Under normal conditions upwelling of cold CO2 - rich water from depth leads to outgassing when upwelled water warms at the surface.

Thus, it can be speculated that water carried to the surface by upwelling during positive dipole events is becoming colder and results in a colder EEIO during positive events in recent decades.

Rather non-native oyster larvae died in factory larvae farms along the coast when they mistakenly used cold, upwelled water during a few summer periods.

Now, you have less upwelling cold water to heat up, and you get more warming — as in El Nino (a la 1998).

Other nutrients are from upwelling where winds blow water away from a coast and the water is replaced by denser, cold nutrient laden water from below.

When upwelling brings cold water to the ocean's surface, cooling the atmosphere, where is that heat lost from the atmosphere «hiding»?

Science 275: 957 - 960) have suggested that the upwelling of cold water in the Eastern Pacific provides a kind of thermostat which keeps the Eastern waters from warming as much as the Western warm pool waters.

Eventually, the cold bottom waters returm to the surface through mixing and wind - driven upwelling, continuing the conveyor belt that encircles the globe.

Pete Best, If you have more cold water upwelling than normal, that is that much more heat going into the ocean just to maintain the surface temperature.

It's always worth remembering that the other end of the AMOC involves two main factors: (1) vorticity - mixing of heat from surface waters into the deep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Current.

Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions of the Equitorial Pacific and the Indian Ocean, strongly cooler in the nearest deep convection source region of the South Atlantic near Africa and the Equator, warm over the bulk of the North Atlantic, strongly warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased transport of cold water from the north whenever the Gulf Stream is running quickly.

Marine biological activity then transfers a bit more C to the deep ocean than cold, upwelling waters bring back up, such that the net sink to the deep ocean is about 1.6 GtC / yr, and much slower permanent removal in sediments.

Now, there is a more viable thermostat in the work of Amy Clement, who shows that cold water upwelling can provide a kind of thermostat.

In normal years, spring and summer winds lead to upwelling of cold, nutrient - rich waters at the coast, fueling the highly productive California Current ecosystem.

Furthermore, during the peak of the upwelling season (May - June), central and northern California Current coastal waters returned to normal temperatures as cold water was brought to the surface.

Now the researchers noticed that all of these flu pandemics started in the boreal spring or summer and were preceded by La Niñas — the phases in the El Niño Southern Oscillation (ENSO) that see large upwelling of cold deep ocean water in the East Pacific, which is then spread out across much of the ocean.

Between 2 and 3 million years ago the cooling of the deep oceans reached a tipping point, and modern upwelling regions ogf cold deep water off the coast of Peru, California and the west coast of Africa were established.

«So what happens after an El Nino suppresses the cold upwelling, all that cold water that was sitting down there, which normally would have been dispersed into the tropical Pacific, comes up and so the temperature drops pretty substantially after a major El Nino.

The cold, upwelling water propagates across the Pacific in a series of ocean and atmospheric feedbacks.

Beyond that I predict nothing — but the decline in solar activity widely anticipated suggests the likelihood of more cold water upwelling in the eastern Pacific this century.
