Hi,<br> <br><br> gfs.t12z.prgb2f12 is the 12 hour forecast started from 12Z. Clue is the f(forecast hour)<br><br> gfs.t12z.prgb2f00 is the 3 minute or so forecast started from 12Z. Unfortunately the<br> metadata doesn't mention it is a N minute forecast.<br>
<br> gfs.t12z.pgrb2anl is the analysis.<br><br> The f00 is the model state after a few time steps of the model integration. You<br>may see some transients as the model adjusts from the analysis state to something<br>
on the "slow manifold".<br><br> Wesley<br><br> <br><br><div class="gmail_quote">On Wed, Feb 8, 2012 at 11:06 AM, Jeff Lake <span dir="ltr"><<a href="mailto:admin@michiganwxsystem.com">admin@michiganwxsystem.com</a>></span> wrote:<br>
