Near-Inertial Waves and Turbulence Driven by the Growth of Swell [PDF]

Journal of Physical Oceanography, 2020
Abstract Between 5% and 25% of the total momentum transferred between the atmosphere and ocean is transmitted via the growth of long surface gravity waves called “swell.” In this paper, we use large-eddy simulations to show that swell-transmitted momentum excites near-inertial waves and drives turbulent mixing that deepens a rotating,

Interaction of near-inertial waves with an anticyclonic vortex [PDF]

Journal of Physical Oceanography, 2021
AbstractAnticyclonic vortices focus and trap near-inertial waves so that near-inertial energy levels are elevated within the vortex core. Some aspects of this process, including the nonlinear modification of the vortex by the wave, are explained by the existence of trapped near-inertial eigenmodes.

Energy Transfer Between Mesoscale Eddies and Near‐Inertial Waves From Surface Drifter Observations

Geophysical Research Letters, 2023
Hourly satellite‐tracked surface drifter data are utilized to study energy transfer from eddies to Near‐Inertial Waves (NIWs). Spatial velocity gradients are computed from two consecutive velocity estimates derived from the same drifter, providing ...

The Generation and Propagation of Wind- and Tide-Induced Near-Inertial Waves in the Ocean

Journal of Marine Science and Engineering
Near-inertial waves (NIWs), a special form of internal waves with a frequency close to the local Coriolis frequency, are ubiquitous in the ocean. NIWs play a crucial role in ocean mixing, influencing energy transport, climate change, and biogeochemistry.

Near-Inertial Waves Induced by Typhoon Megi (2010) in the South China Sea

Journal of Marine Science and Engineering, 2021
Near-inertial waves (NIWs) are a kind of internal wave, which are usually generated by synoptic wind forcing and play an important role in the oceanic energy budget.

Refraction and Straining of Near-Inertial Waves by Barotropic Eddies [PDF]

Journal of Physical Oceanography, 2020
AbstractFast-moving synoptic-scale atmospheric disturbances produce large-scale near-inertial waves in the ocean mixed layer. In this paper, we analyze the distortion of such waves by smaller-scale barotropic eddies, with a focus on the evolution of the horizontal wavevector k under the effects of straining and refraction. The model is initialized with

Penetration of Wind-Generated Near-Inertial Waves into a Turbulent Ocean [PDF]

Journal of Physical Oceanography, 2020
AbstractAn idealized storm scenario is examined in which a wind-generated inertial wave interacts with a turbulent baroclinic quasigeostrophic flow. The flow is initialized by spinning up an Eady model with a stratification profile based on observations.

Poleward-propagating near-inertial waves enabled by the western boundary current. [PDF]

Sci Rep, 2019
Near-inertial waves (NIWs), which have clockwise (anticlockwise) rotational motion in the Northern (Southern) Hemisphere, exist everywhere in the ocean except at the equator; their frequencies are largely determined by the local inertial frequency, f. It

Interpreting Observed Interactions between Near-Inertial Waves and Mesoscale Eddies [PDF]

Journal of Physical Oceanography, 2023
The evolution of wind-generated near-inertial waves (NIWs) is known to be influenced by the mesoscale eddy field, yet it remains a challenge to disentangle the effects of this interaction in observations.

Downward Propagation and Trapping of Near-Inertial Waves by a Westward-moving Anticyclonic Eddy in the Subtropical Northwestern Pacific Ocean

Journal of Physical Oceanography, 2023
Mesoscale eddies can alter the propagation of wind-generated near-inertial waves (NIWs). Different from previous studies, the subsurface mooring observed NIWs are generated outside an anticyclonic eddy (ACE) and then interact with the arriving ACE.
