Along a storm's gust front, which is the leading edge of rain-cooled air fanning out along the ground, small vortices called gustnadoes can spin up.
12.
These kind of lines will have a very characteristic undulating pattern caused by the interference of the gusts fronts coming from different parts of the line.
13.
A sharp, strong gust front will cause the lowest part of the leading edge of a shelf cloud to be ragged and lined with rising fractus clouds.
14.
Fast moving gust fronts may eventually decelerate and become slow moving or stationary outflow boundaries with the characteristic " agitated area " of cumulus fields previously mentioned.
15.
A derecho ( " from Spanish " : " gust front, except that the wind is sustained and generally increases in strength behind the " gust " front.
16.
Three people were injured in Deerfield, Massachusetts when a hot air balloon got caught into the winds of the derecho gust front and blew the balloon into a tree.
17.
The cooled air that is dragged earthward by the falling raindrops can often be felt before the storm as a rush of cool air that meteorologists call a gust front.
18.
In low to medium shear environments, mature thunderstorms will contribute modest amounts of downdrafts, enough to turn will aid in create a leading edge lifting mechanism the gust front.
19.
SPANDAR s sensitivity with its dish antenna can detect small changes in the refractive index of air caused by sea breeze fronts, gust fronts, and various forms of clear air turbulence.
20.
Finally, in any type of thunderstorms, the surface cold pool of air associated the downdraft will stabilize the air and form a cloud free area which will end along the gust front.
