Editing Squall line (section)

====Pressure perturbations====
Pressure perturbations around thunderstorms are noteworthy. With [[buoyancy]] rapid within the lower and mid-levels of a mature thunderstorm, updraft and downdraft create distinct mesocenters of pressure. As thunderstorms organized in squall lines, the northern end of the squall line is commonly referred to as the cyclonic end, with the southern side rotating anticyclonically (in Northern hemisphere). Because of the [[Coriolis force]], the northern end may evolve further, creating a "comma shaped" wake low, or may continue in a squall-like pattern. The updraft ahead of the line create a [[mesolow]] too while the downdraft just behind the line will produce a mesohigh.
