This process is most efficient when the horizontal voritcity of the cold pool versus the enivornmental shear is the same because ... squall line to increase damaging wind potential. Directional shear isn’t as prevelant in the spring cases, but speed shear is very strong with shear WebSquall Lines. By definition, squall lines are clusters of thunderstorms that have a prominent, relatively linear signature on images of radar reflectivity. While squall lines can produce any kind of severe weather, they most prominently produce damaging straight-line winds. The convection in a squall line tends to be relatively narrow, while ...
