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 Combat Boot Desert Combat Boot Desert Combat Boots are type of combat boot designed specifically for use in humid or arid regions for desert warfare, where a traditional or standard issued black leather combat boot might be deemed uncomfortable or unnecessary. Like jungle boots, desert boots may implement similar designs; such as nylon canvas sides, speed lacing, and drainage vents on the instep. Boots made for desert warfare may commonly come in colors such as tan or beige, and range from dark to lighter versions of the two. While the history of the desert boot can trace its lineage back to the
