KOPPEN'S CLASSIFICATION OF INDIAN CLIMATE
A Koppen’s classification is empirical in nature based on climatic data. Koppen, for the delineation of climatic regions took into consideration (i) the mean monthly temperature, (ii) the mean monthly rainfall, and (iii) the mean annual rainfall. Koppen divided the country into three broad climatic zones:
1. Humid (A)
2. Arid (B)
3. Semi-Arid (C and D)
These three broad climatic divisions were sub-divided into sub-types on the basis of seasonal variations in the distribution pattern of precipitation and temperature for which the symbols S, W, m, f, w, s, c, and h have been used. Based on Koppen’s climatic scheme, India can be divided into the following nine climatic regions (Fig. 4.22).
