How are clouds formed?

The clouds in the sky are sometimes high and the clouds are higher than 10km, the clouds are low and some tens of meters.

There are many causes of cloud formation, the main reason being the rising moisture . During the upward movement, because the external pressure gas decreases with the height, but its volume increases, so during the process of increasing it needs to consume heat. Thus the air has increased and reduced heat.

We all know the ability to contain water vapor in the air has certain limitations, in certain temperatures, the maximum limit of the air volume unit with the vapor pressure of a corresponding amount of water is called. saturated steam capacity. The pressure of saturated steam decreases with the lowering of temperature. So the temperature in the sky decreases, so the saturated steam pressure doesn't stop.

Cloud formation process.

When the saturation pressure of elevated air falls below the actual water vapor pressure, there will be a steam component combined with dust particles in the space that condenses into droplets (when the temperature is below 0 ^0). C may form small quartz.

The volume of these droplets is very small, they are the components that make up the clouds, its average radius is only a few micrometers, but the density is very large, the speed decreases in tiny air, possibly stored in midair, so it can float in the air and become cloudy.

How can I see the humid air moving up to create clouds? There are several measures:

1. The first is the effect of heat. In the summer days when the sky is clear, because the light and the temperature of the sun are very high, the gas floor near the ground is warming up, the hot and light air is likely to occur when the air moves upwards. The pyramidal clouds and mountains we see on summer days are like that.
2. The second is the effect of 'appearance' . In meteorology, 'style ' is the face of the intersection between hot air and cold air. When the hot air is slightly raised, encountering the obstruction of cold air that is heavy, hot air will actively pass over the tilt of the cold air flow, the intersection face is now called the hot face. . Hot air surpasses the inclined surface of the hot profile, forming thick clouds on a wide range. When the cold air flew up to meet the hot air, it would penetrate the bottom of the hot air and push hot air flying high, the intersection face is now called a 'cold face'. Hot air being forced to fly up on the 'cold surface' can also create thick clouds.
3. The third is the effect of terrain. The humid air of the stratosphere when encountering obstacles of terrain such as plateaus, mountains and hills will be forced to fly up and become clouds or dew on the mountain peak to receive wind.

In addition, due to the turbulent effect of airflow in a perpendicular direction and cold night radiation of the cold air layer, it also causes steam in the air to condense into clouds.

Even though clouds are formed by any method, but because the particles are very small, the speed is slow, only the movement of weak air can hold them, so the clouds can be suspended. in the sky that cannot fall.
