(1) Observing clouds

In the weather calendar we have used Sunny, Cloudy, Overcast

etc. to describe and record observations of cloud cover,

So, how are these different weather conditions divided?

a simple way

Think of the sky as a circle, divide it into four equal parts, fill the circle with the amount of clouds you see, and divide it into sunny, cloudy and cloudy days according to the proportion of clouds in the sky.

Observe the clouds in the sky

Cloud observation should be carried out at an open location or platform where the entire sky and horizon can be seen. Cloud observation should pay attention to its continuous evolution. When observing, if the sunlight is strong, you must wear black or dark-colored glasses.

Observation content

(1) Observe and record the amount of clouds in the sky.

(2) Observe the height of the cloud and the shape of the cloud.

(3) What associations arise when observing clouds?

Cloud classification

Meteorologists classify clouds based on their height and shape.

Meteorologists usually classify clouds into three categories:

Cumulus, stratus 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.

cloud formation

The clouds floating in the sky are actually made up of thousands of small water droplets or ice crystals, and their shapes come in various shapes.

Clouds are not only a scenery in the sky, but also play an important role in human life. If we know the changing patterns of clouds, we can know the changes in the weather.

After class exploration
