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 ecology Desert ecology Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organism populations, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions which are generally associated with warm temperatures, however cold deserts also exist. Deserts can be found on every continent, with the largest being located in Antarctica, the Arctic, Northern Africa, and the Middle East. Deserts experience a wide range of temperatures and weather conditions. They can be classified into four types: hot, semiarid, coastal,
