Comparison of latest MM5/WRF forecasts to 13km hourly RUC analysis

Notes:

Both grids are regridded to 0.1 degree resolution before comparison.

The MM5, WRF are initialized off GFS not RUC. Thus, differences from RUC should exist even at forecast hour 0.

Neither MM5 nor RUC offers 6 meter winds; both fields are extrapolated from their respective models' 10 meter winds. Thus, the 6 meter windspeed differences essentially duplicate (but with new magnitudes) the 10 meter windspeed differences.

WRF does not offer 6 meter or 10 meter winds; both fields are linearly extrapolated from the lowest model level assuming sfc wind = 0. RUC 6 meter winds are linearly extrapolated from RUC 10 meter winds assuming sfc wind = 0.
