1. Oceanic Influences on Climate

2. Ocean currents redistribute heat
Large scale currents are called gyres

5. North Atlantic Gyre
Includes the Gulf Stream

6. SST in Gulf Stream- July

7. Influence of Gulf stream SST on air temp

8. Walker cell circulation

9. El Nino and La Nina years since 1950.
El Nino years produce weird weather in North America
La Nina years are more “normal”

10. Prevailing windflow along the ITCZ pushes warm water eastward
Position of ITCZ shifts North with Northern Hemisphere summer and south with the Southern Hemisphere summer

11. SST July- Illustrating El Nino Southern Oscillation (ENSO)

12. SST- Equatorial Pacific July

13. SST January- El Nino Southern Oscillation
