer from drought, why can't these places use artificial rainfall to improve the local climate? What would happen if hundreds or thousands of artificial rain missiles were launched directly into the clouds?

In fact, it is difficult for this kind of artificial rainfall to fundamentally change the local climate, and it is basically impossible to carry out artificial rainfall in extremely harsh environments such as deserts. In fact, artificial rainfall depends on changes in local cloud cover. If the clouds themselves lack rainfall conditions, it is difficult to achieve the effect of rainfall.

First of all, under today's technological conditions, the main way of artificial rainfall is to arrange combustion furnaces on the ground, use anti-aircraft guns and various rocket facilities to launch catalysts into the air, and use aircraft to disperse catalysts directly on the clouds. In the case of artificial rainfall, the equipment for extracting missiles from jadeite is generally not used, because the accuracy of the missile itself is very high, but because of its high cost, it is also a wasteful behavior, so it is generally not used.

Let's just say that in a certain area, we can fire hundreds of rain bombs directly from anti-aircraft guns. In fact, depending on the different cloud conditions at the time, there may be different results. If the local clouds have already started to rain, or are on the edge of the rainfall, it is a tool for this artificial rainfall, and it may only work, if there are no clouds in clear weather, this rain bomb may have no effect on the clouds, which is a waste.

This kind of long-term rainfall will not only bring huge flooding to the local area, but also cause various extreme weather conditions in a short period of time. The damage is immeasurable, so even in places where water is scarce, this method does not bring rainfall.

What is the principle of artificial rainfall? Why can't artificial rainfall be achieved in perennial dry areas?

Because some places do not meet the conditions for artificial rainfall, the clouds are too lacking in rain.

Artificial rainfall must have sufficient conditions. If there are clouds that are likely to rain, there are no clouds in the arid places.

If artificial rainfall is forced in arid areas, it will change the local environment.

Because the climate is too dry, the cost of artificial rainfall is too high to carry out.

This is probably because rainfall in arid places requires a lot of manpower and material resources.
