Snow is made of what exactly snow is and what is snow

We all know that clouds are made up of many small water droplets and Xiaoice crystals, and raindrops and snowflakes are formed by the growth and growth of these small water droplets and Xiaoice crystals. So, how is snow formed? In a water cloud, the cloud droplets are all small droplets.

They mainly grow into raindrops by continuing to condense and colliding with each other. Ice clouds are made up of tiny ice crystals. When these Xiaoice crystals collide with each other, the surface of the ice crystals will heat up and melt somewhat, and they will stick to each other and freeze again.

This is repeated many times, and the ice crystals increase. In addition, there is also water vapor in the clouds, so the ice crystals can continue to grow by condensation. However, ice clouds are generally very high and not thick, where there is not much water vapor, and the growth of condensation is very slow, and there are not many opportunities for collisions with each other, so they cannot grow to a large size and form precipitation.

Even if precipitation is caused, it tends to evaporate on the way down and rarely reaches the ground. The most conducive to cloud growth is hybrid cloud. Hybrid clouds are made up of Xiaoice crystals and supercooled water droplets.

While a mass of air is said to be saturated with ice crystals, it is not yet saturated with water droplets. At this time, the water vapor in the cloud condenses on the surface of the ice crystals, but the supercooled water droplets are evaporating, and ice crystals are generated from the supercooled water droplets"Adsorption"The phenomenon of water vapour. In this case, the ice crystals grow quickly.

In addition, supercooled water is very unstable. As soon as you touch it, it freezes. Therefore, in a hybrid cloud, when supercooled water droplets collide with ice crystals, they freeze and stick to the surface of the ice crystals, causing them to grow rapidly.

When the Xiaoice crystals grow large enough to overcome the resistance and buoyancy of the air, they fall to the ground, which is called snowflakes. In early spring and late autumn, the air near the ground is above zero, but this layer of air is not thick and the temperature is not very high, so that the snowflakes will fall to the ground before they have time to melt completely. This is called a descent"Wet snow", or"Rain and snow fall together"。

This phenomenon is called "sleet" in meteorology. Beg.

Snow is a Xiaoice crystal, and it should be that the vapor in the sky is solidified into ice due to the cold, and the snow falls because of the cold air and the 'foil' of the atmosphere! Did you solve your doubt?

What kind of snow: 1. White snow.

2. White snow.

3. Icy snow.

4. White snow.

5. Light snow.

6. Pale snow.

7. Thick snow.

8. Beautiful snow.

9. Cold snow.

10. Snow in the sky.

11. Snow on the ground.

Interpretation: 1. The white crystals falling in the air, mostly hexagonal, are formed by the condensation of water vapor in the air layer when the temperature drops below 0 or when the temperature is cautious.

2. The color or brilliance is like a cigar made of white. Bright. Surname. Trembling and weighing wash away (shame, hatred, wrongdoing) shame. Hate. Illustrious. Wash. <

Snow is the natural phenomenon of water or ice condensing in the air and then falling, or snowflakes falling. Snow is a form of water in a solid state.

The water on the earth is constantly circulating, the water in the ocean and the ground is heated and evaporated into the sky, and this water vapor moves to other places with the wind, and when they encounter cold air, they form precipitation and return to the earth's surface.

There are two types of precipitation: one is liquid precipitation, which is rain; The other is solid precipitation, which is snow or hail, etc.

The atmosphere is precipitation that falls on the earth's surface in a solid form, which is called atmospheric solid precipitation. Snow is one of the most prevalent forms of solid precipitation in the atmosphere. Solid precipitation in the atmosphere is diverse, from beautiful snowflakes to hail, which can cause great damage, as well as snow graupel and ice particles that we don't often see.
