Notice the size difference. Notice the size difference. Fronts Fronts Cold front a front that separates warm and cold airmasses, and the cold air is advancing and lifting the warm air Warm front a boundary where the cold air is retreating and the warm air is advancing. Stationary front a boundary that separates cold and warm airmasses, where neither airmass is advancing nor retreating. Occluded front a boundary between cold and colder airmasses with warm air aloft Dry line a front characterized by sharp moisture differences rather than sharp temperature differences. Upper level front an airmass boundary that is present aloft but not at the surface Classical Model Classical Model 1. Background Stage: There is boundary between cP and mT airmass in mid-latitude (Baroclinic Zone). 2. Perturbation Stage: Along this boundary a counter- clockwise circulation can set up at the surface, which acts to take warm air up from the south and cold air down from the north. This is called cyclogenesis. Classical Model Classical Model 3. Mature Stage...
