This is known as an outflow boundary. Thunderstorms are composed of two main air flows, an updraft and a downdraft. An updraft is a narrow stream of air that pushes upward into a thunderstorm.

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.

WebJul 27, 2024 · An outflow boundary is created when a thunderstorm produces a downdraft of air that crashes into the ground and spreads out, away from the storm. The downdraft consists of rain-cooled air falling from a storm, since it is more dense than the surrounding air. As the colder air sinks and spreads, it causes warm and moist air around the storm to ...
