How much snow does a desert get a year?

The amount of snow a desert receives would depend upon where the desert is located. Some deserts never, or rarely, receive snow. Others my receive a few inches of snow each year that, usually, is quickly melted or evaporated. The qualifying factor is that the region receives less than 10 inches (250 mm) of precipitation (rain and melted snow) per year on average. Since 10 inches of snow equates to about 1 inch of rain, a desert could, theoretically receive about 100 inches (250 cm) of snow and still be considered a desert.
