Subharmonic resonance of global climate to solar forcing

TL;DR

This paper demonstrates that global temperature fluctuations from 1880 to 2009 are primarily driven by a one-third subharmonic resonance to annual solar forcing, highlighting oceanic Rossby waves and their influence on phenomena like El Nino.

Contribution

It reveals the dominance of one-third subharmonic resonance in global temperature variability and discusses the role of Rossby waves and resonance in climate phenomena.

Findings

Global temperature fluctuations are dominated by one-third subharmonic resonance.

Oceanic Rossby waves significantly influence climate variability.

Resonance contributes to understanding El Nino dynamics.

Abstract

It is shown that, the wavelet regression detrended fluctuations of the monthly global temperature data (land and ocean combined) for the period 1880-2009yy, are completely dominated by one-third subharmonic resonance to annual forcing (both natural and anthropogenically induced). Role of the oceanic Rossby waves and the resonance contribution to the El Nino phenomenon have been discussed in detail.
