The Effect of Internal Wave Strain on Vertical Spectra of Fine-Structure
Internal Wave Strain Fine-Structure Vertical Spectra
2009/4/2
Vertical spectra of temperature perturbations are due to (i) internal wave displacement in the mean profile and (ii) fine-structure that would still be measured in the absence of internal waves. The f...

Internal Wave Measurements Fine-Structure
2009/3/26
Philips has pointed out that the measurement of the internal wave spectrum and coherence in a stratified medium is distinctly altered when the profile contains fine-scale layers. Garrett and Munk demo...

Internal Wave Thomson-Haskell Method
2009/3/24
The dispersion and amplitude characteristics of internal wave motion are determined by a matrix method which lends itself readily to computer analysis. A layered density structure may be chosen to fit...
Internal Wave Reflection by a Velocity Shear and Density Anomaly
Internal Wave Velocity Shear Density Anomaly
2009/3/24
Numerical solutions are obtained for the reflection of upward propagating internal waves by simple pycnocline and current shear models. Results for a simple monotonic shear and a velocity jet, with an...
