Earth and Life

Draw in and label the following GCM features. Double check your arrows and make sure they are pointing the right direction. Directions matter in Earth Science.

1. Polar highs

2. Westerlies

3. Trade winds

4. Equatorial low

5. Hadley Cell (with arrows)

6. Subtropical highs

7. Intertropical Convergence Zone (ITCZ)

8. Subpolar Lows

9. Polar Easterlies

10. Jet stream

Draw in the five ocean gyres. Make sure the arrows make sense. Label the warm and cold currents as ‘W’ and ‘C’ respectively on the appropriate sides (east and west) of the gyres. Do not label north / south as cold / warm. We know the poles are cold and the equator is warm.

This second diagram is just for practice if you need it:
