Coordinated Modeling-Observational Approach for Change in the Arctic Seas
The sea ice cover in the Arctic Ocean has declined in the last 40 years and reaches the extreme condition, while its decadal variability has increased. The Polar Vortex has more significant decadal oscillations than the trend. The recently archived data extending from clouds, the atmospheric boundary layer to biogeochemical components in the Arctic Ocean show Arctic environmental change. The preliminary results include the following signal: the cloud cover has increased and is estimated to contribute to the ice reduction through the radiation balance. The biogeochemical data indicate ocean interior responses to the Arctic Oscillation. The sea level height in the Bering Sea shows an increasing trend and contributes to inflow of the Pacific Water into the Arctic Basin. Coupled ice-ocean models are used for simulating the signals in the Arctic seas, and in turn verified in comparison with the data. The models well duplicate the ice cover and ocean variability in the Arctic Ocean. The ice reduction in 1990s is suggested to occur as a consequence of a reduction in ridged ice and might recover in the next 10 years. Both modeling and observational approaches should be coordinated so that more reliable tools may be provided for predicting future change in the Arctic region. An attempt is made to couple the ice-ocean models with an atmospheric model to provide a basis for the trend and a future prediction.
