What is a cloud?
Clouds refer to the sum of water particles floating in the atmosphere of the Earth or any other planet. Normally water is not stationary anywhere in the world, it is circulating through different channels and the conditions are changing. We normally see water in solid, liquid, gaseous three states. Clouds are a form of gaseous state. The largest and most sustainable source of water is the sea, as well as rivers and canals. By evaporating from the heat of the sun, water from these sources becomes lighter and evaporates, and this steam cools and condenses to form floating clouds.
Rain from the clouds
At first, as the water vapor rises from the surface, it cools and condenses. It usually starts condensing from 75,000 feet above the ground. This condensed cloud is a lot like dense fog. When these fog reaches frozen areas due to strong winds, they become colder and turn into water particles. With the warm air from the bottom, the dust particles actually accumulate in the center of this dust. At one stage, when the water particles are larger than 5 cm, it falls to the ground due to gravity. The shape of these raindrops can often be small or large. Temperature plays a special role in rain. Just as the cool air above cools the steam and turns it into a cloud, the warm air below contributes to the precipitation of rain from the clouds.
Hail
Many times the water particles become extra cold and turn into tiny ice caps. As these ice particles reach the surface through the frozen region, the volume of ice particles increases due to the surrounding frozen condensed fog. The average diameter of a rock can be 5 to 150 millimeters. Clouds are usually responsible for hailstorms (ঈঁহরড়হরসং প প প '').
In stormy and critical weather, when strong winds blow upwards, rocks are formed. Warm air rises to the top, and cold air descends to the bottom. When a sufficient amount of frozen water source is created there, ice accumulates in the clouds ণে a combination of cool water granules and cool air.
The upward wind reaches a point where the temperature drops below zero and the water begins to freeze. At one stage, the ice created in the upward wind escapes from the wind and falls downwards. After ascending to the top of this upward wind, the process of descending due to the formation of ice particles continues. The coating on the ice particles accumulates and forms into ice cubes. This upward wind has to have a very good speed, in some cases this speed can be up to 60 miles / hour.
As the rock begins to fall from the sky, it melts slightly in a falling state, and melts at a temperature that causes it to rise again with the upward wind. So, from this it is understood that very large sized rocks are actually the crop of many times recycled.
These rocks shelter rainwater particles or clouds, and when they become increasingly heavy and the upward wind can no longer carry such a heavy load, the rocks begin to fall to the ground with the rain. Which we see as hail.
Clouds are divided into two classes in terms of behavior and characteristics: stratified and mobile. Clouds are basically classified by the height of their feet, not by the height of their peaks. This method was proposed in 1802 by Luke to the Assyrian Society.
The classification of clouds is behaviorally stratified and convex, but in terms of height, it is divided into high, medium and low.
These clouds are usually 30,000 to 40,000 feet. Due to this huge height, the light of the sun cannot penetrate the clouds and come to the earth, making the clouds look black.
Different types of clouds
1. Cirrus clouds: All these clouds look like ice crystal fins. They are formed at many heights above the clouds. Some of them are formed at a height of about ten miles from the surface of the earth.
2. Horizontal clouds (Stratus clouds): This type of cloud is usually formed only a few hundred feet above the ground. They are like light-thin fog. This type of cloud is seen when the wind is still in the morning or evening.
3. Cumulus clouds: These are beautiful accumulated clouds. This type of cloud is called shadow cloud. They can be seen in the sky in summer.
It also stays just a mile above the ground and casts a fast-moving shadow on the ground. When the sun is most warm in the mid-afternoon, they increase in size and number, and their tops rise to a height of a few miles. In the evening, they merge into horizontal clouds and disappear.
4. Nimbus clouds: These are dark gray rain clouds. Their structure is formless. The lower half of the rain cloud is heavier than water droplets which sometimes turn into raindrops and fall down. The different types of clouds mentioned above can also be seen in connected form.
5. Auto-cumulus clouds are round, large, white or gray. These are densely embedded forms of six small clouds. They can be seen at an altitude of eight to twenty thousand feet.
6. High horizontal clouds (Alto-stratus clouds) look like thick, gray bluish leaves at an altitude of six and a half to twenty thousand feet above the ground.
7.A dense horizontal cloud (Cirro-stratus) is a thin white sheet-like cloud composed of ice crystals at an altitude of 20,000 feet.
8. The Cirro-cumulus is a piece of cloud formed inside a dense cloud that looks like a wave of sand on the coast. This cloud is formed at an altitude of twenty thousand feet.
9. Cumulonimbus clouds This cloud is called lightning head. They look a lot like cauliflower. Such clouds can be seen up to the top of the atmosphere.
10. Strato-cumulus clouds are those point-point clouds that extend from near the Earth's surface to an altitude of six and a half thousand feet.
