Topic: Front meteorology

	Surface weather analysis - Wikipedia, the free encyclopedia
		Fronts in meteorology are the leading edges of air masses with different density (e.g., air temperature or humidity).
		Cold fronts are often closely associated with low pressure systems, normally lying at the leading edge of high pressure systems and, in the case of the polar front, at approximately the equatorward edge of the high-level polar jet.
		Fronts are the principal cause of significant weather.

		Meteorology is the scientific study of the atmosphere that focuses on weather processes and forecasting.
		Meteorology, climatology, atmospheric physics, atmospheric dynamics, and atmospheric chemistry are sub-disciplines of the atmospheric sciences.
		At this time in Norway a group of meteorologists led by Vilhelm Bjerknes developed the model that explains the generation, intensification and ultimate decay (the life cycle) of midlatitude cyclones, introducing the idea of fronts, that is, sharply defined boundaries between air masses.

	HighBeam Encyclopedia - front
		FRONT [front] in meteorology, zone of transition between adjacent air masses.
		If a cold air mass is advancing to replace a warmer one, their mutual boundary is termed a cold front; if the reverse, then the boundary is termed a warm front, whereas a stationary front indicates that no relative advance of either air mass is occurring (see illustration).
		An occluded front is one in which a warm front has been completely undermined by cold air and is therefore positioned aloft.

	Meteorology - MSN Encarta
		The passage of the front is often accompanied by the heaviest precipitation and the strongest and gustiest winds.
		Occluded fronts appear on weather maps as a solid purple line with alternating triangles and half circles, both pointing in the direction toward which the front is moving.
		Such fronts are common at the boundary between the midlatitude cell and the polar cell of the three-cell model.

	Synoptic scale features
		In section 4 we established that the Antarctic front is the boundary region between the intensely cold Antarctic polar continental air and the warmer, moister polar maritime air; and that the polar fronts are the major frontal regions of the Southern Hemisphere, mixing between polar air, mid-latitude air and returning tropical air.
		The mobile fronts which develop with the extratropical cyclones are typically one nautical mile deep at the surface but expanding with height, 150 to 400 nm wide and moving at 20 knots.
		Cold fronts, where colder, denser air is pushing under semi-stationary warmer air, has a typical slope of 1:60 but the warmer air is tending to ascend slantwise across the slope of the cold front.

		] The line of intersection of a front (frontal surface) with a specified surface in the atmosphere, usually a constant-pressure surface; with respect to only one surface, this line is usually called the front.
		] The forced ascent of the warmer, less-dense air at and near a front, occurring whenever the relative velocities of the two air masses are such that they converge at the front.
		] The presentation of a front, on a synoptic chart, as a frontal zone; that is, two lines, rather than a single line, are drawn to represent the boundaries of the zone; a rare usage.

		Cold-occluded front: advancing cold front rides under the warm front, and weather along front is similar to cold front Warm-occluded front: advancing cool front is slightly warmer than cold air mass under the warm front, so it rides over the warm front, and the weather along the front is similar to warm front.

		Fronts are also identified: a 'classical' depression appearing in the western North Atlantic, with an identifier 'A', will have its warm front labelled 'A', and its cold front 'B'.
		Fronts are drawn with heavy solid lines, distinguished by solid 'triangles' for cold fronts, solid 'bobbles' for warm fronts, and a mixture of the two for an occlusion.
		If the front is significantly weakening (frontolysis) then a cross hatch is placed across the frontal line between the triangles/bobbles, and if a front is considered to be forming (frontogenesis) then the solid line appears broken.

		Because of the distributed nature of primary emissions along the Front Range and the importance of moisture to many chemical processes, characterization of horizontal transport and vertical mixing processes as well as moisture sources, is essential to understanding the spatial and temporal evolution of Front Range pollution episodes.
		Thus, documenting the meteorology of the Front Range during NFRAQS is critical to meeting the goals listed above and interpreting the results from the research that addresses them.
