Define the Koppen climate classification and give one short worked example.

# Köppen Climate Classification The **Köppen climate classification** is a widely-used system that categorizes Earth's climates based on **temperature** and **precipitation patterns**. Developed by Wladimir Köppen in 1884 (and refined later), it uses letters to denote climate types: ## Main Climate Groups: - **A** - Tropical (hot year-round) - **B** - Dry (evaporation exceeds precipitation) - **C** - Temperate (mild winters) - **D** - Continental (cold winters) - **E** - Polar (extremely cold) Additional letters specify precipitation patterns and temperature details. ## Worked Example: London, UK **Data:** - Coldest month (January): 5°C average - Warmest month (July): 18°C average - Precipitation: Rain year-round, ~600mm annually, driest month still has 40mm **Classification Process:** 1. **First letter:** Coldest month >0°C and warmest >10°C → **C** (Temperate) 2. **Second letter:** No dry season, rain all year → **f** (fully humid) 3. **Third letter:** Warmest month <22°C, at least 4 months >10°C → **b** (warm summer) **Result: Cfb** - Temperate oceanic climate (or Marine West Coast climate) This matches London's mild, rainy weather perfectly!
