Why does a cloudless desert sky at night mean that the temperature will get much colder?

During the daytime, the Sun will heat up the ground and the atmosphere with its electromagnetic radiation: usually it's the infrared light. During the nighttime, the Earth will send back the accumulated heat during the day to the space, by emitting infrared radiation, which refreshed the ground and the atmosphere.
A cloudless skies and a dry air will accentuate this effect because the cloud cover and the water vapor within the atmosphere prevent brutal heating or brutal cooling: indeed, a high cloud cover will block and prevent any radiation emitted by the Sun or by the Earth to reach the ground or the atmosphere respectively. In addition, dry air can be heated up or cooled off a lot faster than moist air because heating or cooling water vapor takes more time. That's why the diurnal temperature ranges can be high in hot deserts with many cloudless skies and the dryness of the air.

What is the climate in the desert at night?
The very dry air of the desert holds little moisture and thus holds little heat so as soon as the sun sets, the desert cools considerably. Clear, cloudless skies also help to quickly release heat at night. Mos deserts have very low temperatures at night.
What the temperature in the desert in the night time?
The desert is cold at night. This is because there are no clouds or trees to hold in the heat.

What is the variance of temperature between day and night in the desert?
That would depend upon which desert and your specific location in that desert.
Can a desert at night get below 30 degrees?
Cold winter deserts can drop well below 0 degrees F in winter. The Gobi has been known to drop to -40 degrees or even colder. The Antarctic Desert has had a temperature measured at -135.8 degrees F.
On a cloudless day how many stars can been seen?
Only one ... the sun. It's quite a different matter on a cloudless night.
How is the temperature in the Gibson Desert?

What is the temperature degrees Fahrenheit at night in the desert?
