What are cold deserts where are they located and why are the not hot?
Temperate or cold deserts occur in temperate regions at higher latitudes—and therefore colder temperatures—than those at which hot deserts are found. These dry environments are caused by either remoteness from the coast, which results in low atmospheric humidity from a lack of onshore winds, or the presence…
Are there cold deserts?
Cold deserts have hot summers but extremely cold winters. These deserts are found in high, flat areas, called plateaus, or mountainous areas in temperate regions of the world. Temperate regions lie between the polar regions and the tropics. The Gobi Desert in Central Asia is one of the coldest deserts in the world.
Where are cold deserts usually found?
Cold deserts are found in the Antarctic, Greenland, Iran, Turkestan, Northern and Western China. They are also known as polar deserts. These deserts are generally found in certain mountainous areas. Some famous cold deserts are: – Atacama, Gobi, Great Basin, Namib, Iranian, Takla Makan, and Turkestan.
Where is the coldest desert on earth?
The largest desert on Earth is Antarctica, which covers 14.2 million square kilometers (5.5 million square miles). It is also the coldest desert on Earth, even colder than the planet’s other polar desert, the Arctic. Composed of mostly ice flats, Antarctica has reached temperatures as low as -89°C (-128.2°F).
What is cold desert?
The Cold Desert, also known as the Katpana Desert or Biama Nakpo, is a high-altitude desert located near Skardu, Gilgit−Baltistan, Pakistan. The desert contains large sand dunes that are sometimes covered in snow during winter.
What is cold desert answer?
Cold deserts are places which have hot summers but the winters are extremely cold. Generally, such areas occur in high, flat areas, called plateaus, or mountainous areas in temperate regions of the world. Antarctica is the largest cold desert of the earth.
How cold is a cold desert?
Cold deserts have a mean annual temperature of less than 18 °C and no more than 200mm of precipitation annually. Cold desert climates usually feature hot (or warm in a few instances), dry summers, though summers are not typically as hot as hot desert climates.
How are cold deserts formed?
It is formed due to atmospheric conditions that prevent rain. Cold deserts are formed in temperate regions, at higher altitudes and are located at the centre of the continent. Because of the low temperatures, pressure, moisture, distance from sea, and poor vegetation; precipitation is very low in these regions.
How is a cold desert formed?
Why is there no rainfall in the desert?
Humidity—water vapor in the air—is near zero in most deserts. Light rains often evaporate in the dry air, never reaching the ground. Rainstorms sometimes come as violent cloudbursts. A cloudburst may bring as much as 25 centimeters (10 inches) of rain in a single hour—the only rain the desert gets all year.
Why do deserts have such high temperatures?
The reasons for the high temperatures are obvious—a clear, cloudless sky, intense insolation, dry air and a rapid rate of evaporation. Coastal deserts by virtue of their maritime influence and the cooling effect of the cold currents have much lower temperatures, e.g. Arica has a mean annual temperature of 66°F.,
What is the highest temperature ever recorded in the desert?
The deserts are some of the hottest spots on earth and have high temperatures throughout the year. There is no cold season in the hot deserts and the average summer temperature is around 86°F. The highest shade temperature recorded is 136°F. On the 13 September 1922 at Al Azizia, 25 miles south of Tripoli, Libya, in the Sahara.
Why are interior deserts found in the heart of continents?
Interior desert s, which are found in the heart of continents, exist because no moisture-laden winds reach them. By the time air masses from coastal areas reach the interior, they have lost all their moisture. Interior deserts are sometimes called inland deserts.
What is the distribution of deserts?
Distribution of Deserts: Deserts are regions of scanty rainfall which may be hot like the hot deserts of the Saharan type; or temperate as are the mid-latitude deserts like the Gobi. The aridity of the hot deserts is mainly due to the effects of off-shore Trade Winds, hence they are also called Trade Wind Deserts.
