RISA Modification of the Garrett–Munk Internal Wave Spectrum
Publisher: American Meteorological Society
Abstract: The Garrett?Munk (GM) spectrum continues to be a useful description of the oceanic internal wave field. However, there are several inconsistencies and ambiguities that make it difficult to use in comparing internal wave ...
Near-Inertial Energy Propagation from the Mixed Layer: Theoretical Considerations
Publisher: American Meteorological Society
Abstract: Wind-generated inertial currents can radiate from the mixed layer as horizontally and vertically propagating new-inertial internal gravity waves. To study the timescale of the decay of mixed layer energy and the magnitude ...
Near-Inertial Wave Propagation into the Pycnocline during Ocean Storms: Observations and Model Comparison
Publisher: American Meteorological Society
Abstract: Observations of near-inertial oscillations collected during the Ocean Storms Experiment in the northeast Pacific Ocean are compared with results from a linear, numerical model on a ? plane, developed by Zervakis and Levine. ...
A Statistical Description of Temperature Finestructure in the Presence of Internal Waves
Publisher: American Meteorological Society
Abstract: We have developed a statistical model describing a random field of internal waves passively oscillating a random, locally horizontally uniform temperature finestructure. Here we define finestructure to be non-internal ...
A Correction to the Baroclinic Pressure Gradient Term in the Princeton Ocean Model
Publisher: American Meteorological Society
Abstract: An error in the calculation of the baroclinic pressure gradient term in the Princeton Ocean Model (POM) was identified while modeling the M2 tidal current near its critical latitude in the southern Weddell Sea. The error ...
Tidally Forced Internal Waves and Overturns Observed on a Slope: Results from HOME
Publisher: American Meteorological Society
Abstract: Tidal mixing over a slope was explored using moored time series observations on Kaena Ridge extending northwest from Oahu, Hawaii, during the Survey component of the Hawaii Ocean Mixing Experiment (HOME). A mooring was ...
Internal Waves in the Arctic Ocean: Comparison with Lower-Latitude Observations
Publisher: American Meteorological Society
Abstract: A thermistor chain was moored below the pack ice from 50?150 m in the Arctic Ocean for five days in 1981. Oscillations in temperature are attributed to the vertical dispalcement of internal waves. The spectral shape of ...
Internal Waves in the Upper Ocean During MILE
Publisher: American Meteorological Society
Abstract: We describe the spectral analysis of temperature and velocity measurements made in the northeast Pacific as part of the Mixed Layer Experiment (MILE) and attempt to relate the observed fluctuations to internal-wave models ...
The Application of Internal-Wave Dissipation Models to a Region of Strong Mixing
Publisher: American Meteorological Society
Abstract: Several models now exist for predicting the dissipation rate of turbulent kinetic energy, ?, in the oceanic thermocline as a function of the large-scale properties of the internal gravity wave field. These models are based ...
Upper-Ocean Inertial Currents Forced by a Strong Storm. Part I: Data and Comparisons with Linear Theory
Publisher: American Meteorological Society
Abstract: A strong, isolated October storm generated 0.35?0.7 m s?1 inertia] frequency currents in the 40-m deep mixed layer of a 300 km?300 km region of the northeast Pacific Ocean. The authors describe the evolution of these ...
