NEMO and LIM2 forecast changes in the sea-surface temperature (SST) and sea ice evolution.  These are used interactively by all IFS atmospheric models.  Medium range ENS and extended range ENS use the same initial ice extent.

Note: ECMWF uses LIM2 which is an earlier version of the Louvain-la-Neuve sea ice model that is currently available (Version 3.6)

• Movement of ice (turquoise) in the northern Gulf of Bothnia  due to the winds.
• Steady rise of sea-surface temperatures in the Black Sea, and especially in the shallow waters of both the Sea of Azov and the northern Caspian Sea.  In the White Sea (east of Finland, top of plot) sea-ice cover is less than the climatological average for this time of year.  Using these plots, the user can assess where sea-ice cover is above/below average.

The impacts of differently-evolving SST distributions of sea surface temperature and ice cover distributions should be considered when comparing different forecasts, even when they are from the same data time.
