Influence of forced near-inertial motion on the kinetic energy of a nearly-geostrophic flow
The effect of forced near-inertial motion on the kinetic energy budget of a turbulent, geostrophic background flow is examined using a primitive equation ocean circulation model. Balanced and unbalanced parts of the flow are taken to be equivalent to lowand high-passed filtered versions of the model fields, and the Reynolds stresses associated with the high-passed, predominantly near-inertial p...
متن کاملOrganization of near - inertial energy by an eddy field
We propose an analytical solution for the evolution of the spatial variability of wind-forced inertial energy in the presence of an oceanic mesoscale eddy field. The solution requires knowledge of only the stream function of the eddy field and the Rossby radii of the normal modes associated with the near-inertial oscillations. It also shows that, when the vorticity spectrum slope is shallower t...
متن کاملNear-inertial internal Poincare waves in Lake Michigan: Seasonal variability and effects on lateral dispersion and turbulent mixing
Choi, Jun M. Ph.D., Purdue University, May 2015. Near-inertial internal Poincaré waves in Lake Michigan: Seasonal variability and effects on lateral dispersion and turbulent mixing. Major Professor: Cary D. Troy. A dominant physical process in stratified Lake Michigan is near-inertial internal Poincaré waves. The near-inertial internal Poincaré waves is described as locally quasi-uniform curren...
متن کاملObservations of near-inertial current variability on the New England shelf
[1] Observations from the Coastal Mixing and Optics (CMO) moored array (deployed from August 1996 through June 1997) and supplemental moored observations are used to describe near-inertial current variability over the New England shelf. Near-inertial band current variance comprises 10–20% of the total observed current variance, and has episodic peak speeds exceeding 30 cm s . Near-inertial curr...
متن کاملEvolution 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...
