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

Simulated ocean response to tropical cyclones: The effect of a novel parameterization of mixing from unbroken surface waves
TL;DR: In this article, the authors investigate how the response of the ocean to tropical cyclones is affected by additional mixing from unbroken surface waves, which contributes directly to the production of turbulent kinetic energy.

Influence of the Indonesian Throughflow on the upwelling off the east coast of South Java
TL;DR: In this paper, a wave-tide-circulation coupled model is used to simulate upwelling off the south coast of Java, Indonesia, and the results show that the vertical velocity off East Java is stronger than other parts in this area.

Centuries of monthly and 3-hourly global ocean wave data for past, present, and future climate research.
TL;DR: The global monthly-mean and 3-hourly instantaneous wave parameter dataset from the FIO-ESM v2.0 CMIP6 experiments can provide the community with a vital long-term data source for scientific and engineering applications, such as wave climate research, wave-related process studies and parameterizations, as well as coastal and near-shore industry designs.

An ensemble adjustment Kalman filter study for Argo data
TL;DR: An ensemble adjustment Kalman filter system is developed to assimilate Argo profiles into the Northwest Pacific MASNUM wave-circulation coupled model, which is based on the Princeton Ocean Model, which suggests that this system is potentially capable of reconstructing oceanic data sets that are of high quality and are temporally and spatially continuous.

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.
