Explanation:

Wisconsin and the upper Midwest are influenced by continental polar air masses which bring cold, dry air. Maritime tropical air masses also play a role as they bring warm, moist air. Continental polar air masses are from cold, dry continental regions (like Canada) and maritime tropical air masses are from warm, moist oceanic regions (like the Gulf of Mexico). These two air masses interact to shape the climate of the area.

continental polar, maritime tropical
