Answer 5

A squall line is a line of thunderstorms that is generated from the same lifting mechanisms. These may include a cold front, dryline, outflow boundary or a gravity wave. They tend to form in areas where the best instability, lift and moisture is available. A squall line sustains itself by the outflow boundaries it produces. Outflow boundaries form as a result of rain-cooled air being rushed down to the surface and spreading out in all directions. They act as "mini-cold fronts". Throughout the squall lines' lifetime, parts of the line may die out while new cells are formed. They are known to produce very strong straight-line winds. Tornadoes and large hail are not as common though with squall lines.
