What's the cloudy weather forecast?

Cloudy means: the sky becomes cloudy at level 2-8.

More clouds just means that the number of clouds you see accounts for a large area of the sky.

The state of the sky is determined by the amount of clouds in the sky and the intensity of sunlight.

There are four situations: sunny, partly cloudy, cloudy and cloudy.

Sunny days: the sky is cloudless, or the medium and low clouds are less than 1%, and the high clouds are below 40%.

Partly cloudy: there are 1% ~ 30% medium-low clouds or 40% ~ 50% high clouds in the sky.

Cloudy: There are 40% ~ 70% medium-low clouds or 60% ~ 10% high clouds in the sky.

Cloudy day: It is dark, covered with clouds, or slightly cloudy, but it still feels dark.
