Based on precipitation alone, hyperarid deserts receive less than 25 mm (1 in) of rainfall a year; they have no annual seasonal cycle of precipitation and experience twelve-month periods with no rainfall at all. ... These regions feature a semi-arid climate and are less extreme than regular deserts.
The hyper-arid zone (arid index 0.03) comprises dryland areas without vegetation, with the exception of a few scattered shrubs. True nomadic pastoralism is frequently practiced. Annual rainfall is low, rarely exceeding 100 millimeters.

Dry climates receive very little rainfall. They also have high rates of evaporation. This makes them even drier.
Description of the equatorial climate They are hot and wet all year round – this creates a humid climate. The annual rainfall is high as it rains almost every day. The temperatures are constant all year round – the temperature range is usually only a few degrees. There are no seasons.
The topography of an area can influence the weather and climate. ... Mountainous areas tend to have more extreme weather because it acts as a barrier to air movements and moisture. One side of mountain can be dry while the other side is full of vegetation. Mountains can cause a physical barrier to rain clouds.

Desertification affects about 46 percent of Africa. ... Agriculture in Africa tends to result in low productivity, as most of the land is characterized as a semi-desert. Clearing the land of trees also reduces the structure of the soil. Coupled with wind erosion, the topsoil blows away and leaves a desert-like land.
This situation is acute in Somalia, Ethiopia, Djibouti and Kenya, where the combination of weak governments and a lack of annual rains linked to climate change are driving desertification levels.
