While scientists are still working to determine precisely what confluence of conditions allowed for the Triple R's extraordinary multi-year persistence — and which may include effects from regions as far away as the Arctic — there is considerable evidence that a fundamental driver of the Triple R's longevity was the persistent warmth of the western tropical Pacific ocean (mentioned in the first section of this article).

For many parts of the Americas and Asia, the occasional warming and cooling cycles in the tropical Pacific Ocean known as El Nino and La Nina are unwelcome visitors — barging in, usually with little warning, then staying for months or sometimes a year or two, bringing all kinds of baggage in the form of distorted patterns of storms and droughts, heat and cold.

The most significant correlations occur in the Pacific Northwest with a lag time of 4 years, which is approximately equal to the travel time of water within the Pacific Gyre from the western tropical Pacific Ocean to the Gulf of Alaska.

Other natural events, like El Ninos, when warm water spreads over much of the tropical Pacific Ocean, also have large short - term influences on climate.

The most commonly accepted definition of an El Niño is a persistent warming of the so - called «Niño3.4» region of the tropical Pacific Ocean south of Hawaii, lasting for at least five consecutive three - month «seasons.»

Given that, «Climate simulations suggest that multi-decadal periods of high and low variability in the phenomenon known as the El Niño - Southern Oscillation in the tropical Pacific Ocean may be entirely unpredictable» DiNezio, 1014, we can not have confidence in any of our current ENSO forecasts

Reconstruction of Monthly SST in the Tropical Pacific Ocean during 1868 — 1993Using Adaptive Climate Basis Functions

In any year, temperatures around the world can be nudged up or down by short - term factors like volcanic eruptions or El Ninos, when warm water spreads over much of the tropical Pacific Ocean.

It has also entered the public consciousness because this climatic phenomenon in the tropical Pacific Ocean has worldwide effects.

An improved dynamical understanding of how the tropical Pacific Ocean transitions into hiatus events, including its seasonal structure, may help to improve future prediction of decadal climate variations.

It has been noted in a five - member multi-model ensemble analysis that, associated with the changes in temperature of the upper ocean in Figure 10.7, the tropical Pacific Ocean heat transport remains nearly constant with increasing greenhouse gases due to the compensation of the subtropical cells and the horizontal gyre variations, even as the subtropical cells change in response to changes in the trade winds (Hazeleger, 2005).

And the 1998/99/00 / 01 La Nina recharged the tropical Pacific Ocean Heat Content after the 1997/98 El Nino, returning it to the new higher level established by the La Nina of 1995/96.

It's based on the Tropical Pacific Ocean Heat Content and NINO3.4 SST anomaly data illustrated in Figure 3.

The La Nina event of 1998/99/00 / 01 recharged the heat content released by the 1997/98 El Nino and returned the tropical Pacific Ocean Heat Content to the new higher levels established during the 1995/96 La Nina.

Tropical Pacific Ocean Heat content is one component of global ocean heat content.

CLOSING COMMENT The La Nina event of 1973/74/75 / 76 provided the tropical Pacific Ocean Heat Content necessary for the increase in strength and frequency of El Nino events from 1976 to 1995.

«At the time of this writing (May 2010) the tropical Pacific Ocean has changed from El Nino conditions to ENSO - neutral and is likely headed into the cool La Nina phase of the Southern Oscillation.

Figure 3 is a graph of Tropical Pacific Ocean Heat Content compared to scaled NINO3.4 SST anomalies.

So there was a short - term recharge of tropical Pacific Ocean Heat Content in 1995/96, which is very evident in Figure 3.

Our comparison of tree ring - based drought analysis and records from the tropical Pacific Ocean suggests that changing variability in El Niño Southern Oscillation (ENSO) explains much of the contrasting variances between the MCA and LIA conditions across the American Southwest.

Our study stresses the importance of those internal connections between tropical Pacific Ocean SSTs, the ENSO system, and the American Southwest hydroclimatic conditions and supports the contention that: (1) internal variability of the ocean - atmosphere system may not be accurately represented in current global climate models, and (2) enhanced variability as a result of these stochastic events should be further considered.

These changes in tropical Pacific Ocean SSTs over the past millennium have often been associated with internal variability of the ocean - atmosphere system [19,27,53,54] that may not be accurately represented in current climate models.

The large interannual to decadal hydroclimatic variability in winter precipitation is highly influenced by sea surface temperature (SST) anomalies in the tropical Pacific Ocean and associated changes in large - scale atmospheric circulation patterns [16].
