Using Climatic Data to Identify Factors Influencing Climate

2. A. Comparing Annual Temperature Range as a Function of Latitude
The climographs for three locations, each at a different latitude, are shown below.

3. B. Coastal vs. Continental Temperature Ranges
Bismarck
New York LA
Phoenix

5. C. Marine Climates vs. Continental Climates
Both locations, A and B are at similar latitudes.
One location is Yakutsk, Russia and the other is Reykjavik, Iceland.

6. D. Prevailing Winds and Geographic Position
San Francisco has a marine climate due to the moderating effects of the Pacific Ocean.
St. Louis being far from a large body of water, has a much greater annual temperature range.
Norfolk at about the same latitude as San Francisco and St. Louis
Has a temperature range more like the continental climate of St. Louis than the marine climate of San Francisco.

7. E. The Effect of Mountains on Climate

9. The Orographic Effect

10. Great Distance From the Ocean
Most rainfall comes from evaporated ocean water
Dry climate in China north of 30o N
Interior location
Rainshadow of Himalayas

11. Rainfall Patterns on the Big Island of Hawaii
The map shows isolines called isohyets that connect points of equal rainfall

12. Compare the rainfall patterns to the topography of the Big Island.

13. Topography is the shape of the land.
Contour lines are isolines connecting points of equal elevation.
