WebDec 9, 2024 · Forcing mechanisms include fronts (warm front, cold front) and outflow boundaries (small-scale cold fronts produced by individual thunderstorms), surface wind convergences, orographic lift, and upper-level forcing. We will go into much more detail about the initiation of convection (storm initiation) in one of the future tutorials. An outflow boundary, also known as a gust front, is a storm-scale or mesoscale boundary separating thunderstorm-cooled air (outflow) from the surrounding air; similar in effect to a cold front, with passage marked by a wind shift and usually a drop in temperature and a related pressure jump. Outflow … See more An outflow boundary, also known as a gust front or arc cloud, is the leading edge of gusty, cooler surface winds from thunderstorm downdrafts; sometimes associated with a shelf cloud or roll cloud. A pressure jump is … See more At ground level, shelf clouds and roll clouds can be seen at the leading edge of outflow boundaries. Through satellite imagery, an arc cloud is visible … See more • Density • Derecho • Gustnado • Haboob • Heat burst See more A microburst is a very localized column of sinking air known as a downburst, producing damaging divergent and straight-line winds at the surface that are similar to but distinguishable from tornadoes which generally have convergent damage. … See more 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 … See more • Outflow boundary over south Florida MPEG, 854KB See more
