The Southern Oscillation Index (SOI) is indirectly based on temperature.

Reliable data on decadal variability of the Earth's radiation budget are hard to come by, but to provide some reality check I based my setting of the scaling factor between radiative forcing and the SOI / PDOI index on the tropical data of Wielecki et al 2002 (as corrected in response to Trenberth's criticism here.)

Based on this estimate and on the typical magnitude of Spencer's combined SOI / PDOI index, I chose a scaling factor (Roy's a) of 0.27 W / m2..

He took two indices of interannual variability: the Southern Oscillation (SOI) index, which is a proxy for El Nino, and the Pacific Decadal Oscillation Index (Pindex, which is a proxy for El Nino, and the Pacific Decadal Oscillation Index (PIndex (PDOI).

The analyses from SOI, Nino 3 index and GCM's are all comparable.»

A combination of vertical and horizontal excitation in forcing could certainly lead to the quasiperiodicity seen in the ENSO indices such as SOI.

A classic example is the Southern Oscillation (SO), encompassing the entire tropical Pacific, yet encapsulated by a simple SO Index (SOI), based on differences between Tahiti (eastern Pacific) and Darwin (western Pacific) MSLP anomalies.

It finds that the Southern Oscillation Index (SOI)-- the basic tool for forecasting variations in global and oceanic patterns — and rainfall fluctuations recorded over the last decade are similar to those in 1914 -1924.

The Southern Oscillation Index (SOI) is a metric for describing warm - and cold - phase conditions associated with the El Niño — Southern Oscillation (ENSO) and can also describe movements of the position of the SPCZ.

The SOI (southern oscillation index) is also spiking up again this month, which argues against the bottoming out of the current La Nina.

Rather than define a somewhat arbitrary threshold for a La Niña / El Niño year (i.e. based on the size of the index and number of months exceeding a certain threshold) or limiting the analysis to one ENSO index, I first took the average of the three indices mentioned above (ONI, MEI, and SOI, accounting for the fact that positive SOI indicates La Niña conditions while the opposite is true for ONI and MEI).

And what about the other indices that are indicative of changes in the El Niño Southern Oscilation (ENSO), like the Multivariate ENSO Index (MEI) and Southern Oscillation Index (SOI)?
