UPSC IAS – 2019
On a cloudy night, clouds act as a thermal blanket. They efficiently absorb the outgoing long-wave radiation emitted by the Earth’s surface. The absorbed energy warms the clouds, and they re-emit radiation in all directions, including back down towards the Earth’s surface. This downward radiation reduces the net loss of heat from the surface.
