Climate Classification

2. Koeppen Classification System
Developed by Russian-born Germ climatologist Wladimir Koeppen
Based on monthly values of . . .
1) Temperature
2) Precipitation
Also distinguished natural vegetation
Designed a map to classify

3. Koeppen Classification System

4. Classification System
Tropical climate:
High temperatures
600 cm of rain
Along w/ mT air, formations of rain forests

5. Classification System
Dry climate:
30% of earth’s area, largest
cT air mass, desert areas
Low precipitation and vegetation
High evaporation

6. Classification System
Mild climates:
Generally on the coasts
Warm, muggy, high precipitation areas
Can receive west air from ocean
Warm winter and cool summers

7. Classification System
Continental climates:
Warm summer
Cool summer
Subarctic
Climate battleground: rapid, violent changes in weather

8. Classification System
Polar climates
Coldest regions on earth (warmest month <10oC)
Precipitation low: clouds hold less moisture
High elevations

9. Microclimates Localized area that differs from surrounding region
Heat Island
Concrete buildings create a warmer climate than rural areas
Large areas of asphalt and buildings
