WebA gust front is the leading edge of cool air rushing out from a thunderstorm. A gust forms when dense rain- or ice-cooled air rapidly sinks (downdrafts) within a thunderstorm. This … 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 duststor…
WebA sandstorm is described as a natural phenomenon that occurs when a strong wind, such as a gust front, blows fine sand particles and dust from a dry surface. These particles become suspended in the air, causing erosion where they initially were. The wind drops these particles in another place where silt is formed.
