The location of deserts is dependent on two factors, latitude and global wind patterns. Most deserts are located between 15' and 35' latitude, both north and south of the equator. In terms of global wind patterns, most deserts are located within the Southeastern and Northeastern trade winds belt.
A Desert is defined as a region that has less than 254 mm (10 in) of annual rainfall or precipitation. Antarctica can be classified as a desert by this definition. In the interior of the continent the average annual precipitation (in *equivalent of water) is only about 50 mm (about 2 in), less than the Sahara. Along the coast, this increases, but is still only about 200 mm (8 in) equivalent of water.
