<div dir="ltr">Remember that the largest wavenumbers on a regional domain are not the global wavenumbers. An easy way to avoid having to convert the regional wavenumbers to global ones is to use the global domain, but set everything outside the region of interest to zero. To avoid effects from the boundaries taper to zero instead of cutting off right at the edge of your domain.<div><br></div><div>Maria</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Aug 25, 2015 at 7:20 AM, Dennis Shea <span dir="ltr"><<a href="mailto:shea@ucar.edu" target="_blank">shea@ucar.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Not sure what "region" you are referring to.<br>

Say 'Pacific'<br>

At each latitude in the region take zonal anomalies and taper the<br>
regional boundaries to 0.0<br>
