Causes of rain clouds, fog, dew, frost and hail, and the causes of clouds, rain, fog, dew, frost and

Rain: Water vapor liquefies into small water droplets or ice crystals melt into small water droplets that fall to the ground to become rain and snow: Ice crystals formed by water vapor condense fall to the ground.

Clouds: small droplets or crystals of Xiaoice formed by water vapor liquefied floating in the airFog: water vapor liquefifies into small water droplets on the groundFloats near the ground Dew: Water vapor liquefies into small water droplets on plants on the ground.

Frost: Xiaoice crystals formed by water vapor attach to the ground or plantsHail: As the water vapor in the cloud gathers, rain can be formed, and if cold air is encountered during the rainfall, hail will be formed.

Analysis: The water in the ocean, lake, plant surface, and soil is evaporating all the time, turning into water vapor and entering the atmosphere. Moist air containing water vapor rises upwards for some reason.

During the ascent process, as the surrounding air becomes thinner and thinner, the air pressure becomes lower and lower, and the volume of the rising air expands. When it expands, it dissipates its own heat, so the temperature of the rising air decreases. When the temperature decreases, the ability to contain water vapor becomes smaller and smaller, the saturated water vapor pressure decreases, the water vapor in the rising air quickly reaches a saturated state, and the temperature decreases again, and the excess water vapor attaches to the condensation nucleus suspended in the air and becomes small water droplets.

If the temperature is lower than 0, the excess water vapor condenses into ice crystals or supercooled water droplets. They are gathered together, supported by updrafts, and float in the air as clouds that we can see.

Clouds made up of liquid water droplets, including supercooled water droplets, are called hydrogenic clouds. If there are conditions for the cloud droplets to increase into raindrops and make the raindrops have a certain rate of decline, then it is rain or drizzle that falls. Clouds made up of ice crystals are called cryogenic clouds, while clouds that are made up of water droplets (mainly supercooled water droplets) and ice crystals together are called hybrid clouds.

Ice crystals or snowflakes that fall from ice-forming clouds or mixed clouds fall into the air layer above 0, and after melting, they also become raindrops that fall to the ground, forming rainfall.

If we know that after evaporation, sublimation, condensation, and condensation, we can easily understand that I am dizzy, and the rest of us go to see the information, and the trouble is dead

Weather phenomena mainly include: rain, snow, clouds, wind, frost, dew, dust, hail, tornado, typhoon, cold wave, etc. The fundamental cause of its formation is the unevenness of solar radiation on the ground, and the direct cause is the movement of the atmosphere to create a large bend.

Due to the fact that the earth is an irregular ellipsoid, the sea and land are unevenly distributed, and the existence of the yellow and red brother Li Jiao, as well as the earth.

Clouds, rain, snow, hail, fog, dew, and frost are all members of the water family, and the sun shines on rivers, rivers, lakes, and seas to evaporate water, and the water vapor rises to a low temperature, liquefiing into small water droplets or condensing into Xiaoice crystals, forming white floating clouds. If cold air is encountered again, the small water droplets gradually increase into large water droplets, and the white clouds turn into black clouds. When the large droplets of water get heavier and heavier, overcoming the support of the updraft, and falling to the ground, this is the rain.

In winter, the altitude is colder, and the water vapor is cooled sharply and cooled down, directly condensing into hexagonal Xiaoice crystals - snowflakes, when the snowflakes fall, they combine with each other, from small to large into snow flakes or large snowflakes, at this time, it will fall goose feathers and heavy snow.

What does hail in the summer look like? It turns out that when the raindrops in the clouds encounter a violent rising air flow and are carried to a high altitude below 0, they liquefy into Xiaoice beads; When the airflow weakens, the Xiaoice beads fall; When the updraft containing water vapor increases again, the Xiaoice beads rise and increase again; Jumping up and down like this, the small Xiaoice beads may gradually become large hailstones and finally fall to the ground.

When there is a lot of water vapor near the ground and cold air, the water vapor will liquefy into small water droplets with the dust in the air as the core, which is called fog.

In summer, the ground is very hot and there is a lot of water vapor. When the temperature is low before dawn, water vapor condenses into dew on leaves, flowers and plants.

In the morning of winter, the temperature on the ground is particularly low, and the water vapor condenses into white frost on the ground when it is cold.
