Experience with AMPS and ECMWFExperience with AMPS and ECMWF
during the season both models work very accurateAMPS has still an advantage in forecasts for surface windsEPS meteograms of ECMWF are used as the main technique for forecast up to 4 or 7 days the web access is a great advantage for AMPShumidity in AMPS (low stratus) is sometimes higher as observed
