Desert climate (in the Köppen climate classification BWh and BWk, sometimes also BWn), also known as an arid climate, is a climate that does not meet the criteria to be classified as a polar climate, and in which precipitation is too low to sustain any vegetation at all, or at most a very scanty shrub.
An area that features this climate usually experiences less than 250 mm (10 inches) per year of precipitation and in some years may experience no precipitation at all. In some instances, an area may experience more than 250 mm of precipitation annually, but is considered a desert climate because the region loses more water via evapotranspiration than falls as precipitation (Tucson, Arizona and Alice Springs, Northern Territory are examples of this).
There are usually 2 or three variations of a desert climate: a hot desert climate (BWh), a cold desert climate (BWk) and, sometimes, a mild desert climate (BWh/BWn). Furthermore, to delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: either a mean annual temperature of 18 °C, or a mean temperature of 0 °C or -3 °C in the coldest month, so that a location with a "BW" type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid" (BWh), and a location with the appropriate temperature below the given isotherm is classified as "cold arid" (BWk).
Deserts occupy more area of the surface of our planet than any other type of landscape. They occur in all climatic zones including the hottest and coldest locations on Earth. This program examines deserts around the world, explaining why they exist and the different climate drivers at work in their formation and physical characteristics. It also covers human life in deserts and the various ways in which people adapt to living in a dry environment, and their impact on fragile desert ecosystems. It features a range of imagery of different deserts around the world, and uses graphics to clearly explain the natural processes at work.

Brief information about hot desert climate
"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And terrifyingly, it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes -- and his work so far shows -- that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

How The Sahara Desert Was Made Documentary No greater mysteries than the Sahara desert, the hottest place in the planet, a deadly waste land time had got or so scientist believed until they revealed the enigmatic fuze, the fossiled remains of sea creatures, fresh water shells buried in the sand, ancient settlement containing human bones. These discoveries provided the clear evidence that this stark landscape can hide turbulent past one that can alter the course of human history and write a dramatic chapter in the story of How the earth was made.
An interesting documentary about the world famous US Air Force bone yard for surplus or out dated aircraft. Davis–Monthan Air Force Base (DM AFB) (IATA: DMA, ICAO: KDMA, FAA LID: DMA) is a United States Air Force base located within the city limits approximately 5 miles (8.0 km) south-southeast of downtown Tucson, Arizona. It was established in 1925 as Davis-Monthan Landing Field. The host unit headquartered at Davis–Monthan is the 355th Fighter Wing assigned to Twelfth Air Force, part of Air Combat Command (ACC). The base is best known as the location of the Air Force Materiel Command's 309th Aerospace Maintenance and Regeneration Group (AMARG), the aircraft boneyard for all excess military and government aircraft. Overview[edit] Davis–Monthan Air Force Base is a key ACC installation. Th...
"Bahr Belá Má", "Waterless Sea", as the Sahara is called by the Bedouins. But deep beneath the dune fields and stone deserts expands an immeasurable reservoir of water resources. Using enormous technical resources, the Libyans have begun to extract fossil reserves of groundwater. Following oil, water is now arousing a new wave of euphoria. In the present desert climate, reserves are only being partally replaced and what has collected over a period of millions of years may be used up in only a few decades.
