Numerical modeling of the arctic ocean deepwater formation: Part II. Results of regional and global experiments

摘要: In this study the specific features of deepwater generation in an area wind polynia and capability numerical models to transport bottom-density anomalies from shelf areas are considered. The results regional modeling indicate that displacement method presented first part leads a considerable supply dense deep waters at expense generated Barents Kara seas. With help given parametrization, these shown be able numerically significant distances where they edge oceanic with slightly changed initial density characteristics. This technique was tested within large-scale combined ocean-ice model for Arctic Ocean North Atlantic. method, have less clearly expressed trend decreasing total amount waters. However, does not eliminate problem adequately reproducing bottom model. Based on analysis results, we found longer period atmospheric influence prevalent cyclonic circulation decreased Ocean, while anticyclonic-type its recovery.
