Wave-induced mixing in the upper ocean: Distribution and application to a global ocean circulation model
TLDR
In this article, the wave-induced vertical viscosity (or diffusivity) Bv is defined, which can be used as a parameter to estimate the strength of waveinduced mixing.Abstract:
[1] From the Reynolds stress expression, the wave-induced vertical viscosity (or diffusivity) Bv is defined, which can be used as a parameter to estimate the strength of wave-induced mixing. In addition, a parameter D5 is introduced to represent a wave-induced mixing penetration depth. The global distribution of Bv averaged over the upper 20 m is calculated and its latitudinal transects in boreal summer and winter is discussed. The results show that in summer the wave-induced mixing is strong in the southern oceans south of 30°S, and in winter it is strong in the north Pacific and the north Atlantic north of 30°N, as well as in the southern oceans south of 40°S. Adding Bv to the vertical diffusivity in a global ocean circulation model yields a temperature structure in the upper 100 m that is closer to the observed climatology than a model without the wave-induced mixing.read more

The effects of the non-breaking surface wave-induced vertical mixing on the forecast of tropical cyclone tracks
TL;DR: In this article, three numerical experiments are implemented to investigate the effects of the real-time forecasted sea surface temperature (SST) and the non-breaking wave-induced vertical mixing (Bv) on the track forecast of all 33 tropical cyclones (TC) in the model domain area during 2008 and 2011.

Ocean near-surface layers
TL;DR: The ocean near-surface layers, such as the mixed and mixing layers, the entrainment layer, and the log layer, contain the oceans' most energetic turbulence and are critical to understanding and prediction of the oceans and the earth system as discussed by the authors .

Spatial variability of turbulent mixing in the Abyssal Ocean
TL;DR: Ocean microstructure data show that turbulent mixing in the deep Brazil Basin of the South Atlantic Ocean is weak at all depths above smooth abyssal plains and the South American Continental Rise, which implies that abyssal circulations have complex spatial structures that are linked to the underlying bathymetry.
