Gust Front

Gust Fronts resembles the passage of a cold front A gust front is a boundary that separates a cold downdraft of a thunderstorm from warm, humid surface air. Its passage at the surface resembles a cold front.

gust front"The leading edge of a mesoscale pressure dome separating the outflow air in a convective storm from the environmental air.

Gust Front The leading edge of the thunderstorm downdraft air. Most prominent beneath the rain-free base and on the leading edge of an approaching thunderstorm. Usually marked by gusty, cool winds.

Gust Front - a boundary between cold air from the thunderstorm downdraft and warm, humid surface air Gustnado (or Gustinado) - [Slang] a small tornado, usually weak and short-lived, that occurs along the gust front of a thunderstorm ...

Gust Front: The leading boundary of relatively cold air flowing out of a thunderstorm, usually producing gusty winds, a noticeable wind shift and temperature drop when the gust-front passes (similar to a cold front).

Gust Front 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.

GUST FRONT - A miniature cold front caused by fallout (cold descending air) from a thunderstorm that hits the ground and spreads rapidly.

GUST FRONT- It is the leading edge of thunderstorm outflow. Often cooler and gusty air follows behind the gust front. HAZE (H)- Dust, salt and other particles that restricts horizontal visibility.

GUST FRONT - The leading edge of the downdraft from a thunderstorm. H HAIL - Precipitation of small balls or other pieces of ice (hailstones) falling separately or frozen together in irregular lumps.

Gust Front - The leading edge of gusty surface winds from thunderstorm downdrafts; sometimes associated with a shelf cloud or roll cloud. See also downburst, gustnado, outflow boundary.

Gust Front - The boundary separating the cold downdraft from a thunderstorm and the relatively warm, moist surface air. Lifting along this boundary may initiate the development of thunderstorms.

Gust front- A windshift line that is caused by thunderstorms and other convection. The line acts like a front in that it can cause pressure changes, gusty winds and wind shear. H ...

Gust Front- The leading edge of the downdraft from a thunderstorm. A gust front may precede the thunderstorm by several minutes and have winds that can easily exceed 80 mph.

GUST FRONT - The leading edge of cooler outflow air from a thunderstorm. A thunderstorm dying from downdrafts killing its updraft components is sometimes said to be GUSTING OUT. A left over gust front can also be called an OUTFLOW BOUNDARY.

GUST FRONT The leading edge of the cool, gusty surface winds produced by thunderstorm downdrafts. Sometimes confused with an outflow boundary. Related term: first gust ...

A gust front which wraps around a mesocyclone, cutting off the inflow of warm moist air to the mesocyclone circulation and resulting in an occluded mesocyclone. WRCC Western Regional Climate Center ...

Wrapping Gust Front - A gust front which wraps around a mesocyclone, cutting off the inflow of warm moist air to the mesocyclone circulation and resulting in an occluded mesocyclone.

They are often along and behind cold fronts and gust fronts, being associated with cool moist air, such as an outflow from a thunderstorm. When observed from a distance, they are sometimes mistaken for tornadoes.

Triple point also may refer to a point on the gust front of a supercell, where the warm moist inflow, the rain-cooled outflow from the forward flank downdraft, and the rear flank downdraft all intersect; ...

ScudSmall, ragged, low cloud fragments that are unattached to a larger cloud base and often seen with and behind cold fronts and thunderstorm gust fronts. Such clouds generally are associated with cool moist air, such as thunderstorm outflow.

Each cell generates a cold air outflow and these individual outflows combine to form a large gust front. Convergence along the gust front causes new cells to develop every 5 to 15 minutes. The cells move roughly with the mean wind.

Tstorms: Gust Front. 9. Tstorms: Hail. Hail Shaft: Hail Streak. 10. Tstorms: Hail: One of the largest hailstone fell in Nebraska in 1928. It was 17 inches around & weighed 1.5 lbs. 11. Tstorms: Hail Size: Gulfball. Baseball. Grapefruit. 12.

Gustnado - It's just a gust front tornado. It's a small and weak tornado that occurs along the gust front of a thunderstorm and doesn't stay on the ground for long periods of time.

FIRST GUST Another name for the initial wind surge observed at the surface as the result of downdrafts forming the leading edge or gust front of a thunderstorm. Related term: gust front ...

Arcus - A low, horizontal cloud formation associated with the leading edge of thunderstorm outflow (i.e., the gust front). Roll clouds and shelf clouds both are types of arcus clouds.

DUST PLUME A non-rotating "cloud" of dust raised by straight-line winds. Often seen in a microburst or behind a gust front. If rotation is observed, then the term dust whirl or debris cloud should be used.

P1620 Pressure jump A sudden pressure change, usually a rise, associated with the passage of a thunderstorm, squall or gust front, and indicated by a steep vertical line on a barogram.

In addition, the downdraught will hit the surface and spread horizontally as a cold density current (gust front).

The third type is the squall line composed of a line of convective clouds which share a common gust front along the leading edge (sometimes seen as a wall cloud).

Mesoscale winds are those which act on a local scale, such as gust fronts. At the smallest scale are the winds which blow on a scale of only tens to hundreds of metres and are essentially unpredictable, such as dust devils and microbursts.
