Köppen-Geiger Global Climate Classification

The Köppen climate classification system divides terrestrial climates into five primary physiological zones based on vegetative thresholds, seasonal thermal variance, and precipitation periodicity.

Zone A: Tropical Humid

All months average temperature above 18°C. Characterized by high annual precipitation, absence of winter season, and lush tropical rainforest biome.

Zone B: Dry & Arid Deserts

Annual potential evapotranspiration significantly exceeds total precipitation. Diurnal temperature swings frequently exceed 25°C.

Zone C: Temperate & Maritime

Mild winters with coldest month between -3°C and 18°C. Distinct 4-season cycle, typical of Mediterranean, Western Europe, and coastal North America.

Zone D: Continental & Boreal

Warm summer and severe freezing winters with continuous seasonal snowpack. Common across Canada, Northern US, and Scandinavia.
