 Through this code collaboration, HIRLAM consortia developed the new generation cloud-resolving NWP system Harmonie-arome, which focus on operational application of kilometer scale, ensemble foeecast with focus to predict and warn high impact weather such as flashflood, thunderstorms, heavy rain in summer and gusty wind, snow storms etc in winter.At DMI, Harmonie-based kilometer-scale forecast system has been gradually operationalised since 2013 for use in routine forecast for Greenland, Faroe Islands and Denmark.In 2017, DMI introduced an innovative 25-member 2.5 km resolution ensemble forecast system COMEPS (COntinuous Mesoscale Ensemble Prediction System), which is based on hourly data assimilation on overlapped observation window, and an hourly refresh of probabilistic forecast with lagging.
