Image Caption: STS049-92-071 - Saharan Duststorm, Algeria-Niger Border
This south-looking, late-afternoon view shows one of the best examples in the Shuttle photo data base of a duststorm. A series of gust fronts, caused by dissipating thunderstorms, have picked up dust along the outflow boundaries. Small cumulus clouds have formed over the most vigorously ascending parts of the dust front, enhancing the visual effect of the front. The storm is moving roughly NNW, at right angles to the most typical path for duststorms in this part of the Sahara (shown by lines of sand on the desert surface in the foreground). Storms such as these can move out into the Atlantic, bringing dust even as far as the Americas on some occasions. Taken May 13, 1992, at 16:43:51 GMT, with a Hasselblad camera, 100-mm lens, and color film.
