On March 11, ECWMF introduced a modified version of their model system; their websites<br>mentions<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">
The main changes in this revision are:<ul><li> Use of persisted SST anomalies in all atmospheric forecasts</li><li>Daily ocean-coupling of days 10 to 15 of 0000 UTC EPS forecasts</li><li>Monthly Forecast run once per week from 0000 UTC on a Thursday as an extension of the 15 day EPS forecast from this base time </li>
<li>Modified EFI products using the new unified re-forecasts</li><li>New GRIB description for all Monthly Forecast products, analogous to the current medium-range EPS data</li></ul></blockquote>
<p>Maybe you stumbled across the last point? I do not know the details of the changes, though... and I don't know the details. Oh, they also say</p><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">
The new GRIB model identifiers are: 131 (atmospheric model). Model
numbers for the Global wave model will remain at 116. Also for the
European waters wave model the number will remain 216.<br></blockquote><br>I don't know - would the change of the model identifier require a new grib table in wgrib? Anyway, at least you now know that something did change on the ECMWF side...<br>
