Transport by deep convection in basin-scale geostrophic circulation: Turbulence-resolving simulations

Vreugdenhil, Catherine; Gayen, Bishakhdatta; Griffiths, Ross


Direct numerical simulations are used to investigate the nature of fully resolved small-scale convection and its role in large-scale circulation in a rotating f-plane rectangular basin with imposed surface temperature difference. The large-scale circulation has a horizontal geostrophic component and a deep vertical overturning. This paper focuses on convective circulation with no wind stress, and buoyancy forcing sufficiently strong to ensure turbulent convection within the thermal boundary...[Show more]
