The wide fluctuation in temperatures in most deserts between day and night is due to the lack of a large body of water. Large bodies of water absorb sunlight all day but can hold more heat than the land. When the sun goes down the water is still radiating the heat it absorbed all day making the air around it warmer. The ground radiates heat from the sunlight all day elevating the temperatures in the daytime. When the sun goes down in the desert there is no body of water to keep radiating heat, so the temperature drops more than in a coastal area.
Actually,
A desert has little moisture in the air and few clouds. These two act as blankets to hold in the heat at night. Without a blanket, the heat absorbed by the sand, soil and rocks of the desert is radiated back into space and the temperature drops at night.
What else can I help you with?
How hot can it get in deserts at night?
In deserts, the temperature falls quite a lot, so it's a lot colder in the desert at night than it is in the day. It can fall below freezing.
Why are hot deserts hot during the day but not night?
Because if you have it in the morning aventually the air is going to make it colder
Does it get colder at night in Australia?
Yes. It certainly does get colder at night in Australia. During summer, it takes a lot longer in some areas for the night air to cool down, especially in the far north, but it does get cooler.
What is the climate of the cold deserts in winter?
Climate in the desert varies with location but in some desert areas it can get quite cold, especially at night. Some desert areas also may receive snow, although it generally melts in a short time.
Where are typical hot deserts generally found?
Hot deserts can be found in North Africa, the Middle East, and parts of southwest Asia. But keep in mind that hot deserts can get cold at night.
Is day or night colder?
Generally, night is colder than day. This is because during the day, the sun warms the Earth and its atmosphere, while at night, without sunlight, the Earth loses heat to space, causing temperatures to drop.
What is the temperature of desert in the night?
There are about 2 dozen major desert areas of the world, each with its own climate data. There are hot deserts, there are cold deserts and there are cool deserts. You need to be specific if you want a meaningful answer.
Why do animals in deserts feed at night?
It is generally much cooler at night and most prey animals only emerge in the relative safety of darkness.
How do tropical deserts and temperate deserts differ?
A tropical desert is hot all year long with exception to night time (all deserts get cold when it is dark). Temperate deserts have a winter season in which the desert gets colder during daylight hours, unlike tropical deserts.
Why are deserts so hot at night?
they aren't. Deserts are usually cold at night.
Why are the deserts very cool at night times?
Generally, deserts have low humidity and little cloud cover. These two factors act as a blanket holding in daytime heating. Without that 'blanket' the heat radiates back into space at night. Deserts, therefore, cool off quite quickly and noticibly once the sun goes down.
Why do deserts have a large temperature change everyday?
Deserts generally lack cloud cover and higher humidity that act as insulation and buffer the temperature changes during the day. Therefore, deserts heat up quickly during the day and cool down quickly at night.
