Areas that experience hot desert climates are found within the 300 N … Hence, there is water scarcity. The desert is very dry and often hot. A biome is a major community of plants and animals that are adapted to specific conditions. Other isotherms used to differentiate desert climates are 00C or an average temperature of -30C during the coldest month. Most deserts are located between 15' and 35' latitude, both north and south of the equator. The tropical seasons are divided into two: wet and dry.
