Assimilation of sea surface temperature, sea ice concentration and sea ice drift in a model of the Southern Ocean
Current ocean models have relatively large errors and biases in the Southern Ocean. The aim of this study is to provide a reanalysis from 1985 to 2006 assimilating sea surface temperature, sea ice concentration and sea ice drift. In the following it is also shown how surface winds in the Southern Oc...

Current ocean models have relatively large errors and biases in the Southern Ocean.

Such satellite observations are available since the late seventies and have the potential to improve the wind forcing before more direct measure- ments of winds over the ocean are available using scatterometry in the late nineties. The model results are compared to the assimilated data and to independent measurements (the World Ocean Database 2009 and the mean dynamic topography based on observations).

Finally a method to iden- tify model errors in the Antarctic sea ice area is proposed based on Model Output Statistics techniques using a series of potential predictors.
