The coldfront itself usually contains strong winds, and is often preceded by a squall line containing truly dangerous winds. The horizontal gradient of the buoyancy term always tends to propagate the coldfront. In their studies they assumed that the flow in the coldfront was motionless relative to the moving front. The direction remained fairly constant until it veered to around 220x when the coldfront went through around 1323 hours. Here a curved warm front on the eastern side meets a curved coldfront that follows it. The atmospheric pressure rises as the coldfront passes. As the core of the cyclone passes, the coldfront of a high-pressure zone follows, generally accompanied by a squall line that brings violent and destructive winds. A slow-moving coldfront covered much of the operational area, giving conditions of dense cloud from 700 feet to 15,000 feet. From the Hansard archive Example from the Hansard archive.
