Regional Climate Model Ouput: 1979-1988

Climatologies from two simulations by regional climate models (HIRHAM and RegCM2) driven by the NCEP/NCAR reanalysis for the 10-year period 1979-1988. The observed climatology used for comparison covers the same period. The model domain is the same as used by the Project to Intercompare Regional Climate Simulations (PIRCS).

PLEASE NOTE:

Results linked to this page are preliminary. They should not be discussed, cited or otherwise referenced without consulting DMI and ISU modelers who produced these results.

(1) Elevation

A common elevation grid at 1/2 degree has been produced from ((PLEASE FILL IN)) using a Cressman scheme for horizontal interpolation. Model and observing station elevations have also been interpolated to the 1/2 degree grid using the same Cressman scheme. These figures show differences between
- each model and the common grid elevations
- observing station elevations and the common grid elevations.
Contour interval: 250 m, from -1375 m.

(2) Daily maximum temperature

These maps show the 10-year climatology of daily maximum temperature [deg C] by month of the year. Each month has three panels: 

model climatology     model-obs bias     observed climatology
Months are grouped according to meteorological seasons (Dec-Jan-Feb, etc.) Contour interval: 5 deg C, from -17.5 deg C

(3) Daily minimum temperature

The same as (2), but for daily minimum temperature climatology.

(4) Precipitation

The same layout as (2), but for precipitation climatology. Observations from VEMAP gridded monthly precipitation dataset
Contour interval: 1 mm/day, from -5 mm/day

Also available here are NCEP reanalysis average precipitation for January and July.

(5) Surface fluxes

January and July surface flux climatology, model output only, in W/m**2.
