How Do Clouds Form
If your question is how do clouds form, we have your answer! Clouds are formed as part of the water cycle of our planet. When the water vapor in the atmosphere is cooled and condensed as part of that water cycle, clouds are formed. Sometimes they look like puffy marshmallows, but they are actually made up from billions of tiny water droplets and/or ice crystals that float in the sky above. They can appear in a wide variety of shapes, sizes and colors, as all of us have seen I would imagine. Their shapes and sizes vary depending on how and where they were formed.
Now that we know how do clouds form, and that clouds are formed when the rising air and moisture cools and condenses to form water droplets. But why does air rise? Most of us are, or should be aware that hot air rises typically. So lets explore the primary reasons why the air rises.
Air rises for three primary reasons:
- Sun – The sun heats the ground and the air which in turn makes it lighter, thus allowing it to rise.
- Terrain – Air can rise as it gets forced upwards due to the terrain changes in it’s path. This can occur when the wind is blowing air over the mountains, or rising up from the sea over cliffs and onto the land.
- Weather Fronts: Air may also rise at what is called a weather front. At a cold front, the colder air is forced under the warmer air, thus forcing the warmer air upwards. In a warm front, the warm moist air is forced over the colder air. This usually leads to severe storms as most of us have witnessed over the last several years.
Types of Clouds
Cirrus Clouds: These are high-level, wispy or feathery clouds formed very high in the atmosphere at altitudes ranging between 5 and 14 kilometers where it istypically very cold. Since the air is very cold that high in the atmosphere, the Cirrus clouds are made up of tiny ice crystals and not water droplets. Cirrus clouds will typically form in warm air which is slowly lifted over a large area by an approaching cold front, and they typically are a sign of a coming storm or bad weather. Cirrus clouds can also be referred to as Mare’s tails, due to the fact that the high winds at the altitudes where they form blow them into the wispy curls associated with them, similar to that of a horse tail, hence Mare’s tails!
Cumulus Clouds: These are very fluffy, and look like large heaps of cotton or marshmallows. These are formed when the sun warms pockets of moist air whichcauses them to rise quickly. The the pockets of air get higher, the air pocket billows out and forms the familiar shapes associated with these clouds as the moist air cools and condenses into water droplets. These are typical in good weather, and can be seen for miles, as they are typically found at roughly 500 meters high. When we were kids, we would watch these clouds and see what objects they resembled. Sometimes they can resemble animals, sometimes they look like people, and sometimes they look like cars or boats or trains, or other neat objects, even hearts! These clouds are fun to watch and let your imagination go and see what you think they look like!
Stratus Clouds: Stratus clouds are low lying blankets of clouds, and are often dark and gloomy looking, and when they are low enough, they become what we call fog.These clouds look shapeless and extend in all directions overhead. They are not very thick, typically only 1 kilometer, but can stretch out to as wide as 1,000 kilometers. These form when a layer of warm, moist air rises slowly over a mass of colder air, and are often found to create rain and drizzle.
So we have told you how do clouds form, and we have mentioned the three major types of clouds, but these three primary cloud types can combine with each other to form other types of clouds like the cumulonimbus, cirrostratus, and stratocumulus. There are 10 different varieties of clouds altogether.
We hope that we have answered your question how do clouds form, and enjoy them as we do. Peace my friends and happy cloud watching!
