3. How did Köppen divide the different climates? • Köppen divided the Earth's surface into climatic regions that generally coincided with world patterns of vegetation and soils. • The Köppen system recognizes five major climate types based on the annual and monthly averages of temperature and precipitation. • The types are designated by the capital letters: • A • B • C • D • E • H

Subgroups Subgroups are designated by a second, lower case letter which distinguish specific seasonal characteristics of temperature and precipitation. Later, a third letter was added to the code, to further denote the variations in climate.
