| Research Abstract |
We carried out 63-member coupled ocean-sea-ice simulations forced by outputs from atmospheric ensemble reanalysis, and found that seasonal variations of the ensemble spreads are quite different between sea-ice concentration and thickness. We also developed an atmospheric data assimilation system using a global coupled atmos-phere-ocean-sea-ice model, and howed some signatures of atmosphere-ocean interaction via sea ice in the analysis fields.
