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.
Calansho Desert Calansho Desert Calansho Desert (Sarīr Kalanshiyū, Calansho Serir) is a desert in eastern Libya in Al Wahat District. It is part of the Sahara and has a hot desert climate (BWh). It is primarily rocky in the north and center, but forms part of the "Great Sand Sea" to the east and contains the Calanshio Sand Sea to the south. As Sarīr is the only settlement in the Sarīr Kalanshiyū. The Sarir oil field is located in the western Sarīr Kalanshiyū. It is currently thought that the ancestral Nile flowed through what is now the Calansho Desert during the Miocene.
