0 the weather condition in which a moving mass of cold air pushes into a mass of warm air resulting in a fall in temperature
If the observer is only a short distance south of the low-pressure centre, then the cold front would follow rapidly.
The cold front 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 cold front.
In their studies they assumed that the flow in the cold front was motionless relative to the moving front.
The direction remained fairly constant until it veered to around 220x when the cold front went through around 1323 hours.
Here a curved warm front on the eastern side meets a curved cold front that follows it.
The atmospheric pressure rises as the cold front passes.
As the core of the cyclone passes, the cold front of a high-pressure zone follows, generally accompanied by a squall line that brings violent and destructive winds.
