Implementation of the Newest Sea-Ice Model (CICE 6.0) for Baltic Sea Area

Implementation of the newest sea-ice model (CICE 6.0) for Baltic Sea area Jaromir Jakacki, Maciej Muzyka, Marta Konik, Małgorzata Stramska Institute of Oceanlogy Polish Academy of Sciences Sopot, Poland BOOS Workshop on Integrated Baltic Sea Operational Oceanography Leibniz-Institut für Ostseeforschung Warnemünde (IOW), Rostock, Germany 2019 Outline: • Motivation • CICE v6 improvements • Model configuration • Results • Future plans Motivation: • Currently we have operational version of the coupled ocean-ice model, but this model has been published in 2008 (CICE v4) • Baltic Earth Working Group on the "Baltic Sea Model Intercomparison Project (BMIP)” – sea ice part of the project THIS WORK IS ONGOING CICE model improvements • There is not a lot of information about changes, they introduced ice pack column physics which currently part of the CICE model • Both parts – CICE and ice pack are treated separately • Fast ice is implemented in the keel form • Under development thus we assume • … but maybe it will not have old bugs such as ice creation in the land mask area – we will see Model configuration • Currently we are working on stand alone version • Atmospheric data from our operational WRF model • Bottom boundaries from eBalticGrid system (almost operational, validated and published) Buoy position: 18.67255, 54.356933 Results Results Divided in there scales: • global • regional • local Results Results Divided in there scales: • global • regional • local Results Results Divided in there scales: • global • regional • number local Box Box Comparison with satelite data from marine.copernicus.org – combined (global and regional) and not combined (local) All of the results are for the winter 2017-2018 Baltic Sea ice cover (total area) mean ice thickness Sea ice thickness distribution Copernicus from data analyzed and Modelled Selected regions of the Baltic Sea area Gulf of Finland mean ice thickness Sea ice thickness distribution Copernicus from data analyzed and Modelled Selected regions of the Baltic Sea area Bay of Bothnia mean ice thickness Sea ice thickness distribution Copernicus from data analyzed and Modelled Selected regions of the Baltic Sea area Bothnia Sea mean ice thickness Sea ice thickness distribution Copernicus from data analyzed and Modelled Local scale comparison -
