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.
Geography of the European Union
Including overseas territories of member states, the EU includes most types of climate from Arctic to tropical. Meteorological averages for the EU as a whole are therefore not meaningful. The majority of the population live in areas with a Mediterranean climate (southern Europe), a temperate maritime climate (western Europe), or a warm summer continental or hemiboreal climate (in eastern member states).
