<div>Hi Saeed,</div>
<div> </div>
<div>Thanks for the suggestion. My purpose is a bit differetnt, I would like to calculte correlation only for JJA season during whole years period (1979-2009). Say I have monthly data of CMAP dan SST, my imagine is that taking JJA season in each year (3 months x 30 years = 90 months). These 90 month sample size of JJA CMAP and SST will be correlated to each other.</div>
<div> </div>
<div>Do you have any idea?</div>
<div> </div>
<div>Thanks for advance.</div>

This function take a 45 days before and 45 days later(45+45=90=3month=1season) and a correlation in this period.<br><br>Regards<br><br>Saeed Bayat<br>M.Sc Student of Climatology<br>Ferdowsi University of Mashhad(Iran)<br>
