Intro

Humidity in fog air is above 95%. One way for fog to form in deserts is through the interaction of hot humid air with a cooler object, such as a mountain. When warm air hits cooler objects, fog is composed. Another way for fog to be form in deserts, is if the desert is close to the coast and that coast has some cold currents running through it. When air heated in the desert land blows towards the cool water in the ocean, it gets cooler and fog is formed. The cool fog would then get blown inland by the ocean breeze. Fog is mainly formed in the early morning or after sunset.

Ecology of Fog Deserts:

There are certain types of plants and animals that live in fog deserts. Almost all of them depend on water contained in the fog for their survival which is evident in the way they have developed adaptations to collect water. An example would be the Stenocara beetle that lives in the Namib Desert; the beetle climbs the sand dunes when the humid wind is blowing from the ocean and transforms fog into drops of water. An example of a plant would be Welwitschia which also grows in the Namib desert and grows only two leaves through its life which can be up to 1000 years. The leaves have large pores to help it absorb water from the fog forming on them. People also living in the Namib depend on techniques to collect water from fog. A lot of technologies are being developed to help extract water from desert air. Fog harvesters are undergoing improvements based on our observations of the adaptations of some of the beings in fog deserts like the Stenocara beetle. Devices being developed to extract water from air desert use Metal Organic Framework crystals to capture and hold water molecules when exposed to air flow at night. In the morning, air flow is cut and the water collected previous night is then vaporized by exposure to sunlight and then condensed into liquid water when it hits the cooler condenser.
