Near-Surface Turbulence and Air-Water Gas Transfer

摘要

The near-surface turbulence generated beneath wind-generated waves and its influence on air-water gas transfer rate is investigated. Vertical profiles of the turbulent kinetic energy show that a layer of enhanced turbulence is formed within the crest-trough regions. A strong correlation is observed between the air-water gas transfer velocity and the near-surface turbulent kinetic energy indicating that the near-surface turbulence plays an important role in enhancing the air-water gas transfer.
