Within the Atlas Mountains, rainfall is not distributed evenly. Precipitation is significantly more plentiful in the Tell Atlas than in the Saharan Atlas, with the highest amounts recorded in the northeastern sections of the range.1

Specifically, the highest rainfall is found east of the Tell Atlas. A notable example is the Kroumirie mountains, where the town of ʿAyn ad-Darāhim receives approximately 60 inches (1,524 millimetres) of rain annually. In contrast, areas such as the Anti-Atlas Mountains receive no more than 17 inches per year. Additionally, within any individual massif, slopes with a northern exposure receive more rainfall than those facing south.1
