A miniature cold front created by the downdraft of a large thunderstorm as the dense, rain-cooled air spreads outward beneath the thunderstorm. Gust fronts can produce strong, gusty, damaging surface winds, and often serve as a triggering mechanism for new thunderstorms.
The front created when downdraft or downburst air reaches the ground and spreads out. These have been observed to be 100 to 1000 m deep, 5 to 100 km wide, last for 2 to 20 minutes, and spread with speeds of 5 to 15 m/s. Gust fronts are also capable of triggering new thunderstorms as the air in the boundary layer is forced to rise over the advancing front.
A boundary found ahead of a thunderstorm that separates cold storm downdrafts from warm humid surface air. Winds in this phenomenon are strong and fast.
the leading edge of a thunderstorm's downdraft air that is most prominent beneath the rain-free base and the leading edge of a thunderstorm; this gust front may precede the thunderstorm by several minutes and have winds that can easily exceed eighty miles an hour.
Formed when the down draft and rain-cooled air of a thunderstorm reach the ground, and then spread out along the ground. Usually marked by a sudden wind shift, sharply falling temperatures, and possibly heavy downpours and/or hail. If two or more of these gust fronts intersect each other, a new thunderstorm could possibly develop. Sometimes it is associated with a shelf cloud or roll cloud. Also, see downburst, gustnado, and outflow boundary.
The leading edge of a downdraft associated with a thunderstorm which is marked by a sudden wind shift, sharply falling temperatures and possibly heavy downpours and/or hail.
The leading edge of gusty surface winds from thunderstorm downdrafts. Passage of the gust front is usually marked by cool, gusty winds. The gust front often precedes the precipitation by several minutes.
A boundary that separates a cold down draft of a thunderstorm from warm, humid surface air. On the surface its passage resembles that of a cold front. It is not a "true" frontal boundary.
A boundary separating downdraft air from a thunderstorm and the surrounding environmental air. Air tends to be cool and gusty behind the gust front.
The leading edge of the thunderstorm downdraft air. The gust front is most prominent beneath the rain-free base and on the leading edge of an approaching thunderstorm. It is usually marked by gusty cool winds, and sometimes blowing dust. The gust front often precedes the thunderstorm precipitation by several minutes. The shelf or roll cloud sometimes accompanies the gust front, especially when the gust front precedes a line of thunderstorms.
a boundary between cold air from the thunderstorm downdraft and warm, humid surface air
The leading edge of the downdraft from a thunderstorm.
The leading edge of a mass of cool, gusty air that flows from the base of a thunderstorm and spreads along the ground in advance of the thunderstorm.
The leading edge of the downdraft outflow ahead of a thunderstorm.
The leading edge of gusty surface winds from thunderstorm downdrafts; sometimes associated with a shelf cloud or roll cloud. See also gustnado or outflow boundary.
The leading edge of the cool, gusty surface winds produced by thunderstorm downdrafts. Sometimes confused with an outflow boundary. Related term: first gust
