| Zusammenfassung |
| This study presents the upgrade of the Optimal Interpolation scheme used in
the basin scale assimilation scheme of the Mediterranean Forecasting System.
The modifications include a daily analysis cycle, the assimilation of ARGO
float profiles, the implementation of the geostrophic balance in the
background error covariance matrix and the initialisation of the analyses. A
series of numerical experiments showed that each modification had a positive
impact on the accuracy of the analyses: The daily cycle improved the
representation of the processes with the temporal variability shorter than a
week, the assimilation of ARGO floats profiles significantly improved the
salinity analyses quality, the geostrophically balanced background error
covariances improved the accuracy of the surface elevation analyses, and the
initialisation removed the barotropic adjustment in the forecast first time
steps starting from the analysis. |
