Table 2.2.
Köppen's major climates based upon four major temperature regimes, derived from monthly mean temperatures, monthly
precipitation and mean annual temperature: one tropical, two mid-latitudes and one polar. The second division is based on moisture
availability. The system does not completely agree with natural vegetation and climate, and frequently the boundaries are rigidly
interpreted.
