Temperature-Salinity Criterion for Inhibition of Deep Convection
Publisher: American Meteorological Society
Abstract: Malmberg's salinity criterion for the inhibition of oceanic deep convection is extended here to account for increases in salinity caused by evaporation brine rejection, and mixed-layer deepening. Roughly speaking, accounting ...
A Laterally Averaged Nonhydrostatic Ocean Model
Publisher: American Meteorological Society
Abstract: A laterally averaged nonhydrostatic model for stratified flow in dynamically narrow domains is presented. Averaging laterally yields the computational efficiency of a two-dimensional model, while retaining some effects ...
Effect of Baroclinicity on Double-Diffusive Interleaving
Publisher: American Meteorological Society
Abstract: Although ocean fronts are often baroclinic, existing models of double-diffusive interleaving have ignored such baroclinic effects as velocity shear and horizontal density gradients. To determine the importance of these ...
Identifying Overturns in CTD Profiles
Publisher: American Meteorological Society
Abstract: The authors propose a scheme to test whether inversions in CTD density profiles are caused by overturning motions (from which mixing rates may be inferred) or by measurement noise. Following a common practice, possible ...
A Basinwide Estimate of Vertical Mixing in the Upper Pycnocline: Spreading of Bomb Tritium in the North Pacific Ocean
Publisher: American Meteorological Society
Abstract: The vertical diffusivity KV in the upper half-kilometer of the North Pacific subtropical pycnocline is estimated from observations of the spreading rate of anthropogenic tritium. The calculation is based on approximately ...
