1. Climate Regions

2. Scientists Classify Climate According to Two Major Factors Temperature Precipitation

3. Köppen (KEP un) System Included distinct vegetation in different areas. Identifies broad climate regions ◦ Each has smaller subdivisions

4. Six Main Climate Regions Tropical Rainy Dry Temperate Marine Temperate Continental Polar Highlands

5. Tropical Rainy Subdivisions Tropical Wet – Always hot and humid; Heavy rainfall; 6 Centimeters per month all year long.

6. Tropical Wet Rainforest

7. Tropical Rainy Subdivisions Tropical Wet - and - Dry – Always hot; Alternating wet and dry seasons; Heavy rainfall in the wet season.

8. Tropical Wet - Dry Savanna – Grassland close to the equator; 120 centimeters of rain per year.

9. Dry Climate Subdivisions Arid – Arid Regions/Deserts; Less than 25 centimeters of rain; Hot and Sandy, Cold or Rocky.

10. Dry Climate Subdivisions Semi-Arid – Dry; 25-50 centimeters of precipitation per year.

11. Semi-arid Steppe – prairie or grassland

12. Temperate Marine Climate Subdivisions Marine West Coast – Mild winters; Cool summers; Moderate precipitation all year.

13. Temperate Marine Climate Subdivisions Mediterranean – Warm; Dry summers; Rainy winters.

14. Temperate Marine Climate Subdivisions Humid Subtropical – Hot summers; Cool winters

15. Temperate Continental Climate Subdivisions Humid Continental – Hot, humid summers; Cold winters; moderate precipitation all year.

16. Temperate Continental Climate Subdivisions Subarctic – Short, cool summers; Long, cold winters; Light precipitation mainly in summer.

17. Polar Climate Subdivisions Icecap – Always below freezing ( At or below 0º Celsius).

18. Polar Climate Subdivisions Tundra – Always cold; Short, cool summers; Bitterly cold winters.

19. In The Tundra Permafrost – Permanently frozen soil; cannot drain… wet and boggy in summer.

20. Highlands Highlands – Cooler and wetter than nearby lowlands. (Temperature decreases with altitude)
