Poleward-propagating near-inertial waves enabled by the western boundary current

Evolution of near-inertial waves

The three-dimensional evolution of near-inertial internal gravity waves is investigated for the case of a laterally unbounded fluid layer of constant finite depth. A general Green’s function formulation is derived which can be used to solve initial value problems or study the effect of forcing. The Green’s function is expanded in vertical normal modes, and is very singular. Convolutions with fi...

Stalling of near-inertial waves in a cyclone

[1] Observations at the edge of the Loop Current after hurricane Katrina show inertial energy amplified at a depth of approximately 600 700 m. Ray-analysis using the eddy field obtained from a numerical simulation with data assimilation suggests that the amplification is due to inertial motions stalled in a deep cyclone.

Inertial waves near corotation in 3D hydrodynamical disks

This paper concerns the interaction between non-axisymmetric inertial waves and their corotation resonances in a hydrodynamical disk. Inertial waves are of interest because they can localise in resonant cavities circumscribed by Lindblad radii, and as a consequence exhibit discrete oscillation frequencies that may be observed. It is often hypothesised that these trapped eigenmodes are affiliate...

Can near-inertial internal waves in the East Sea be observed by synthetic aperture radar?

[1] Near-inertial ( 18 hours) internal waves were observed in the mid-western part of the East Sea on May 18 and 19, 2004 using C-band Synthetic Aperture Radar (SAR) images. Current and temperature measurements obtained during the field experiment from 10 May to 9 June 2004 (IWXES2004, Internal Wave eXperiment in the East Sea), were analyzed to investigate the processes by which near-inertial i...
