The correct match between List-I (Koppen’s Climatic Type) and List-II (Letter Code) is A-1, B-4, C-2, D-3.
– Koppen’s climate classification uses letter codes to represent different climate types based primarily on temperature and precipitation characteristics.
– A. Tropical wet climate is characterized by consistently high temperatures and heavy rainfall throughout the year, designated by the code Af (A: Tropical, f: fully humid).
– B. Mid-latitude desert is an arid climate type found in mid-latitudes, often experiencing cold winters. The code BWk represents Arid (B), Desert (W), and Cold (k).
– C. Mediterranean climate is characterized by hot, dry summers and mild, wet winters. The code is Cs (C: Temperate, s: dry summer).
– D. Humid continental climate is found in mid-latitudes of continents, characterized by large seasonal temperature variations with warm to hot summers and cold winters, and precipitation throughout the year. The code is Df (D: Continental, f: fully humid).
– Matching the types to codes gives: A-1 (Af), B-4 (BWk), C-2 (Cs), D-3 (Df).
– The first letter of the Koppen code usually indicates the main climate group (A: Tropical, B: Arid, C: Temperate, D: Continental, E: Polar).
– Subsequent letters denote precipitation patterns (f: fully humid, w: dry winter, s: dry summer, m: monsoon) and temperature characteristics (a: hot summer, b: warm summer, c: cool summer, d: extremely cold winter, h: hot arid, k: cold arid).
