A transition zone in the atmosphere where an advancing warm air mass displaces a cold air mass.

The leading edge of a relatively warm air mass which moves in such a way that warm air replaces colder air that moves away from a region. Winds associated with warm frontal activity are usually light [..]

A transition zone between a mass of warm air and the colder air it is replacing.

The leading edge of a warm air mass.

mass of warm air that replaces a mass of cold air.

Any nonoccluded front, or portion thereof, that moves in such a way that warmer air replaces colder air. While some occluded fronts exhibit this characteristic, they are more properly termed warm occl [..]

the front edge of a body of warm air where it meets and rises above a body of colder air.

A long, wedge-shaped boundary caused when a warmer advancing air mass slides over neighboring cooler air parcels. warning coloration

A leading boundary of a warm airmass that is often moving into an area influenced by a cooler airmass. WARNING: A public notice issued by the National Weather Service when a certain hazard (tornado, s [..]

A narrow transitions zone separating advancing warmer air from retreating cooler air. The air behind a warm front is warmer and typically more humid than the air it is replacing. In Canada, it is def [..]

The leading edge of an advancing warm air mass that is replacing a retreating relatively colder air mass. Generally, with the passage of a warm front, the temperature and humidity increase, the pressu [..]

The leading edge of a mass of warmer air that displaces a mass of colder air.

A indeterminate line on which a mass of warm air meets and rises over a mass of colder air. Its approach is usually accompanied by rain.

A front that moves in such a way that warm air replaces cold air.

A transition zone between a mass of warm air and the colder air it is replacing. Also includes: Detached Warm Front.

The leading edge of a warm air mass.

Any non-occluded front which moves in such a way that warmer air replaces colder air.

A transition zone between a mass of warm air and the colder air it is replacing.

The transition zone where a warm air mass overtakes and replaces a colder air mass. Warning

A moving boundary that separates warmer air from cooler air. A warm front is named as such because the warm air is advancing on the cold air. These are not common in mainland Australia but cross TAS regularly during winter.

A front that moves in such a way that warm air replaces cold air.

The boundary between two different air masses where warm air pushes cold air away to bring warmer weather.

The boundary that forms where a warm air mass pushes into a colder air mass.

The leading edge of an advancing warm air mass that is replacing a retreating relatively colder air mass. Generally, with the passage of a warm front, the temperature and humidity increase, the pressure rises, and although the wind shifts (usually from the southwest to the northwest in the Northern Hemisphere), it is not as pronounced as with a col [..]

A narrow zone of transition between relatively warm air that is advancing and relatively cool air that is receding.

The leading edge of an advancing warm air mass that is replacing a retreating relatively colder air mass. Generally, with the passage of a warm front, the temperature and humidity increase, the pressure rises, and although the wind shifts (usually from the southwest to the northwest in the Northern Hemisphere), it is not as pronounced as with a col [..]

The leading edge of an advancing warm air mass

A boundary between warm air and cooler air, when the warm air is advancing and rising over the cooler air. This is usually a more gradual process than a cold front and the rain by comparison is lighter but more continuous over a larger area. Warm fronts are quite rare over south-east Australia because of all the land to the north, but very common f [..]

A transition zone between a mass of warm air and the colder air it is replacing.

A warm-cold air boundary with warm air advancing.

The leading edge of an advancing warm air mass that is replacing a retreating relatively colder air mass. Generally, with the passage of a warm front, the temperature and humidity increase, the pressure rises, and although the wind shifts (usually from the southwest to the northwest in the Northern Hemisphere), it is not as pronounced as with a col [..]

(meteorology) A warm front is the trailing edge of a retreating mass of cold air.
