Experience with AMPS and ECMWF

• during the season both models work very accurate
• AMPS has still an advantage in forecasts for
  surface winds
• EPS 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 AMPS
• humidity in AMPS (low stratus) is sometimes
  higher as observed
