Editing Squall line (section)

====Wind shear====
[[Wind shear]] is an important aspect of a squall line. In low to medium shear environments, mature thunderstorms will contribute modest amounts of downdrafts, enough to help create a leading edge lifting mechanism – the gust front. In high shear environments created by opposing low level jet winds and synoptic winds, updrafts and consequential downdrafts can be much more intense (common in supercell [[mesocyclone]]s). The cold air [[outflow (meteorology)|outflow]] leaves the trailing area of the squall line to the mid-level jet, which aids in downdraft processes.
