WebCold fronts nearly always extend anywhere from a south direction to a west direction from the center of low-pressure areas and never from the center of high-pressure systems. Warm Front A warm front is the leading edge of a relatively warmer air mass replacing a colder air mass. Webatmospheric motion and winds. As soon as a pressure gradient exists, air moves to try to eliminate it by moving air from higher pressure to lower pressure (Fig. 13.1), in accordance with Newton’s Second Law. The pressure gradient force acts at right angles to the isobars, in an attempt to obliterate the pressure gradient.
