The Andes prevent rain-bearing clouds from the Pacific Ocean from moving in, while its latitude puts it in a band of the sub-tropical high pressure belt keeping the region dry.

Patagonia is located between the subtropical high pressure belt and the subpolar low pressure zone, meaning it is exposed to westerly winds that are strong, since south of 40�S there is little land to block these winds.

Individual dust storms in the Bodele were also shown in this research to coincide with a major strengthening of the Bodele Low Level Jet which, in turn, is associated with the ridging of the Libyan High, a feature of the subtropical High Pressure belt.
