Climate
The Köppen classification depends on average monthly values of temperature and precipitation. The most commonly used form of the Köppen classification has five primary types labeled A through E. These primary types are A) tropical, B) dry, C) mild mid-latitude, D) cold mid-latitude, and E) polar. The five primary classifications can be further divided into secondary classifications such as rainforest, monsoon, tropical savanna, humid subtropical, humid continental, oceanic climate, Mediterranean climate, desert, steppe, subarctic climate, tundra, and polar ice cap.
Köppen climate classification
The Köppen climate classification scheme divides climates into five main climate groups: "A" (tropical), "B" (dry), "C" (temperate), "D" (continental), and "E" (polar). The second letter indicates the seasonal precipitation type, while the third letter indicates the level of heat. Summers are defined as the 6 month period that is warmer either from April–September and/or October–March while winter is the 6 month period that is cooler.
