Although deserts are characterised by dry climates, particular deserts are often dry for different reasons. For instance, deserts like the Gobi are dry because the distance from the coast means that moisture bearing winds do not reach them. In contrast, deserts like the Sahara are dry because of the creation of dry high pressure zones fueled by the climatic conditions in the vast equatorial rainforests.

There are four major factors which help the creation of deserts. Tropical high pressure zones, continentality, rain shadows and cold ocean currents. These factors are considered in the following pages of this NatureExplorer guide.
