1
Improvements to SAR models
Dr Øyvind Breivik Norwegian Meteorological Institute
2
Improved wind and currents
Winds Higher resolution – 4 km near rugged coastlines and in fjords, bays and estuaries to resolve topographic effects Currents Higher resolution – 1 km for fjords, bays and estuaries HF currents and the STPS
3
300 m resolution ocean model
4
Errors and uncertainties
Assessing the relative importance of uncertainties in wind, currents and drift properties Ensemble winds (ECMWF 51) Random flight – autocorrelated wind and current perturbations
5
Alternative strategies
Currents switched off for very high resolution simulations? Inverse leeway for backtracking from debris
6
Improved taxonomy Redo older leeway categories with new field methods
Refine the taxonomy for different parts of the world – in close collaboration with RCCs
7
ECMWF 51
