When the air is clear, heat radiates from the ground into space, with a temperature difference of about 290 degrees C. ("Space" has a temperature of about -270 degrees C, or 4 degrees Kelvin.) When there are clouds, the ground radiates heat to the clouds, with a temperature difference of a few dozen degrees C.
What else can I help you with?
Are cloudy nights usually warmer or colder than clear nights?
Cloudy nights are usually warmer than clear nights because clouds act as a blanket, trapping heat emitted from the Earth's surface. This phenomenon prevents heat from escaping into the atmosphere, resulting in higher temperatures during the night.
Why is it that cloudy nights are usually warmer than clear ones?
Clouds act as a blanket, trapping heat emitted from the Earth's surface. This greenhouse effect prevents heat from escaping into the atmosphere, resulting in warmer temperatures on cloudy nights compared to clear nights when heat is able to escape freely.
Are cloudy nights lightly to be warmer than clear nights?
Generally, yes. Radiative cooling when there are no clouds makes things cooler - all things being equal , of course...
Why does cloudy nights have higher temperature than clear nights?
Cloud cover acts as a blanket, trapping heat from the Earth's surface and preventing it from escaping into the atmosphere. This leads to warmer temperatures on cloudy nights compared to clear nights, where heat can escape more easily into space.
Why are cloudy night warmer than clear night?
because of the greenhouse effect
Clear nights are colder than cloudy nights because?
clear nights allow heat to escape into the atmosphere more easily, leading to cooler temperatures. Clouds act as a blanket, trapping heat and preventing it from escaping, resulting in warmer temperatures on cloudy nights.
Why do cloudy nights have high temperatures than clear nights?
Cloudy nights have high temperatures than clear nights because clouds trap heat radiated from the Earth's surface, creating a greenhouse effect that keeps the air warmer. On clear nights, without clouds to trap the heat, it escapes back into space, causing temperatures to drop.
Why cloudy days and nights are warmer than the cloudless one?
Cloudy days and nights are warmer because clouds act as a blanket, trapping heat that is radiated from the Earth's surface, preventing it from escaping into space. This trapped heat helps to keep temperatures warmer compared to clear nights when heat can escape more easily.
Why is it clear night is more cooler than a cloudy night?
During a clear night, heat from the surface of the Earth radiates out into space since there are no clouds to trap it. Clouds act as a blanket, trapping heat near the surface and preventing it from escaping, which leads to warmer temperatures on cloudy nights compared to clear nights.
Why cloudy nights are warer than the clear nights?
Why are you warmer when you have a blanket on your bed than when you have nothing on your bed? Heat radiates into space. Clouds hold the radiation close to the earth and prevent it from escaping into space. Clouds work the same way a blanket works.
Cloudy nights can be warmer than clear nights because clouds trap heat -?
Yes, that's correct. Clouds act as a blanket, reflecting and trapping heat back towards the Earth's surface. This phenomenon prevents heat from escaping into the atmosphere, leading to warmer temperatures at night.
Why it is usually colder in clear nights than on nights witch cloudy skies?
Clear nights allow heat to escape into the atmosphere more easily, leading to cooler temperatures. Clouds act as a barrier, trapping heat and preventing it from escaping, resulting in warmer temperatures.
