The whole process of raining? It s raining, how do you stop it?

In a water cloud, the cloud droplets are all small droplets. They are mainly increased by continuing to condense and colliding with each other. Therefore, in a water cloud, for the cloud droplet to increase to the size of a raindrop, the cloud first needs to be very thick, dense, and watery, so that it can continue to condense and grow; Secondly, there needs to be a strong vertical motion in the water cloud, so as to increase the chance of multiple collisions and merging.

In the thinner and more stable water clouds, the cloud droplets do not have enough opportunity to condense and merge and grow, and can only cause cloudy, cloudy skies, and little rain. The distribution of the size of the cloud droplets varies from one cloud to another, and the reason for the uneven size of the cloud droplets is the transfer of water vapor in the surrounding air and the evaporation of the cloud droplets. The factors that make the cloud droplets grow are the condensation process and the collision merger process, in the case of only condensation, the size of the cloud droplets is uniform, but due to the replenishment of water vapor, some cloud droplets grow, plus the result of the merger, the larger cloud droplets continue to grow and become larger into raindrops.

Raindrops fall by gravity, and when there is an updraft, an upward force is applied to the raindrops, slowing them down, and some small raindrops may be carried up. Only when the raindrops increase to a certain extent can they descend to the ground and form rainfall.

Rain is a natural sight in which water on Earth is exposed to sunlight and evaporates into the air as water vapor. When water vapour meets cold air at high altitude, it condenses into small water droplets. These small droplets are small, with a diameter of only millimeters and a maximum of millimeters.

They are small and light, held in the air by updrafts in the air. It was these small droplets of water that gathered together in the air to form clouds. For these small droplets to fall to the ground as raindrops, they would have to increase in size by more than 1 million times.

How does a small water droplet grow its size by more than 1 million times? It mainly relies on two means: one is the condensation and condensation increase, and the other is the collision and increase of cloud droplets.

In the early stages of raindrop formation, cloud droplets mainly rely on the continuous absorption of water vapor around the cloud body to condense and condense themselves. If the water and gas energy sources in the cloud are constantly replenished and the surface of the cloud droplets is often supersaturated, then this condensation process will continue, causing the cloud droplets to grow and become raindrops. However, sometimes the amount of moisture in the cloud contains a limited amount of rainfall, and in the same cloud, the supply of moisture is often in short supply, so that it is impossible to make each cloud drop increase into a larger raindrop, and some smaller cloud droplets have to be merged into the larger cloud droplets.

If water droplets and ice crystals coexist in the cloud, the process of condensation and bloom increase will be greatly accelerated. When the droplets in the cloud increase to a certain extent, due to the increasing size and weight of the large droplets, they will not only catch up with the slower small droplets in the process of descending, but will also "swallow" more small droplets and make themselves stronger. When the large cloud droplets grow larger and larger, and finally the air can no longer support them, they fall straight from the clouds to the ground, and it becomes the common rain of people.

If you want to stop the rain, the key is to let the moisture in the air quickly decrease, and there are currently two ways to eliminate artificial rain. The first is to carry out artificial rain enhancement operations on the upwind side of the target area, usually about 60-120 kilometers, so that the energy of the weather system can be accelerated and diffused, and at the same time, water droplets in the air will be formed quickly in advance, and land on the ground in advance, so that the rain will finish in advance. Second, in the upwind side of the target area, usually about 30-60 kilometers away, over-sow condensation nuclei into the clouds, so that the content of condensation nuclei reaches 3 to 5 times the precipitation standard.

In layman's terms, it is to let the rain "hold back".

These two methods are analogous, the former is like Dayu's method of water control: drainage, and the latter is like the method of water control: blockage.

However, regardless of the method, the impact of artificial rain removal is relatively limited. The precipitation weather process with small range and weak intensity will achieve relatively ideal results, but in the case of heavy precipitation weather process, the current technical means cannot achieve the effect of artificial rain dissipation.

There is no way around this, God is going to rain, if you can, hit the rain cannon more, and it will rain him down, and then he will not rain.

It's raining, and trying to stop the rain is basically something that can't be reversed by manpower. Because it rains in the sky, it is caused by too much water vapor in the clouds, which condenses into water droplets in the air and falls. There is no technology yet to control the rain.

It's raining, and there's no way to stop it. Because we personally don't have the ability to do this. Therefore, we should learn to look at natural phenomena correctly and not get entangled in them.

What to do when it rains, the rain stops, in fact, this person is artificially uncontrollable. Because in nature, human beings have no control. At present, it is really annoying to rain every day.

However, it may not rain as much in the coming days. Gradually, after a few days, it will gradually stop raining.

No one can control what the weather is doing yet, and if you don't want to see the rain, lock yourself in your room. When the rain stops, you can't see it.

How can it stop when it's raining, the sky is not beautiful. Man can't control it!

Rain is a natural phenomenon, and human beings can't control it, unless you use metaphysics.

Generally two or three hours, sometimes a day or two, moderate rain in spring, scientifically defined as 10 mm of precipitation in 24 hours, 5 15 mm of precipitation in 12 hours.

Millimeters of rain in one hour is a weather phenomenon that occurs in all climate zones.

Characteristics: The rain falls like a line, and the raindrops are not easy to distinguish; Falling hard ground splashes; The water accumulation in the depression is relatively fast; There was a rustling of rain on the roof.

It won't be long.

It won't take too long, it always comes quickly and urgently, and it goes very quickly and urgently. I have the impression that 2-3 hours usually pass.

Artificial rain is based on the physical characteristics of different clouds, choose the right time, use airplanes, rockets to sow dry ice, silver iodide, salt powder and other catalysts into the clouds, promote the rapid condensation of cloud droplets or touch and increase into raindrops, and fall to the ground into rain. Its purpose is to alleviate or alleviate drought in farmland, increase the irrigation or water supply capacity of reservoirs, and increase the amount of electricity generated.

Artificial precipitation, also known as artificial precipitation, refers to artificially supplementing certain necessary conditions for the formation of precipitation according to the principle of precipitation formation in nature, so as to promote the rapid condensation or collision and increase of cloud droplets into raindrops and fall to the ground. 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.

To cause precipitation or increase rain in clouds (clouds with a temperature higher than 0), hygroscopic particles such as salt powder and urea should be sprinkled in the clouds to promote the formation of large cloud droplets and lead to the formation or increase of precipitation. If cold clouds (clouds with a temperature below 0) are to be used, catalysts such as dry ice and silver iodide should be sown by airplanes, etc., to produce a large number of ice crystals, so that the density of ice crystals in the upper part of the cold cloud increases, and precipitation is promoted or increased.

Artificial rainfall operations can only obtain the results of increasing the required amount of water under certain natural cloud conditions, and the technical conditions cannot achieve artificial rainfall. Natural precipitation is highly variable and artificial precipitation tends to be small. It is difficult to distinguish between artificial precipitation enhancement and natural rainfall in a precipitation process.

Generally, it doesn't take too long, it always comes quickly and urgently, and it goes quickly and urgently. I have the impression that 2-3 hours usually pass. But there is a longer period of time. I think that to determine how long a thunderstorm lasts, it is better to look at satellite images on the Internet, which will be more accurate.
