Detailed explanation-1: -Expert-Verified Answer. The area that is the most common source region for cold, dry air masses that move over New York State is central Canada. These cold, dry air masses are called Continental polar (cP) or continental arctic (cA) air masses.

Detailed explanation-2: -Generally two types of air masses impact New York state weather: warm and humid air from the southwest and a cold and dry air from the northwest. Upstate New York has warm summers and long and cold winters with significant snowfall.

Detailed explanation-3: -The main source regions are the high pressure belts in the subtropics (giving rise to tropical air masses) and around the poles (the source for polar air masses).

Detailed explanation-4: -3. Continental air masses form over continents. Humidity levels within these air masses are low. Continental air masses can develop in either polar or tropical regions.

Detailed explanation-5: -An air mass that is warm and humid would be called a maritime tropical air mass. An air mass that is humid, develops over water, taking some water molecules with it as it forms. These air masses can be described as maritime.
