Document Summary

The climate change of the great lakes is affected by three factors: Location of the basin within a large continental landmass. The movement of the air from the from west to east. Changeable weather of the region is result of alternating flows of warm, humid air from the gulf of mexico and cold, dry air from the arctic. North region of the great lakes receives cold, dry air from northwest canada. Temperature inversions: a change in temperature is much higher than normal when dropping in altitude. This causes pollutants to stay trapped under the inversion. In the winter the great lakes is affected by two major air masses. Arctic air mass from the northwest: cold, dry air moving in from the northwest, travels above the great lakes where it collects moisture from the warm body of water, and then hits land where it falls as precipitation.
