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.
May 13, 2019 · An arid climate is known for being hot and dry. About a third of the Earth is covered by arid climate most of which lie 30 degrees north and south of the Equator. Despite the harsh conditions animals and plants have developed adaptive methods to survive the environment.
Aridity is the condition of a region that severely lacks available water, to the extent of hindering or preventing the growth and development of plant and animal life. Regions with arid climates tend to lack vegetation and are called xeric or desertic.
Nearly 33% of the Earth's land is covered in Arid climate. The word arid means dry. The two colors on the map represent warm and cold Arid climates. If land has an Arid climate it is usually a desert. Most deserts are found along the 30 degree latitude line (north and south of the equator).
Arid Climates. An arid climate is one that receives less than 10 inches (25.4 centimeters) of rainfall in an entire year. Deserts are areas that are arid. Although the most familiar image of a desert involves hot sand, the Arctic North and Antarctica are also deserts, as they also receive little moisture, usually in the form of snow. In ...
Mar 13, 2018 · The defining characteristic of an arid climate is a lack of moisture. The soil is dry, the air is dry, and yearly precipitation is very low. A variety of factors combine to steer storms and moisture away from arid regions.
The hottest spots in the world are in arid climates. The temperature in the arid Death Valley National Park, California, U.S., reached 56.7° Celsius (134° Fahrenheit) on July 10, 1913—the highest temperature ever recorded.
Extremely arid areas, such as occur in the Atacama, Namib, and the central and eastern Sahara, cover about 4% of the Earth's surface, arid about 15%, and semi-arid about 14.6%. In addition, deserts can be classified on the basis of their proximity to the oceans.
Sep 29, 2014 · Importantly, arid regions and drylands are not necessarily hot year round, with continental deserts, for example the Gobi in Mongolia, experiencing extremely low winter temperatures. This article focuses on geomorphic systems, but with relevant linkages to ecology and issues of human-environment interactions.
Aridity is a function of a continuum of environmental factors including temperature, precipitation, evaporation, and low vegetative cover. Aridity indexes are quantitative indicators of the degree of water deficiency at a given location ( Stadler, 1987 ).
