WebThese charts show clustering of ENS members based on the 500 hPa height forecasts. These charts show the clustering of ENS members based on the 500 hPa geopotential forecast fields and is performed over four sub-section intervals of the 15-day forecast period. The clustering intervals are 72-96, 120-168, 192-240 and 264-360 hours). WebCluster product at ECMWF: large scale climatological regimes To put the daily clustering in the context of the large-scale flow and to allow the investigation of regime changes, the new ECMWF clustering contains a second component. Each cluster is attributed to one of a set of four pre-defined climatological regimes.
