Verification of what?

This is what I find most poor about most verifications: stuff like 500mb root mean square error is hardly of use to the person on the ground who might want to try and understand which forecasting model is best.

Would be great to see how well Lamb weather types or Grosswetterlagen can be forecasted in advance in different models - e.g. Scandinavian block is forecast on average 5.5 days ahead by ECMWF but only 4.5 days ahead by the GFS. This would, I guess, require a human input - but something I notice that Bruce Messer tried his hand at on his blog a few months ago.

It would also be interesting to contrast the raw model T+0 output with the observations assimilated into the model to compare these differences...
