The paper has just been published in Nature Geoscience and I thought that it might be a good idea to email it around as I'm not sure homw institutions are signed up for the new Nature Geoscience journal.

Murphy; Abram, Nerilie Subject: Fwd: GRL paper of lecture given at the 2008 Moorea Conference Dear Colleague, Zhengyu Liu and I just had our "solar- ENSO" paper published in GRL this month. It shows that the 11-year period solar radiative forcing during the 20th Century not only drove the 11-year period QDO signal in tropical Pacific sea surface temperature variability, but the 3.6- year period ENSO signal and the 2.2-yr period QBO signal as well, the latter two signals driven by non-linear processes, together accounting for 51% of the variance in the Nino-3 SST index from 1900-2005. We owe this paper to Joanna Haigh, who spurring us on after she sent me an e-mail questioning the recent work of Jerry Meehl and Harry van Loon. This paper explains an apparent discrepancy; that is, why El Nino and La Nina are both phase locked to the 11-year period solar cycle as Jerry and Harry observed. In this paper, the the 3.6- year period ENSO signal and the 2.2-yr period QBO signal are the third and fifth odd harmonics of the first harmonic 11-yr period QDO response to 11-yr period solar forcing, each of these signals already shown to obey the same delayed action/recharge oscillator in tropical Pacific coupled ocean-atmosphere system.
