There is no cloud cover to reflect heat back to the surface. Heat escapes into space.
Warmer, they have a greenhouse effect and trap heat.
Clouds act as a kind of blanket for our atmosphere, trapping in heat. A clear night does not retain as much heat, so tend to be colder.
Clear nights often mean high pressure sytems which often means cold air. Cloudy nights often mean low pressure systems which often mean warm air.
Because the clouds cover up the cold air that tries to get into Earth.

because of the greenhouse effect
The clouds prevent air from escaping so the cold air can't get in because of the clouds are blocking it t works like a blanket
Clouds prevent heat from being radiated out into space, it is reflected back to earth, much like a blanket keeps you warm.
During a clear night, as heat absorbed by the earth during the day seeps out, the atmosphere allows the heat to pass through. During a cloudy night, however, the clouds catch and retain the heat in the atmosphere.Clouds trap heat being reflected from the earthThe heat radiation lost from the earth gets reflected by the clouds back to the earth, warming it. Whereas on a clear night it just escapes into space.
Generally, yes. Radiative cooling when there are no clouds makes things cooler - all things being equal , of course...
Cloudy to clear
WHERE??? CLEAR AND CLOUDY WHERE??? CLEAR AND CLOUDY
