Koppen Climate Classifications

Koppen climate classifications give information about temperature, precipitation and vegetation for a specific area. Study the map below to explore these different climate zones.

Group Description Temperature Precipitation Extent
A Tropical Moist Climates Mean Temperature: above 64°F Annual Rainfall: over 59" From Equator to between 15° and 25°
B Dry Climates Deficient most years, evaporation exceeds precipitation Extend from 20° to 30° latitude in large continental regions, often surrounded by mountains
C Moist Subtropical Mid-Latitude Climates Humid, mild winters with mean temperatures below 64°F but above 27°F On the eastern and western regions of most continents from about 25° to 40°
D Moist Continental Climates Mean winter temperatures are below 27°F, mean summer temperatures above 50°F North of moist subtropical mid-latitude climates
E Polar Climates Year round temperatures are below 50°F Northern coastal areas of North America and Eurasia, Greenland and Antarctica
