Aqueous surface layer flows induced by microscale breaking wind waves

摘要: Microscale breaking wind waves cover much of the surface open waters exposed to moderate forcing. Recent studies indicate that understanding nature and key features skin flows associated with these small is fundamental explaining dramatic enhancement constituent exchange occurs in their presence. We describe a laboratory study which velocity measurements were made within few hundred micrometres microscale without bubble entrainment, using flow visualization particle image velocimetry (PIV) techniques for range speed fetch conditions. Our show each experiment, mean drift directly induced by on upwind faces crests ( at crest. This variability can be attributed primarily modulation wave field, additional contributions arising from fluctuations forcing near-surface turbulence generated shear layer or influence transient breaking.
