Outflow boundary a downburst. "Gustnadoes", short-lived vertical circulations near ground level, can be spawned by outflow boundaries. Gust fronts create low-level wind shear which can be hazardous to planes when they takeoff or land. Flying insects are swept along by the prevailing winds. As such, fine line patterns within weather radar imagery, associated with converging winds, are dominated by insect returns. At the surface, clouds of dust can be raised by outflow boundaries. If squall lines form over arid regions, a duststorm known as a haboob can result from the high winds picking up dust in their wake from the desert floor.
Fog desert ranges allow for maritime winds to settle in specific geographic areas, which is a common theme in fog deserts. The Andes Mountain range is the land form that divides Chile and Peru into inland and coastal regions and allows for the fog desert to form along the Pacific coast. In the Atacama Desert, plant coverage can be as high as 50% in the center fog zone to as low as no life whatsoever above the fog line. Within arid fog deserts with low precipitation levels, fog drip provides the moisture needed for agricultural development. The diverse sections within a fog
