Basics on the topic The Clouds and the Weather

Do you know the different types of clouds?

In this video, you can we learn about four different types of clouds: cirrus, stratus, cumulus and the cumulonimbus clouds, also known as the thunderstorm clouds.

Transcript The Clouds and the Weather

"Today Uma the Weather fairy welcomes you to a very special weather show!" "The clouds and the weather." Clouds come in many different shapes. Some look like animals, others like objects. But, what are clouds made of anyways? Clouds are made up of millions of tiny water droplets and transparent, or see-through air. Kind of like fog, or steam from a teacup! But, why are most clouds white? If a cloud consists of FEW drops of water, the sun can easily shine through it. Then the sunlight reflects the water droplets and it looks like the cloud is white. The darker the cloud, the MORE raindrops are in it. Let's take a closer look at how clouds are formed. Clouds form when there is MORE water in the air than the air can hold. This water comes from the sea, the rivers, the ground, plants, and if it's heated by the sun, the water vapor droplets rise UP. Then, the water vapor cools down the higher it goes, and many water droplets are formed! We call this process 'condensation'. Cloud droplets collect particularly well around small dust particles. The more cloud droplets, the bigger the cloud will be. In order for a cloud to form, it needs: water vapor, cool air and dust particles. But how can we now tell the different cloud TYPES from each other? To do this, we can put the clouds into THREE categories. There are CIRRUS clouds, STRATUS clouds and CUMULUS clouds. Cirrus clouds are very high and consist ONLY of ice crystals. Cirrus clouds are the highest in the sky and look like feathers or wisps of cotton. If you see them in the sky, the weather will probably stay nice for a while. These clouds are expansive and not confined, they often take up a lot of space. The situation is different for CUMULUS clouds. These middle level clouds consist of ice AND water droplets. Their shape has clear edges. They often mean bad weather is coming and look a bit like a herd of sheep. Don't you think so? But there are still STRATUS clouds! These are fair weather clouds. They are scattered across the sky in many large and small clusters. Stratus clouds are low and look kind of like blankets that are layered. In fact, most low clouds look like they are layered. They have greyish-blue bands or rows and predict rain or snow. And then there are the THUNDERSTORM clouds Thunderstorm clouds are called cumulonimbus clouds and they spread over several heights. Remember cumulus clouds? If a cumulus cloud gathers enough water it can turn into a cumulonimbus cloud. These storm clouds look scarily dark and usually mean a thunderstorm is coming. Today we learned about FOUR different types of clouds: cirrus, stratus, cumulus, and the cumulonimbus clouds, also known as the thunderstorm clouds. But is Uma finished with her weather forecast yet?

Ah, Uma is still on the air and seems to be in a storm! Wait, what kind of cloud is that?
