What are the climate types in North America?

North America spans three zones and has diverse climate types, but most areas have a temperate continental climate. The Arctic coast has a polar climate, and the Pacific coast also has temperate ocean, Mediterranean and tropical desert climates; The Indian Islands and the Central American Isthmus have a savanna climate and a tropical rainforest climate; the Gulf Coast north of the Tropic of Cancer has a humid subtropical monsoon climate. Because the central Great Plains runs from south to north, cold waves and hurricanes have become disastrous weather conditions in North America.
