OpenIFS experiment data for "How do stratospheric perturbations influence North American weather regime predictions?"

<p>Primary processed experiment data output from 20 OpenIFS experiments used in &quot;<em>How do stratospheric perturbations influence North American weather regime predictions?</em>&quot; (Lee et al., submitted to J. Climate).</p> <p>Date in file string corresponds to initialisation date.</p> <p>Each netCDF file contains:</p> <ul> <li>Valid time</li> <li>500 hPa geopotential heights and anomalies for both control run &amp; polar stratosphere relaxed runs</li> <li>North American principal component loadings for control &amp; relaxed runs</li> <li>Daily North American regime attribution for control &amp; relaxed ensembles, and regime of ensemble mean (0 = ArH, 1 = ArL, 2 = AkR, 3 = PT)</li> <li>100 hPa 60N zonal-mean zonal winds in control &amp; relaxed ensembles</li> </ul> <p>Ensembles contain 21 members, where member 0 is the unperturbed member.<br> <br> &nbsp;</p>
