<div dir="ltr"><div dir="ltr">Hi Melanie,<div>Typically what is done for PDO regressions is that you calculate the 1st EOF, then the associated principal component (PC) timeseries. You then regress other fields onto the PC timeseries. That way it is irrelevant if the original SST grid is different from the grid of the variable you are regressing. </div><div>For example:</div><div><div><br></div><div>evecv = eofunc(sst_CW({lat|20:70},{lon|110:260},time|:),2,75)</div><div>pcts = eofunc_ts(sst_CW({lat|20:70},{lon|110:260},time|:),evecv,False)</div><div>pctsS = dim_standardize(pcts(0,:),0)</div><div>delete([/pcts/])</div><div>finarr = regCoef(pctsS,sst2) ; returns global SST regressions</div></div><div>finarr_psl = regCoef(pctsS,psl) ; returns global PSL regressions</div><div><br></div><div>Adam</div><div><br></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 28, 2019 at 8:32 AM Melanie O' hanoly <<a href="mailto:mel.hanoly@gmail.com">mel.hanoly@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr">Hi Soma<div><br></div><div>I can not do this, because I just want to see the influence of the PDO (North Pacific) in the rest of the globe or I didnt understand what you mean<br></div><div><br></div><div>Thanks</div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 28, 2019 at 11:23 AM Soma Roy <<a href="mailto:somaroy892@gmail.com" target="_blank">somaroy892@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Use printVarSummary and print for lat and lon for both the variables and cut out only the common portion from the two..<div dir="auto"><br></div><div dir="auto">Hope this idea help you..</div><div dir="auto"><br></div><div dir="auto">Cheers,</div><div dir="auto">Soma</div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Mar 28, 2019, 19:48 Melanie O' hanoly <<a href="mailto:mel.hanoly@gmail.com" target="_blank">mel.hanoly@gmail.com</a> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr">Hi NCL Users<div><br></div><div>I'm trying to calculate the relationship between PDO and some variables of the globe, but I calculated the first EOF of north Pacific sst and then I'm trying regress analysis between salinity of global word but I got the error, because they dont have the same size, can anyone help me with this?
