The high humidity and cloud cover of a swamp act as a blanket, holding in the day's heating. The desert lacks humidity and clouds so the heat radiates back into space.
Both a desert and a swamp warm up in the daytime, not cool. They both cool at night with the desert cooling the fastest.
Moist = clouds = heat retention Desert = no clouds = heat loss = cooler
On humid days, such as during the rainy season, swamp (desert) coolers are not very efficient at cooling the air. Air conditioners are not affected by high humidity.
Antarctica is the coldest desert on earth.
No, a desert cools faster than a swamp as it lacks humidity and cloud cover to hold in the heat from the daytime.
A desert cools much faster than a swamp as rock and sand does not retain heat very well, while the water in a swamp is a very good retainer of heat.Clarification:Clouds and high humidity act as a blanket that prevents the heat from a swamp from radiating into space once the sun goes down. The desert usually has no such protection and the heat quickly radiates into space once the sun goes down.
A desert cools much more repidly than a swamp because there is little humidity to help hold the heat.
no sun
It is a function of the "dew point" of the air at any given moment. If relative humidity is high, the dew point will also be high and the swamp cooler air will be relatively warm. If relative humidity is low, the dew point will also be low and the swamp cooler air will be relatively cold. A swamp cooler in Phx AZ will put out air about 30 degrees less than the outside air, and works more efficiently when the humidity outside is very low.
Since the swamp is humid, it cools down a little.
Still hot, but cooler than temperatures in the summertime.
Arizona has a much lower humidity.
