Coastal-trapped Wave Scattering into and out of Straits and Bays
Publisher: American Meteorological Society
Abstract: A theory for the generation of coastal-trapped waves (CTWs) by an oscillatory coastal flux through a strait is extended so as to make velocity, pressure and energy flux everywhere continuous. This development is achieved ...
A Review of Relative Diffusion Analysis and Results
Publisher: American Meteorological Society
Abstract: Some confusion in the nature and difference between absolute and relative diffusion is found in the work of Kao and Al-Gain (1968) and Kirwan et al. (1978). It is shown that the relative diffusion analysis used by these ...
Energetics of Linear Geostrophic Adjustment
Publisher: American Meteorological Society
Abstract: The potential and kinetic energy spectra following geostrophic adjustment of a barotropic fluid are determined as functions of the spectrum of arbitrary initial sea level or velocity. Remarkably, the functional dependences ...
Wind-Forced Upwelling: The Role of the Surface Mixed Layer
Publisher: American Meteorological Society
Abstract: A numerical study is made of the dynamics of the circulation that arises from forcing by a steady, uniform alongshore wind over a uniform zonal shelf in the Southern Hemisphere. The results show that most of the upwelling ...
The Forcing of Low Frequency Motions within Bass Strait
Publisher: American Meteorological Society
Abstract: Three months of coincident sea-level and current meter data collected during the autumn of 1984 is analyzed so as to determine the relative importance of local wind stress and coastal-trapped waves (CTWs), incident from ...
The Mean Summertime Circulation along Australia's Southern Shelves: A Numerical Study
Publisher: American Meteorological Society
Abstract: For the first time, a high-resolution regional model is developed for the slope and shelf circulation within the Great Australian Bight and for the Gulfs region of South Australia. The results indicate the extent, nature, ...
Aspects of the Mean Wintertime Circulation along Australia's Southern Shelves: Numerical Studies
Publisher: American Meteorological Society
Abstract: A high-resolution numerical model is used to study the mean wintertime shelf-slope circulation between the Gulfs of South Australia and the west coast of Tasmania. The mean downwelling-favorable winds for the region result ...
Wind-Forced Downwelling Slope Currents: A Numerical Study
Publisher: American Meteorological Society
Abstract: A study is made of the dynamics of slope currents that arise from a steady, constant alongshore wind over a uniform shelf. Over the first 10?20 days, the evolution of the downwelled system on an f plane is qualitatively ...
The Scattering of Long Coastal-Trapped Waves in Frictional Seas
Publisher: American Meteorological Society
Abstract: The scattering of coastal-trapped waves (CTWs) by a region of irregular shelf bathymetry is determined from a circulation integral of the depth-integrated momentum equations. For relatively weak stratification the conservation ...
