Rotating horizontal convection

B Gayen, RW Griffiths - Annual Review of Fluid Mechanics, 2022 - annualreviews.org
Global differences of temperature and buoyancy flux at the ocean surface are responsible
for small-scale convection at high latitudes, global overturning, and the top-to-bottom density …

Ocean convection

CA Vreugdenhil, B Gayen - Fluids, 2021 - mdpi.com
Ocean convection is a key mechanism that regulates heat uptake, water-mass
transformation, CO2 exchange, and nutrient transport with crucial implications for ocean …

Heat and momentum transport scalings in horizontal convection

O Shishkina, S Grossmann… - Geophysical research …, 2016 - Wiley Online Library
In a horizontal convection (HC) system heat is supplied and removed exclusively through a
single, top, or bottom, surface of a fluid layer. It is commonly agreed that in the studied …

Development of overturning circulation in sloping waterbodies due to surface cooling

HN Ulloa, CL Ramón, T Doda, A Wüest… - Journal of Fluid …, 2022 - cambridge.org

maximum density, can generate differential cooling between shallow and deep regions …

Deep-reaching global ocean overturning circulation generated by surface buoyancy forcing

A Klocker, D Munday, B Gayen, F Roquet… - Tellus A: Dynamic …, 2023 - duo.uio.no
In contrast with the atmosphere, which is heated from below by solar radiation, the ocean is
both heated and cooled from above. To drive a deep-reaching overturning circulation in this …

Stratified turbulent mixing in oscillating shear flows

SF Lewin, CP Caulfield - Journal of Fluid Mechanics, 2022 - cambridge.org
Motivated by the variation of local shear produced by internal waves in the ocean, we use

Mechanical energy budget and mixing efficiency for a radiatively heated ice-covered waterbody

HN Ulloa, A Wüest, D Bouffard - Journal of Fluid Mechanics, 2018 - cambridge.org
