One slide requires AQA AS Geography: Student’s Guide by Redfern, Barker and Skinner (). Cause: Cause These deserts are “distant” from major water-vapor sources (e.g., evaporation from oceans), and may be near the middle of continents. During the transit of the air over large distances, much water vapor gets precipitated out, causing the air to be dry when it gets to the interior of continents.

Less PPT. ↓ Soil fertility; soil degradation & Soil aridity. Human factors. + “If the climatic factors are said to be the main causes of desertification, then human. Causes of Aridity. Causes of Aridity (2) – Cold Ocean Currents: Several deserts lying along western coasts of continents owe their formation to cold ocean surface currents. Air blowing towards the shore, chilled by contact with cold water, produces a layer of fog. This heavy fog drifts onto land. “Dust events as a risk factor for daily hospitalization for respiratory and cardiovascular diseases in Minqin, China.” Atmospheric Environment 41, Minqin, China * Smoke plumes from wildfires in Queensland and northern NSW indicate dominant wind directions; dust source in . The causes and distribution of deserts. Rainshadow and continentality Air descending from mountainous areas warms and dries by compression, little rainfall forms and aridity is the result.

Why associations with measures of aridity? Drought stress common cause mortality and annual yield loss Slideshow. Aridity can also result from the lack of storm systems, the mechanisms that cause convergence, create unstable environments, and provide the upward movement of air which is necessary for precipitation. At last! I have finished this extremely long and carefully edited PowerPoint and accompanying worksheet explaining the causes of aridity, well, 2 of them at least! I do plan to do another lesson on ocean currents and mountains for next week so please let me know if you would like those too. Causes of Aridity 1. Atmospheric high pressure zones (Hadley Cells) Earth’s atmosphere moves in general, somewhat predictable patterns that are largely driven by the sun’s rays and the earth’s rotation. At the Equator, the sun’s rays are perpendicular with the Earth’s surface; solar heating is intense. Cause: Cause These deserts are “distant” from major water-vapor sources (e.g., evaporation from oceans), and may be near the middle of continents.
