What's the difference between cloudy and cloudy days? Is there a sun on a cloudy day?

The difference between cloudy days and cloudy days is as follows:

1, the total cloud cover in the sky is different.

There are many cloudy days, with moderate and low clouds accounting for 4/ 10-7/ 10 or high clouds accounting for 6/ 10- 10, and the total low clouds on cloudy days are 8/ 10 and above.

2. The intensity of sunlight is different.

It's cloudy and sunny, but you can still see sunny days through the cracks in the clouds. There is little or no sunlight through the clouds on cloudy days.

3. Rainfall forms in different ways.

Cloudy weather There are clouds in the sky, but it can't form rain. The sky is full of cumulus clouds. Cloudy days can form precipitation, and there are cumulonimbus clouds or stratocumulus clouds in the sky.

Extended data

There are five weather conditions:

1, sunny: it means that the cloud cover in the sky is less than 30% (that is, 30%).

2. Cloudy: It refers to the sky condition when there are 4-70% medium-low clouds or 6- 10% high clouds in the sky.

3. Partly cloudy: it is the sky condition when there are 1-30% medium-low clouds or 4-50% high clouds in the sky.

4. Cloudy day: It is a weather phenomenon that the sky is dark and the clouds are densely covered, or the sky still feels dark despite the clouds (accounting for more than 80% of the total clouds), and occasionally a faint sunshine can be seen from the clouds.

5. Fog refers to a visible aggregate of a large number of tiny water droplets (or ice crystals) suspended in the atmosphere near the ground.
