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 rainbow-skink Desert rainbow-skink The desert rainbow-skink ("Carlia triacantha") is an Australian skink in the genus "Carlia", commonly known as four-fingered skinks, from the subfamily Lygosominae. It is native to desert woodland regions throughout most of the Northern Territory, the north of Western Australia, and the far north-west of South Australia. It was originally classified as "Leiolopisma triacantha", and is sometimes known as the three-spined rainbow-skink. The desert rainbow-skink is on average long, excluding the tail. It is characterised by three keels or spines on the dorsal scales. It is typically a mid-brown to grey-brown colour with less pigmentation on the ventral
