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.

Risk assessment of oil spills in the Chinese Bohai Sea for prevention and readiness

TL;DR: A hypothetical simulation of oil spill trajectories based on an oil spill model for 28 oil platforms in the Chinese Bohai region in 2010 is created, and a risk index in the study areas is mapped based on a combination of oil spills trajectories and shoreline susceptibility data.

An improvement of the too cold tongue in the tropical Pacific with the development of an ocean-wave-atmosphere coupled numerical model

TL;DR: Generally, the wave-induced mixing lowers the SST in the OGCM because the strengthened vertical mixing can bring more cold water upward, but in the coupled model, the non-uniformity of the space distribution in SST drop generates a horizontal gradient of...

Vertical mixing in the marginal ice zone of the northern Barents Sea—Results from numerical model experiments

TL;DR: In this paper, numerical ocean model simulations of the marginal ice zone (MIZ) of the Barents Sea have been made for the years 2003-2005, and large-scale features as well as the temporal evolution of stratification and vertical mixing, from well-mixed winter conditions to the end of the ice-free season, are described.

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.
