Describe the formation of a cP air mass and then discuss the typical weather it produces and the changes it undergoes as it travels across the Great Lakes and moves southward

Question

What will be an ideal response?

Answer 1

cP air masses form only in the Northern Hemisphere and are most developed in winter and cold-weather conditions. The cold, dense air of cP air masses displaces moist, warm air in its path, lifting and cooling the air. The area covered by cP air in the winter experiences cold, stable air. As a cP air mass moves, it is modified, producing snowbelts. As a cP passes over the Great Lakes, it absorbs heat energy and moisture from the lakes and becomes humidified. This produces heavy snowfall downwind.
