Concept Explanation
 

High-Latitude Climates Of Earth

Group III: High-Lattitude Climates: These climatic regions are dominated by polar and arctic air masses. The two source regions of these air masses are Canada and Siberia. Such climates are not found in the Southern hemisphere due to narrowness of the continents in this hemisphere. Arctie and Polar air masses meet each other at 60° latitude.
