Data assimilation and prediciton of sea ice


Investigaing preditability of sea ice and climate variations in the pan arctic region by using climate models initialized with atmospheric and oceanic observational data including sea ice.

Model Characteristics

High resolution and good reproducibility of past climate variations

Computing Environment

Earth Simulator

Abstract (Brief description of the experiment contents (initial conditions, boundary conditions, etc.))
(1) This is one of CMIP6 participating climate model. The model exparienced long-term past and future climate simulations under the various CMIP6 protocols. In addition decadal climate predicion experiments were also conducted with the model initialized by using oceanic obsevations. (2) With this model, sea ice data asimilation by EnKF is now conducted to understand the role of sea ice in the climate systems over this planet..
