From: John Daly <daly@vision.net.au> To: n.nicholls@BoM.Gov.Au Subject: Re: Climatic warming in Tasmania Date: Fri, 09 Aug 1996 20:04:00 +1100 Cc: Ed Cook <drdendro@ldgo.columbia.edu>, NNU-NB@palais.natmus.min.dk, k.briffa@uea.ac.uk, Mike Barbetti <mikeb@emu.su.oz.au>, zetterberg@joyl.joensuu.fi, rjf@dar.csiro.au Dear Neville, You mentioned to me some time ago that in your view, the 11-year solar cycle did not influence temperature. There have been numerous attempts by academics to establish a correlation, but each has been shot down on some ground or other. I remember Barrie Pittock was especially dismissive of attempts to correlate solar cycle with temperature. Have you tried this approach? Load "Mathematica" into your PC and run the following set of instructions - data = ReadList[ "c:\sydney.txt", Number] dataElements = Length[data] X = ListPlot[ data, PlotJoined-> True]; fourierTrans = Fourier[data]; ListPlot[Abs[fourierTrans], PlotJoined -> True]; fitfun1 = Fit[data,{1,x,x^2,x^3,Sin[11 2 Pi x/dataElements],
