Saharan brush strokes
Windswept dunes on one of the sunniest regions on Earth.
The Ténéré region in north-eastern Niger is one of the hottest and driest regions in the Sahara desert, with average maximum temperatures above 40 °C between May and September.
The region’s geography largely consists of planes with sand dunes (ergs) that are oriented perpendicular to the persistent north-easterly wind (Harmattan). This image taken on 6 March 2016 shows the extensive sand dunes as yellow areas in the upper image part, with the sand and dust being transported towards the southwest, visible as faint feather-like structures.
