| Zusammenfassung |
| A comparison of the Naval Research Lab Layered Ocean Model (NLOM)
nowcast fields with independent in-situ observations from a cruise
in the Polar Frontal Zone of the Atlantic Sector of the Southern
Ocean is presented.
NLOM sea surface temperature fields can be used to determine the
position of fronts and individual eddies, whereas the analyzed sea
surface height appears to be out of phase. It is suggested that this
dynamical inconsistency is caused by a low data coverage for
assimilation at the time of the cruise in combination with the data
assimilation technique, that treats sea surface height and sea
surface temperature data independently. |
