Which Event Causes Upwelling?

Answer: Wind blowing parallel to the shore causes upwelling of cool water. Thermohaline circulation is mainly due to winds causing circulation of ocean water warmer, less dense water sinking in the ocean and cold water replacing it.

Is upwelling caused by density?

Upwelling. As you have seen, water that has greater density usually sinks to the bottom. ... Denser water from the deep ocean can come up to the surface in an upwelling (Figure 14.18). Generally, an upwelling occurs along the coast when wind blows water strongly away from the shore.

Does global warming cause upwelling?

It is hypothesized that global warming will enhance land–sea temperature gradients that in turn will increase upwelling favorable winds (i.e., the Bakun hypothesis)¹⁰.
