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.
Desert bighorn sheep and Wildlife Service to propose a reduction in protected sheep habitat by more than 50%, from . Desert bighorn sheep Desert bighorn sheep ("Ovis canadensis nelsoni") is a subspecies of bighorn sheep ("Ovis canadensis") that is native to the deserts of the USA's intermountain west and southwestern regions, as well as northwestern Mexico. The trinomial of this species commemorates the American naturalist Edward William Nelson (1855–1934). The characteristics and behavior of desert bighorn sheep generally follow those of other bighorn sheep, except for adaptation to the lack of water in the desert. They can go for extended periods of time
