This means that there are special climatic conditions there. Such deserts are formed where the coasts of the continent are washed by a cold ocean current, under the influence of which fogs form over the desert. They are the only provider of moisture in this area, as rainfall there is sporadic.
In addition to the Atacama Desert, the Namib Desert, located mainly in Namibia in southwestern Africa on the Atlantic coast, is another fog desert.
The Atacama is the largest fog desert in the world.
