Transcript of Clouds
Clouds form when condensation takes place. Clouds are where all three phases of forms of water are commonly in action: gaseous vapor, solid crystals, and liquid droplets.
Why is this important?
Clouds by Class
How does the formation of clouds and movement of air help you to predict the weather?
When it comes to the kinds of weather that you and I worry about most, clouds are where the action is.
Clouds are labeled according to their appearance and according to their altitude.
There are three main types of clouds--stringy, heapy, and layered.
There are only three altitudes--high, middle and low.
There is one more important cloud type--the big, heaped clouds that generate vertically into the sky.
Some of these vertical clouds are so harmless that thy are called fair weather clouds. But others are the monsters that bring the world its most dangerous and violent weather.
in the names of high clouds
means "a curl of hair"
4 Main Types of Clouds
Cirrus clouds are delicate-looking, then, and wispy strands that are silvery and almost transparent against the bright blue sky.
These are commonly carried by the westerlies.
Cirrus clouds tend to form when the wind is strong.
Cirrus clouds are visible during fair weather, but the appearance of cirrus clouds can mean that bad weather is on the way.
if you are in a fog, you are in a stratus cloud that is on the ground
Stratus clouds are often grey and block out much of the Sun.
They grow across the sky in layers.
Stratus clouds often carry precipitation. However, it is usually light rain or drizzle.
Can be associated with days of light, continual rain
Cumulus clouds are tall and puffy.
They can be many different shapes and look a lot like cotton balls.
When sunlight hits these clouds, they are bright white.
Cumulus clouds usually mean fair weather.
Cumulus clouds will most likely appear as a result of a cold front and high pressure system.
Cumulonimbus clouds can't hold all their water droplets.
These drops can become so heavy that they fall as rain, snow, or hail.
These clouds look tall, puffy, and gray.
They are often called storm clouds, and they may bring thunder and lightning.
Most stratus clouds are found lower in the atmosphere, but there are some other types of stratus clouds found at higher altitudes.
We should know about the different types of clouds because clouds can indicate the type if weather that will occur.
