>>1617500Exactly my point, except that it is still not dry enough to be considered a true desert. There are even parts of Wyoming that get 6 inches of rain a year and they are still technically not arid, due to ET rates not exceeding precipitation. Most true deserts lie below 40N parallel. An example of true arid deserts in NA are in parts of AZ, CA, and NV where rainfall can often be less than 3 inches annually and evaporation rates in excess of 140 inches a year.
