论文摘要

了解气候变化将如何影响海洋流体运输对于环境应用和人类活动至关重要。然而,缺少气候变化对中尺度搅拌和运输地面海洋的影响的概要表征。为了弥合这一差距,我们使用网络理论方法利用地中海盆地的高分辨率,完全耦合的气候模型。我们预测下个世纪的水平搅拌和动能的显着增加,这可能是由于可用势能的增加。盆地尺度运输模式的未来演变暗示了主要流体动力省的重排,该省份定义为表面海洋的区域,内部混合良好,但在其边界上的跨流量很小。这导致省份大小的异质性增加,内部混合更强。我们的方法可以很容易地应用于其他海洋地区,为当前和未来的海洋空间规划提供信息。

Understanding how climate change will affect oceanic fluid transport is crucial for environmental applications and human activities. However, a synoptic characterization of the influence of climate change on mesoscale stirring and transport in the surface ocean is missing. To bridge this gap, we exploit a high-resolution, fully-coupled climate model of the Mediterranean basin using a Network Theory approach. We project significant increases of horizontal stirring and kinetic energies in the next century, likely due to increments of available potential energy. The future evolution of basin-scale transport patterns hint at a rearrangement of the main hydrodynamic provinces, defined as regions of the surface ocean that are well-mixed internally but with minimal cross-flow across their boundaries. This results in increased heterogeneity of province sizes and stronger mixing in their interiors. Our approach can be readily applied to other oceanic regions, providing information for the present and future marine spatial planning.
