Köppen climate classification
The major climatic types are based on patterns of average precipitation, average temperature, and natural vegetation. This map depicts the world distribution of climate types based on the classification originally invented by Wladimir Köppen in 1900.
In the Köppen climate classification system, Type D climates are defined by specific temperature thresholds regarding their warmest and coldest months:
- Warmest month: The average temperature must be 10 °C or higher.
- Coldest month: The average temperature must be –3 °C or lower.
Additionally, a specific subtype designation, "d," is applied if the temperature of the coldest month is less than –38 °C.1
