Effect of drake passage on the global thermohaline circulation

摘要: Abstract The Ekman divergence around Antarctica raises a large amount of deep water to the ocean's surface. regional transport moves upwelled northward out circumpolar zone. and surface drift combine, in effect, remove from interior ocean. This wind-driven removal process is facilitated by unique dynamic constraint operating latitude band containing Drake Passage. Through simple model sensitivity experiment we show that upwelling belt may be quantitatively related formation new northern North Atlantic. These results stronger winds south can induce more north outflow through South fact southern hemisphere might influence Atlantic brings into question long-standing notions about forces drive thermohaline circulation.
