"Cloud Observation" Weather PPT

Description

"Cloud Observation" Weather PPT

Part One: Observing Clouds

In the weather calendar we have used the terms sunny, cloudy, overcast, etc. to describe and record observations of cloud cover. So, how are these different weather conditions divided?

Think of the sky as a circle, divide it into 4 equal parts, fill the circle with the amount of clouds you see, and classify them according to how much clouds occupy the sky.

Try to observe clouds using the methods you have learned, and describe and record them.

Cloud Observation PPT, Part 2: Classifying Clouds

When meteorologists describe clouds, they usually divide them into three categories: cumulus clouds, stratus clouds and cirrus clouds.

Flat, layered clouds that form close to the Earth's surface are stratus clouds. Stratus clouds are usually gray. Stratus clouds sometimes cover most or even the entire sky. If stratus clouds become thicker, drizzle, heavy rain, or snow will occur, so they are also called nimbostratus clouds.

Clouds that are higher than stratus clouds and look like cotton piles are called cumulus clouds. Cumulus clouds are usually associated with sunny weather, but they can develop into cumulonimbus clouds and form thunderstorms.

Thin plumes are cirrus clouds. Cirrus clouds can only form at high altitudes where temperatures are very low, so cirrus clouds are composed of tiny ice crystals.

Go outside the classroom and look at the clouds in the sky to see what type of cloud they are.

During the cloud observation process, try to find these three different types of clouds and record them in the corresponding weather calendar.
