Forecast skill

Is the blend better than every individual model? Matured forecasts are verified against gridded observations (ERA5 temperature and wind, GPM IMERG rainfall) by lead time, region, season and weather regime.

Which model is best when?

Rainfall RMSE (mm / 24 h) by lead time; best single model highlighted. The winner changes, which is why a fixed choice or a plain average is not enough.
