Surface wave dynamics effects at multiple scales in the Mediterranean Sea
[eng] Wind generated waves are crucial to transfer energy and momentum from the atmosphere to the sea surface, redistributing and transporting such energy to remote areas of the ocean. Waves induce ventilation in the ocean upper layer, enhancing vertical mixing and producing vertical transport of bi...

[eng] Wind generated waves are crucial to transfer energy and momentum from the atmosphere to the sea surface, redistributing and transporting such energy to remote areas of the ocean. Waves induce ventilation in the ocean upper layer, enhancing vertical mixing and producing vertical transport of biogeochemical tracers. When waves reach coastal areas they dissipate energy through viscous damping at the bottom and eventually by breaking, resulting in morphological changes of the bathymetry, sediment transport and erosion. The general objective of this Thesis is to perform a characterization of spatiotemporal variability of surface ocean waves, and to study their effect on the dynamics at the upper layers and at a coastal system. In particular, we analyze the large scale variability of the extreme wave climate in the Mediterranean Sea and the North Atlantic Ocean. We compute the monthly extreme waves analyzing their inter-annual variability. Then, at regional scale, we study the regional impact of the wind and wave induced velocity on the total surface dynamics at different sub-regions of the Mediterranean Sea from the Eulerian and Lagrangian standpoints.
