MID-LATITUDE WAVE CYCLONE *** a low pressure cell that forms & moves along a front . Counter-clockwise circulation (NH) around the cyclone tends to produce the wavelike deformation of the front. Stages of the Wave Cyclone Life Cycle : Stage 1 : 2 air masses, (a cold & a warm), are set-up along a front & move parallel to it Stage 2: a wave forms & warm air starts to move poleward while cold air moves equatorward Stage 3: cyclonic (counter-clockwise) circulation develops, with general convergence at the surface and uplifting; warm air overrides the cold air (frontal Stage 4: Cold front moving faster than the warm front and begins to overtake it; occlusion begins, forming an Occluded Front Stage 5: full development of an Occluded Front & maximum intensity of the wave cyclone; steep pressure gradient & Strong winds Stage 6: pressure gradient weakens, energy exhausted & system dissipates Your textbook describes 4 stages:
