Summary

The essential features of the steady circulation of the western Mediterranean are reproduced by means of a vertically integrated model. In the framework of barotropic theory, it is shown how the effects of the geometry of the basin, including the islands, of the variable bottom topography and of the forcing of the flow at the Gibraltar Strait concur in determining the circulation pattern. Some observed features in particular regions, such as the Ligurian Sea, which are not reproduced by the model, indicate where baroclinic and/or wind-driven dynamics are likely to dominate.

Riassunto

Le principali caratteristiche della circolazione stazionaria del Mediterraneo occidentale sono riprodotte tramite und modello integrato verticalmente. Si mostra come, nell'ambito della teoria barotropica, gli effetti della geometria del bacino, inclusa quella delle isole, di una topografia di fondo variabile e della forzatura del flusso allo stretto di Gibilterra concorrono a determinare i vari aspetti della circolazione. Alcuni aspetti locali della circolazione che non sono riprodotti dal modello in particolari regioni, come il Mar Ligure, sono indicativi di dove la dinamica baroclina e/o la forzatura del vento sono da considerarsi dominanti.

Резюме

Существенные особенности устойчивой циркуляции в западной части Средиземного моря могут быть воспроизведены с помощью вертикально проинтегрированной модели. В рамках баротропной теории показывается, как зффекты, связанные с геометрией бассейна, включая острова, и изменяемой топографией дна и силой течния в Гибралтарском проливе, влияют на определение картины циркляции. Некоторые набюдаемые особенности в отдельных областях, таких как Лигурийское море, которые не могут быть воспроизведены с помощью зтой модели, указывают на то, что, по-видимому, диминирует бароклиинная и/или ветряная динамика.
