ECMWF HRES Accuracy for Temperature and Precipitation

1 / 5

ECMWF HRES temperature RMSE rises with lead time and is highest over complex terrain such as the Alps and Scandinavia.

2 / 5

Precipitation fractions skill score at 50 km scale declines with lead time and drops further for summer convection beyond day 5.

3 / 5

EPT-2 beats HRES on 2 m temperature RMSE at every lead time from 0–240 h when verified against more than 10,000 European stations.

4 / 5

Update frequency and ensemble depth shape trading value: EPT-2 refreshes up to 24× daily and EPT-2e, the ensemble variant, outperforms the 50-member ECMWF ENS mean on both RMSE and CRPS at virtually all horizons.

5 / 5
