According to the amount of clouds, the weather can be divided into

According to the amount of clouds, the weather can be divided into sunny days, cloudy days and cloudy days. Clouds in the sky will change, and different clouds indicate different weather.

Cloud cover refers to the area in the sky occupied by clouds. Sunny, partly cloudy, cloudy and cloudy weather forecast broadcasts are divided according to cloud cover. There are no clouds in Wan Li, or there are scattered clouds, but the amount of clouds is less than 20%, which is called sunny;

More than 80% of low clouds are called cloudy days. When the middle and low cloud amount is 1 ~ 3 and the high cloud amount is 4 ~ 5, it is called partial cloudy. It is cloudy when the middle and low cloud cover is 4 ~ 7 and the high cloud cover is 6 ~ 10.

How to divide different weather conditions according to the cloud amount: treat the sky as a circle, divide it into four parts on average, fill in the cloud amount you see in this circle, and distinguish it according to the cloud amount in the sky.

Extended data

Seasonal distribution characteristics:

The change of the total amount in different seasons is not obvious in the middle and high latitudes, but mainly concentrated in the low latitudes near the equator. In autumn and winter in the northern hemisphere, the total cloud amount is less than that in spring and summer. On the contrary, in the southern hemisphere, there are more clouds in autumn and winter than in spring and summer.

It can be seen that there is an obvious low cloud cover area near North Africa, Arabian Peninsula and West Asia, with obvious seasonal north-south swing, which may be related to the north-south swing of the direct latitude of the sun on the earth.
