The desert climate or arid climate (in the Köppen climate classification BWh and BWk) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive.
Saudi Arabia's Köppen climate classification map.. The climate of Saudi Arabia is marked by high temperatures during the day and low temperatures at night. The country follows the pattern of the desert climate, with the exception of the southwest, which features a subtropical highland climate and a semi-desert climate.
The climate of Africa is a range of climates such as the equatorial climate, the tropical wet and dry climate, the tropical monsoon climate, the semi-arid climate (semi-desert and steppe), the desert climate (hyper-arid and arid), the humid subtropical climate, and the subtropical highland climate. Temperate climates are rare across the ...
The climate is generally extremely dry all over the country except on the northern Mediterranean coast which receives rainfall in winter. In addition to rarity of rain, extreme heat during summer months is also a general climate feature of Egypt although daytime temperatures are more moderated along the northern coast .
Phoenix has a hot desert climate (Köppen: BWh), [1] [2] typical of the Sonoran Desert, and is the largest city in America in this climatic zone. [3] Phoenix has long, extremely hot summers and short, mild winters. The city is within one of the world's sunniest regions, with its sunshine duration comparable to the Sahara region.
High desert regions typically have the greatest diurnal-temperature variations, while low-lying humid areas near the shores (tropical, oceanic, and arctic) typically have the least. Large cities (urban heat islands) also tend to have a lowed diurnal temperature variation than surrounding areas.
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...
In his book Libyan Sands, Ralph Bagnold went as far as to suggest that the Libyan Desert was a separate geographical entity from the Sahara, cut off by the mountains and plateaus of the Ennedi and Tibesti in northern Chad, and the Akakus and Tassili n'Ajjer along the Algerian border in the west. Since that time the meaning has come to revert to ...
