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.
Sechura Desert from the Andes support intensive irrigation-based agriculture. Within Peru, the desert is described as the strip along the northern Pacific coast of Peru in the southern Piura and western Lambayeque regions, and extending from the coast 20–100 km inland to the secondary ridges of the Andes Mountains. At its northern end near the city of Piura, the Sechura Desert transitions to the Tumbes-Piura dry forests ecoregion. Comprising much of eastern Lambayeque Region, this habitat is composed of equatorial dry forests. The total area of the Sechura Desert is 188,735 km². While a desert, the Sechura has been subject to flooding
