Clouds are water droplets remaining in the air, formed by the condensation or re-sublimation of water vapor.
There are 10 main types of clouds.
How do clouds stay in the air?
Clouds stay in the air thanks to the phenomenon of microturbulation, which prevents gravitational subsidence. Clouds are very heavy but consist of individual droplets which maintains air resistance.
How much do the clouds weigh?
There are several grams of water in 1 cubic meter of cloud. It seems little, but let’s remember about their enormous size. There can be hundreds of thousands of tons of water in the clouds that cover the visible sky. Storm clouds over 10 km in diameter can have a volume of over 900 billion cubic meters. Its weight may exceed 4 billion tons.
When does it begin to rain from the cloud?
It is when small parts of the condensed vapor merge into larger droplets which fall to the ground under gravity.
Why do white clouds turn black?
The darker the cloud, the more water it has accumulated to trap the sun’s rays.
How can clouds be divided?
One of the methods of cloud division is:
- height of occurrence (high, medium, low clouds),
- shape (pinnate, layered, cumulus clouds),
- (clouds with a horizontal extent, extended vertically),
- way of creation (wave clouds, convection clouds, front clouds)
What are the types of clouds?
There are 10 types of clouds:
- Altocumulus (medium cumulus),
- Altostratus (medium layer),
- Cirrus (feathery),
- Cirrocumulus (pinnate),
- Cirrostratus (pinnate),
- Cumulus (cumulus),
- Cumulonimbus (cumulus and rain),
- Nimbostratus (layered rain),
- Stratus (layered),
- Stratocumulus (cumulus-layered).
What is cloud extraction?
It is a short-lived rain of very high intensity. Several cm of water may drop in a few minutes.
When does hail occur in the cloud?
Hail is raindrops formed at an altitude of over 10 km where the temperature drops below -50 ° C.
Why are the clouds white?
As light passes through the cloud, it interacts with water droplets, evenly scattering all the colors of the light spectrum. This keeps the sunlight white, forming white clouds.
Cloud interesting facts
1. The largest clouds can be over 18 km thick.
2. By observing the behavior of the clouds, you can accurately predict the weather for just the next three hours.
3. Cumulonimbus is the most dangerous type of cloud (storm cloud). Its diameter often exceeds 10 km and reaches 15 km in height. When you see it in the sky, you should look for a safe haven.
4. Scientists are constantly trying to understand what causes the drops to start to merge at any given moment. At the moment, it is not possible to accurately predict when it will start raining from the rain cloud.
5. At an altitude of 15-25 km in the polar regions there are stratospheric clouds.
6. There are different kinds of clouds on every planet in the solar system.
7. On Venus, clouds are made of sulfuric acid droplets. They are so dense that they hardly let any solar radiation pass through them.
8. There are clouds made of ammonia on Saturn and Jupiter.
9. There are clouds made of methane on Neptune and Uranus.
10. Clouds can travel at speeds over 150 km / h.
