Wave field correlations in weakly mismatched random media
Wave field correlations weakly mismatched random media
2015/7/14
This paper concerns the derivation of a Fokker-Planck equation for the correlation of two high frequency wave fields propagating in two different random media. The mismatch between therandom media nee...
The variability of the large-amplitude internal wave field on the Australian North West Shelf
Internal waves Solitary waves Internal tide Continental slope Australian North West Shelf (14–221S, 114–1261E)
2015/6/30
Observations are presented of large-amplitude internal waves (LAIWs) generated by the steepening of the internal tide on the Australian North West Shelf (NWS) over a 4-month period extending from stro...

Numerical computations indicate that the nonlinear self-interaction mechanisms, induced diffusion and elastic scattering generate a universal equilibrium spectrum of deep ocean internal waves. This sp...
The Influence of the Directional Energy Distribution on the Nonlinear Dispersion Relation in a Random Gravity Wave Field
Directional Energy Distribution Nonlinear Dispersion Relation Random Gravity Wave Field
2009/3/7
The influence of the directional distribution of wave energy on the dispersion relation is calculated numerically using various directional wave spectrum models. The results indicate that the dispersi...

Vertical Coherence Vertical Coherence Towed Sensors
2009/2/13
Constant depth and isopycnal-following tows are used to estimate the, towed vertical coherence of the internal wave field, at vertical separations of 8.5, 18, 28 and 70 m. The depths of the tows are 7...
Observations of the Horizontal Interactions between the Internal Wave Field and the Mesoscale Flow
Horizontal Interactions Internal Wave Field Mesoscale Flow
2009/2/10
Momentum and energy transfers from the mesoscale horizontal velocity shear to the internal wave field have been deduced from an analysis of a closely spaced, 25 km, moored current-meter array. The cor...

Wind-Generated Wave Field fetch-limited wave field wave breaking
2009/1/21
Measurements were made of the surface elevation of a fetch-limited wave field (fetch 7 km, wind speed about 6 m s−1). Good high-frequency response was attained by the use of a very thin, bare wi...
