Dust Plume by Mali-Mauritania Border17.9N 5.9W
A plume of dust can be seen blowing near the Mali-Mauritania border in this image of western Africa. Most of lies in the southern Sahara, which produces a hot, dust-laden Sudanian savanna zone. The country is mostly flat, rising to rolling northern plains covered by sand.
The country’s climate ranges from tropical in the south to arid in the north, as one can observe from the gradual change from green to yellow moving from south to north. Most of the country receives negligible rainfall; droughts are frequent. Late June to early December is the rainy season, however, and during this time, flooding of the Niger River is common, creating the Inner Niger Delta (partially visible by the left edge).
