Note that some of the climate classes (zones) were renamed during the historical development process. In the world map of Köppen (1918) main climatic zones are called as following: (A) tropical rain climate, (B) dry climate, (C) warm temperate climate, (D) sub-arctic climate and (E) snow climate. In the map of Köppen (1931) the main climate (D) is called boreal climate. In Köppen and Geiger (1951) boreal climate was renamed to snow climate and climate (E) is called ice climate. As far as possible we applied the nomenclature after Köppen and Geiger (1951).
