Freebase(0.00 / 0 votes)Rate this definition: Arid. A region is arid when it is characterized by a severe lack of available water, to the extent of hindering or preventing the growth and development of plant and animal life. Environments subject to arid climates tend to lack vegetation and are called xeric or desertic.
I've been writing about deserts for awhile, but it seems that it might be a good idea to define what a desert is.The most basic definition is that a desert is an area that is moisture deficient; more water evaporates than is received.ne of the characteristics of deserts is that they have large temperature fluctuations due to the lack of humidity. Daytime and nighttime temperatures may vary by over 50 degrees Fahrenheit (10 deg C). (Keep that in mind if you're packing for a trip to the desert!). Deserts are not necessarily hot.
