Cloud Types and Formation

Clouds over Bir el Ater, Algeria, display a captivating blend of towering cumulus and widespread stratus formations. Cumulus clouds, characterized by their puffy appearance, often grace the skies during the early morning and midday hours, adding a dramatic depth to the landscape. As the day progresses, these clouds may transform into stratocumulus formations, featuring a mix of flat and round structures.
