Climatic classification is an attempt to arrange the complex and continuous variations of climate into systematic categories so that similarities and differences among regions can be clearly understood. One important approach is the empirical or descriptive approach, which classifies climates on the basis of observed weather elements such as temperature, rainfall, humidity, and seasonality. These classifications rely on long-term averages and are closely linked with natural vegetation and human experience. The Köppen classification is the most prominent example of this approach. Another approach is the genetic or causal approach, which focuses on the processes and causes of climate rather than just outcomes. It considers factors such as air masses, fronts, pressure systems, and global circulation patterns. The Bergeron and Strahler classifications are examples where the origin and movement of air masses play a central role. A third approach is the applied or functional approach, which classifies climate according to its relevance to specific human activities such as agriculture, water resources, or health. Thornthwaite’s climatic classification, which emphasizes water balance and evapotranspiration, represents this approach. Modern approaches also include dynamic and quantitative classifications using statistical techniques, satellite data, and climate models to capture variability and change over time. Among all systems, the Köppen climatic classification remains the most widely used
