Water properties and circulation in Arctic Ocean models
As a part of the Arctic Ocean Model Intercomparison Project, results from 10 Arcticocean/ice models are intercompared over the period 1970 through 1999. Models monthlymean outputs are laterally integrated over two subdomains (Amerasian and Eurasianbasins), then examined as functions of depth and tim...

As a part of the Arctic Ocean Model Intercomparison Project, results from 10 Arcticocean/ice models are intercompared over the period 1970 through 1999.

Differences in such fields asaveraged temperature and salinity arise from models differences in parameterizationsand numerical methods and from different domain sizes, with anomalies that develop atlower latitudes carried into the Arctic. A systematic deficiency is seen as AOMIP modelstend to produce thermally stratified upper layers rather than the cold halocline,suggesting missing physics perhaps related to vertical mixing or to shelf-basin exchanges.Flow fields pose a challenge for intercomparison.
