Zusammenfassung |
A model intercomparison between two atmospheric models, the
non–hydrostatic Lokal Modell (LM) and the hydrostatic HIgh Resolution
Limited Area Model (HIRLAM) is carried out for a one-week period,
including a case of cyclogeneis leading to heavy precipitation over
Northern Italy.
The two models, very different in terms of data-assimilation and numerics,
provide different results in terms of forecasts of surface fields.
Opposite diurnal biases for the two models are found in terms of screen
level temperatures.
HIRLAM wind speed forecasts are too strong, while LM precipitation forecasts
have larger extremes.
The intercomparison exercise identifies some systematic differences in the
weather products generated by the two systems and sheds some light on the
biases of the two numerical weather prediction systems. |
