Generation

The Köppen climate classification is a widely used system that categorizes Earth's climates based on annual and monthly temperature and precipitation patterns, developed by climatologist Wladimir Köppen. It uses a letter code system where climates are divided into five main groups (A-tropical, B-dry, C-temperate, D-continental, E-polar) with additional letters indicating precipitation patterns and temperature characteristics. **Key formula**: For B (dry) climates, the threshold precipitation is calculated as: - **P_threshold = 2T** (if 70%+ precipitation in summer) - **P_threshold = 2T + 28** (if 70%+ precipitation in winter) - **P_threshold = 2T + 14** (otherwise) Where P is annual precipitation (cm) and T is mean annual temperature (°C); if P < P_threshold, the climate is classified as dry (B).
