The basins of water that were poured out of the tall buildings were blown away during the descent. It's simple and straightforward to do a test. The water is descending at a rate of about 10 meters per second, which means that the wind speed is blowing at 10 meters per second for the water, even if you feel that there is no wind on the ground.
Rainfall is when clouds meet a cold air current, and the water vapor quickly forms small droplets of ice crystals. It forms water like water vapor meets a piece of glass.
One millimeter of rainfall indicates the accumulation of one millimeter of water on a plane without evaporation, loss, or infiltration. If it is calculated according to the area of one acre of land, it is equivalent to pouring cubic meters of water into one acre of land. One cubic meter of water weighs 1,000 kilograms, so 1 millimeter of rainfall is equivalent to pouring 667 kilograms of water into one acre of land.
Therefore, the water content in the cloud is very huge, and it is not surprising that it lasts. On the Philippine side of Vietnam, it can sometimes rain for months in a row, which is called a disaster.

This starts with the formation of rain, clouds are formed by water vapor, and the cold and humid air flow and the warm and humid air flow meet to produce rain, and this situation must have the participation of crystal nuclei, countless water molecules and crystal nuclei combine more and more to form larger ice particles, and water vapor becomes ice to be exothermic, preventing further combination, and when the temperature decreases again, it combines and falls again, and then melts to form rain.

There are two main factors in the amount of rain in different places, the first factor is the raw material of rain, that is, whether the water vapor is sufficient; The second factor is whether the conditions for turning water vapor into rain are met.
Because it is located by the sea, or surrounded by the ocean, the first condition is satisfied, and the second condition mainly depends on the movement of the atmosphere. In some places, the influence of the monsoon can cause several months of rain, such as the Indian subcontinent, where the annual southwest monsoon carries abundant water vapor from the Indian Ocean, but it is blocked by the Himalayas.

Why is it not continuous because of the acceleration due to gravity.
The landlord is in junior high school?
Generally speaking, high school students should be able to understand this truth.
This is the reason why the water coming out of the faucet will become thinner and thinner, and if the faucet is far from the ground, the water will be discontinuous when it lands.

There is wind, big brother, the falling process has been blowing away for so long.
How can there be no wind in the sky? Because the height from the ground is different, the temperature must be different, and the temperature difference will inevitably lead to different air pressure, and the difference in air pressure will inevitably produce gas flow, that is, air flow, and air flow will bring wind.

If you don't say you need to, then I won't be able to do it!!
Lasting... It is mainly affected by various weather systems, such as warm and humid airflows, cold air, and subtropical highs, which may cause rain, and the duration is determined by the time affected by these weather systems. I don't know how to send me a message, I'm generally **!

Hey, that rain is formed slowly, do you have to be able to form continuous water at once, hehe, actually, I want to be simpler and just like that,

It's so simple that elementary school students can understand it.
There is much water in the heavens.

Think about water pouring down from upstairs.
It will also spread out halfway.
It's because of the resistance of the air ...

Ah, you're asking a very mysterious question, and this is not something that can be explained in one sentence, but it is necessary to use physical methods to gradually analyze the quality and force of the components in the raindrops. Hehe, introduce you to this book, you are a talent who will understand hehe.

Because of the large amount of moisture in the air, rain will continue for a period of time because the buoyancy of the large water droplets in the clouds will balance their gravity, and the speed of rainfall is limited.
Another reason is that the cold and warm air masses are used as a result of each other's posture and slow use during rainfall, and the cold and warm air leakage masses will not disappear very early, and they can be replenished by the back source, so the rain will not end soon.
In order to solve this puzzle, Professor Hu Lide of the Georgia Institute of Technology in the United States, in collaboration with the US Centers for Disease Control, conducted high-speed cameras of mosquitoes flying in the rain in order to carefully observe the behavior of mosquitoes when they are hit by raindrops. >>>More
In fact, celebrities are not as rich and happy as you think, but they are still better than our working class! Because the appearance fee and salary of celebrities are very high, they are much higher than those of us working class and higher than ordinary artists. As for why their income is so high, there is a question of value here, the appearance fee is high, the ticket price is high, and people are still flocking to it, the aura of idols makes their ** always a big hit and a sale, and generally the most closely related to celebrities is the economic company, which you will know if you often watch entertainment news. >>>More
Compared to air, water is a good conductor of heat. The body is exposed to air, and heat** is the body's production of heat and radiation, including sunlight. In this case, even if the air temperature is lower than the body temperature, it will still feel hot if the heat transfer speed between the air and the air is not enough. >>>More
Song Hye Kyo once revealed her little secret of maintenance: "I will apply whitening ** every day, and rub whitening essence frequently, because these nutrients can accelerate **metabolism, enhance ** own resistance, remove the dull yellow all day long, and restore ** fair and ruddy." In addition, every two weeks, Song Hye Kyo will also use eggs and honey to make her own whitening**, determined to carry out the snow-like complexion to the end.
Huang Duoduo is actually a child that everyone is very familiar with, she is Huang Lei's daughter, since she appeared in "Where Are You Going, Dad" a few years ago, she has been loved by everyone, and he has always made many people feel very envious and liked because of his excellence, and even caused criticism, and why is Huang Duoduo so goodIn fact, it is because his family conditions are related to the education of his parents. <> >>>More
