What's the difference between cloudy day and cloudy night?

During the day, clouds will weaken the radiation of sunlight on the ground, so cloudy weather is generally dark and the temperature is relatively low during the day; At night, clouds will reflect the surface inverse radiation, and the temperature is higher than that in sunny nights. In addition, the sky is brighter on cloudy nights, mostly orange-red, which is due to the reflection and scattering of ground light by clouds.
