[18] [19] It is located in the horse latitudes under the subtropical ridge, a significant belt of semi-permanent subtropical warm-core high pressure where the air from the upper troposphere usually descends, warming and drying the lower troposphere and preventing cloud formation.

As a result, they coined the term "Middle Egypt" for the stretch of river between Cairo and the Qena Bend. [3]
