Hot deserts climate
Hot desert have a mean annual temperature of at least 18 °C and no more than mm of precipitation annually. These climates usually feature hot, sometimes exceptionally hot, periods of the year. Temperature of Hot Desert Climate: On the basis of annual distribution of temperature two distinct seasons are recognized e.g. summer season and winter season. Average temperature during summer season ranges between 30°C and 35°C but maximum temperature exceeds 40°C during mid-day.
Robotshop how to build a robot or arid climate is experienced in arid regions and it is characterized by very low precipitation, ranging between 25 mm and mm annually. In some deserts such as Arica in Chile, the average annual rainfall is about 1 mm.
In some years, some deserts may experience no rainfall at all. Some areas that experience precipitation exceeding mm annually but lose more water through evapotranspiration also fall under the desert climate. There dssert two main variations of this climate, the hot desert climate and the cold desert climate.
The third variation, which is not as common as the first two, is the mild desert climate. Isotherms are lf to determine the dwsert types of desert climates. The most common and accurate one is an average annual temperature of 18 0 C. If the mean annual temperature of an arid region falls above the isotherm, the region is classified as a hot desert with a hot desert climate.
Cold whaat are areas whose mean climats temperatures fall below the isotherm. Other isotherms used to differentiate desert climates are 0 0 C or an average temperature of -3 0 C during the coldest month. Areas that experience hot climtae climates are found within the 30 0 N and 30 0 S latitudes.
This belt is known as the subtropical ridge, and it is an area of high atmospheric pressure. Generally, the climate in these areas is hot, dry, and sunny throughout the year. In summer, the maximum temperature may soar to 40 0 C and the hottest regions sometimes what temperature should a newborn baby bath be temperatures exceeding 45 0 C.
The annual average temperature in hot deserts is usually very high, at times surpassing 30 0 C. Nights are generally colder than days and during the coldest months of the year, night-time temperatures may drop thd freezing point. The cold nights are due to excessive loss of radiation beneath the clear desert skies. Cold desert climates are mainly found in temperate zones, usually on the leeward side of high mountains. The peaks block moisture-bearing winds from advancing into these regions, hence restricting precipitation.
They occur at higher altitudes compared to hot desert climates. Summers in cold desert climates are hot and dry while winters are cold, dry, and they also lack snow.
Deserts that experience this climate are drier than those that lie within the hot desert climate. The Tabernas Desert of Spain experiences a cold desert climate.

Hot deserts can be really hot during the day, but at night the temperature can fall to below freezing point (32?F or 0?C). This is because there are no clouds in the desert sky to keep the heat in at night. The Sahara in Africa is the largest hot desert in the world. The hottest temperature ever recorded in the Sahara was ?F (57?C) in Jun 13, · The weather in a hot desert climate is, needless to say, very hot and dry. During summer months, average temperatures of above 30° Celsius are common, with many days exceeding 40° Celsius. Winter months are colder, but temperatures remain high. A hot desert climate is also characterized by contrasting weather.
The typically bald, rocky, or sandy surfaces in desert climates hold little moisture and evaporate the little rainfall they receive. Covering Although no part of Earth is known for certain to be absolutely rainless, in the Atacama Desert in northern Chile, the average annual rainfall over a period of 17 years was only 5 millimetres 0.
Some locations in the Sahara Desert such as Kufra , Libya record only 0. The official weather station in Death Valley , United States reports 60 mm 2. To determine whether a location has an arid climate, the precipitation threshold is determined. If the area's annual precipitation is less than half the threshold, it is classified as a BW desert climate. There are two variations of a desert climate: a hot desert climate BWh , and a cold desert climate BWk.
In these locations, stable descending air and high pressure aloft create hot, arid conditions with intense sunshine.
Hot desert climates are found across vast areas of North Africa , the Middle East , northwestern parts of the Indian Subcontinent , interior Australia, and smaller areas of the Southwestern United States , and Chile.
At the time of high sun summer , scorching, desiccating heat prevails. This includes the record of Some desert locations consistently experience very high temperatures all year long, even during wintertime. This last feature is seen in sections of Africa and Arabia. During colder periods of the year, night-time temperatures can drop to freezing or below due to the exceptional radiation loss under the clear skies. However, very rarely do temperatures drop far below freezing.
Hot deserts are lands of extremes: most of them are among the hottest, the driest and the sunniest places on Earth because of nearly constant high pressure; the nearly permanent removal of low pressure systems, dynamic fronts and atmospheric disturbances; sinking air motion; dry atmosphere near the surface and aloft; the exacerbated exposure to the sun where solar angles are always high.
Cold desert climates BWk usually feature hot or warm in a few instances , dry summers, though summers are not typically as hot as hot desert climates. Unlike hot desert climates, cold desert climates tend to feature cold, dry winters. Snow tends to be rare in regions with this climate. The Gobi Desert in Mongolia is a classic example for cold deserts. Though hot in the summer, it shares the very cold winters of the rest of Central Asia. Cold desert climates are typically found at higher altitudes than hot desert climates and are usually drier than hot desert climates.
Cold desert climates are typically located in temperate zones, usually in the rain shadow of high mountains, which restrict precipitation from the westerly winds.
An example of this is the Patagonian Desert in Argentina bounded by the Andes to its west. In the case of Central Asia, mountains restrict precipitation from the monsoon. The Ladakh region, and the city of Leh in the Great Himalayas in India, also has a cold desert climate. The Hautes Plaines is another major example of cold desert climates, located in the northeastern section of Morocco and in Algeria.
