arid climate

arid climate  

A climate where rainfall is insufficient to support appreciable amounts of vegetation. Arid climates occur in regions subject to persistent high pressure, such as those beneath the subtropical ...
blowing dust/sand

blowing dust/sand  

A term used in synoptic meteorology to indicate that dust or sand is being transported by the wind, at heights greater than 1.5 m, but that visibility is greater than 1 000 m. See drifting dust/sand; ...
