So now, we see that the oceans affect our climate on a seasonal basis with the onset of upwelling in the late spring and summer and its waning in the fall.  
Can you think how this affects climate along the coast of central and northern California?
The meeting of the cold air, formed over the cold, upwelling water,  with the warm summer air over the land produces coastal fog, which is so common in Monterey, Santa Cruz, Half Moon Bay and San Francisco during our summer.

The fog provides the San Francisco bay area with a "natural" air conditioner, which prevents a typical spell of hot weather from lasting more than a few  days (at least near the coast).  
If you have ever been to the Monterey Bay Aquarium, you learned about the effects that upwelling has on the marine ecosystem along central and northern California and how the waxing and waning of upwelling causes a change in the migration patterns of marine organisms into the bay, thereby transforming the ecosystem.

How does upwelling influence the formation of fog along the coast in the bay area?

Learn about advection fog and its relationship to upwelling and the coastal ecology.
