desert biome tropical desert biome 2013-04-07T14:28:08Z A tropical desert biome is a desert biome which has communities adapted to temperatures above a monthly average of 18 degrees Celsius, high daily temperature ranges of approximately 20 degrees Celsius, very high insolation due to inhibited cloud formation, and very low precipitation. Tropical desert biomes located near coasts with cold upwellings may have cooler temperatures and reduced insolution due to fog. ENVO ENVO:01000183 ORCID:0000-0002-4366-3088 Preliminary definition. The semantics and definitions of "mediterranean", "subtropical", "tropical", "temperate", "polar", and similar climate types may be transferred to an "environmental condition" class once the semantics of this class have been established.
