arid climate

Show Summary Details

Quick Reference

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 anticyclones, or where topography blocks the passage of moisture-bearing systems, as with the Gobi Desert in Central Asia. Technically, the high Antarctic plateau has an arid climate, because of its extremely low precipitation.
