Koeppen Scheme of Climate Classification
Koeppen Scheme of Climate Classification The most widely used classification of climate is the empirical system developed by V. Koeppen in 1918. Koeppen identified a close relationship between the distribution of vegetation and climate. He selected certain values of temperature and precipitation and related them to the distribution of vegetation, using these values for classifying climates. Koeppen recognized five major climatic groups. Four of them are based on temperature, while one is based on precipitation. A sixth group, Highland climates, is governed by topography. The major climatic groups are designated by capital letters: A, B, C, D, E, and H. 1. Group A: Tropical Humid Climates Tropical humid climates exist between the Tropic of Cancer and Tropic of Capricorn. The sun is overhead throughout the year, and the Intertropical Convergence Zone brings regular rainfall. The average temperature of the coldest month is 18 degrees Celsius or higher. This group is divided into thre...
