In the West Pacific, the warm surface waters reach deeper than anywhere else in the ocean.

Stronger trade winds push warm surface water towards the west, and bring cold deeper waters to the surface to replace them.

A further point where I need clarification is that, in Part I, you seemed to be suggesting that the West Pacific warm pool develops due to the trade winds blowing surface water in that direction.

In the description of the El Niño, I noted that huge amounts of warm water from the surface and below the surface of the West Pacific Warm Pool had sloshed east during an El Nwarm water from the surface and below the surface of the West Pacific Warm Pool had sloshed east during an El NWarm Pool had sloshed east during an El Niño.

Sea level on the West coast may begin to rise due to climate regime shift as warm surface waters return to the Pacific Read More

Now as soon as water is warmed — surface warm - water instantly goes east, no time to produce big moisture west.

All the sea surface water, warmed by the tropical sun, is blown to the west of the Pacific and, to compensate part of the imbalance, cooler deep ocean waters well up on the western shores of Latin America (and spread all the way up to the Solomon Islands).

During El Niño, warmer than average surface waters and higher than normal sea levels persist along the U.S. West Coast.

A self sustaining upwelling in the central Pacific with twin Walker Cells pushing warm surface water both east and west.

Desler, Alexander, and Timlin (1996) said: «A prominent decade - long perturbation in climate occurred during the time period [1970 — 1991] in which surface waters cooled by 1 °C in the central and western North Pacific and warmed by about the same amount along the west coast of North America from late 1976 to 1988.»

El Ni o an irregular variation of ocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fishing

[TD] La Nina: Trade winds push warm surface water to the west, which causes deeper, colder water to rise to replace it.

It can not account for the huge volume of leftover warm water that's below the surface and returned to the West Pacific and into the eastern tropical Indian Ocean via off - equatorial slow - moving Rossby waves.

When there is a relaxation of trade winds, the warm water in the West Pacific Warm Pool sloshes to the east and speads across the surface and there's an El Nino event, which is the discharge mwarm water in the West Pacific Warm Pool sloshes to the east and speads across the surface and there's an El Nino event, which is the discharge mWarm Pool sloshes to the east and speads across the surface and there's an El Nino event, which is the discharge mode.

Much of it is forced down and it flows back to the east at 200 metres depth and when the warm water surfaces at the Galapogos Islands in 9 months (replaceing the water which is flowing east - west at the surface), it starts to slow down the Trade Winds because of the convection effect.

The West Antarctic Peninsula is bathed by relatively warm waters from the Antarctic Circumpolar Current that comes close to the surface near the peninsula, and that current is gaining heat as the oceans warm, studies show.

The best way to envision the relation between ENSO and precipitation over East Africa is to regard the Indian Ocean as a mirror of the Pacific Ocean sea surface temperature anomalies [much like the Western Hemisphere Warm Pool creates such a SST mirror with the Atlantic Ocean too]: during a La Niña episode, waters in the eastern Pacific are relatively cool as strong trade winds blow the tropically Sun - warmed waters far towards the west.

When the intensity of ultraviolet light from the sun increases, temperature rises in this ozone rich air and weakens the downdraft, lowers the surface pressure and with it the strength of the trade winds that blow across the ocean to the low pressure zones that form over the warm waters that accumulate in the west.

The layer of warm surface water that was blown west is then replaced by cooler water from the subsurface, cooling the entire tropical Pacific.

And part of it caused by the warm surface waters being blown back to the west when the trade winds resume after the El Niño.

Warm surface and subsurface waters in the west Pacific warm pool provide the fuel for El Niños, so, as you noted, there has to be warm water for an El Niño to fWarm surface and subsurface waters in the west Pacific warm pool provide the fuel for El Niños, so, as you noted, there has to be warm water for an El Niño to fwarm pool provide the fuel for El Niños, so, as you noted, there has to be warm water for an El Niño to fwarm water for an El Niño to form.

Soon the eastern trade winds start pushing the warm tropical surface waters and their associated thunderstorms and clouds to the west across the Pacific and eventually poleward again.

Warm water ceases to surge into the eastern Pacific from the west (it was «piled» by past easterly winds) since there is no longer a surface wind to push it into the area of the west pacific.

The fall, revealed by Nasa satellite measurements of the lower atmosphere, has been caused by the end of El Nino — the warming of surface waters in a vast area of the Pacific west of Central America.

For example, I think that the PDO spreads colder upwelling East Pacific water westwards over a greater fraction of the Pacific, and therefore leaves less surface room for the warmer water that deepens as a warm pool in the West Pacific.

An El Niño event releases that La Niña - created warm water from below the surface of the west Pacific Warm Pool, and an El Niño spreads that warm water eastward across the eastern tropical Paciwarm water from below the surface of the west Pacific Warm Pool, and an El Niño spreads that warm water eastward across the eastern tropical PaciWarm Pool, and an El Niño spreads that warm water eastward across the eastern tropical Paciwarm water eastward across the eastern tropical Pacific.
