Cloudy nights are warmer than clear nights
Cloudy nights are warmer than clear nights because
- Clouds prevent the escape of heat from the ground
- Clouds absorb sunlight in the day and radiate the same in night
- Clouds make the atmosphere damp and generate heat
- Clouds obstruct the movement of air which creates heat
Answer: Clouds prevent escape of heat from the ground
Cloudy nights are warmer than clear nights because clouds prevent the escape of heat from the ground.
The sun heats the land during the daytime, and at night all the heat goes away into the atmosphere. When there are no clouds in the sky, the majority of this heat is lost to the sky, and hence a gradual cooling effect happens as the night progresses. But when it is cloudy, the clouds trap the heat and radiate back towards the land, resulting in warmer nights.
