The discontinuity at the forward edge of and advancing cold air mass that is displacing a warmer and often higher in moisture air mass
The leading edge of an advancing cold air mass that is under running and displacing the warmer air in its path Generally, when a cold front passes the temperature and humidity decrease, the pressure rises, and the wind shifts from southwest to northwest Precipitation is usually along or ahead of the front in the form of thunderstorms
The boundary between a cold air mass that is advancing and a relatively warmer airmass Generally characterized by steady precipitation followed by showery precipitation
The leading edge of an advancing cold air mass that is under running and displacing the warmer air in its path Generally, with the passage of a cold front, the temperature and humidity decrease, the pressure rises, and the wind shifts (usually from the southwest to the northwest in the Northern Hemisphere) Precipitation is generally at and/or behind the front, and with a fast-moving system, a squall line may develop ahead of the front
The leading edge of a relatively cold air mass that displaces warmer air Following a cold front passage, westerly winds of 10 to 20 mph, or more, often continue for 12 to 24 hours
The leading edge of a relatively cold air mass that displaces warmer air The heavier cold air may cause some of the warm air to be lifted If the lifted air contains enough moisture, the result may be cloudiness, precipitation, and thunderstorms If both air masses are dry, no clouds may form Following the passage of a cold front in the Northern Hemisphere, westerly or northwesterly winds of 15 to 30 or more miles per hour often continue for 12 to 24 hours
Used in meteorology to describe a mass of cold air moving toward a mass of warm air Strong winds and rain typically accompany a cold front
The leading edge of a relatively cold air mass that displaces warmer air The heavier cold air may cause some of the warm air to be lifted If the lifted air contains enough moisture, the result may be cloudiness, precipitation, and thunderstorms If both air masses are dry, no clouds may form Following the passage of a cold front in the Northern Hemisphere, westerly or northwesterly winds of 15 to 30 mph often continue for 12 to 24 hours
A transition zone in the atmosphere where an advancing cold air mass displaces a warm air mass
The leading portion of a cold atmospheric air mass moving against and eventually replacing a warm air mass; cold air
The boundary between a cold air mass that is advancing and a relatively warmer air mass Generally characterized by steady precipitation followed by showery precipitation
