Capture and Resonant Forcing of Solitary Waves by the Interaction of a Baroclinic Current with Topography
Publisher: American Meteorological Society
Abstract: The authors have demonstrated that a large amplitude, nearly stationary solitary wave can be induced either by direct resonant forcing or by the capture of a traveling wave over the forcing region, using a two-layer model ...
Generation of Mesoscale Variability by Resonant Interaction between a Baroclinic Current and Localized Topography
Publisher: American Meteorological Society
Abstract: The resonant interaction of a longshore baroclinic current with a topographic feature is investigated, using a quasi-geostrophic two-layer model, where the lower layer is assumed to be deep but is not stagnant. In this ...
The Formation of Coherent Structures in the Context of Blocking
Publisher: American Meteorological Society
Abstract: It is shown that the interaction of long, weakly nonlinear, quasigeostrophic baroclinic waves can be described by a pair of linearly coupled Korteweg?de Vries equations. Baroclinic energy conversion is investigated as the ...
The Effect of Topography on the Dynamics of Interacting Solitary Waves in the Context of Atmospheric Blocking
Publisher: American Meteorological Society
Abstract: It is shown that the influence of topography on the interaction of long, weakly nonlinear, quasigeostrophic baroclinic waves can be described by a pair of linearly coupled Korteweg?de Vries equations, with a forcing term ...
Effects of Friction on a Localized Structure in a Baroclinic Current
Publisher: American Meteorological Society
Abstract: In this paper, the effects of bottom and interfacial friction on localized baroclinic instability are discussed in the weakly nonlinear, long-wave limit. Using a quasigeostrophic two-layer model in which the lower layer ...
A Modal Analysis of Coastally Trapped Waves Generated by Tropical Cyclones
Publisher: American Meteorological Society
Abstract: The authors use numerical simulations of the shallow-water equations to study the generation of coastally trapped waves by localized forcing mechanisms. The model parameters are chosen to be typical for coastal ocean ...
Nonlinear Disintegration of the Internal Tide
Publisher: American Meteorological Society
Abstract: The disintegration of a first-mode internal tide into shorter solitary-like waves is considered. Since observations frequently show both tides and waves with amplitudes beyond the restrictions of weakly nonlinear theory, ...
Modelling of Polarity Change in a Nonlinear Internal Wave Train in Laoshan Bay
Publisher: American Meteorological Society
Abstract: here are now several observations of internal solitary waves passing through a critical point where the coefficient of the quadratic nonlinear term in the variable coefficient Korteweg?de Vries equation changes sign, ...
A Numerical Study of the Storm Surge Generated by Tropical Cyclone Jane
Publisher: American Meteorological Society
Abstract: In 1983 Tropical Cyclone Jane crossed the North West Coast of Australia generating a storm surge. Currents associated with this storm surge were recorded at two offshore moorings south of the cyclone track. The data from ...
A Nondivergent Barotropic Model for Wind-Driven Circulation in a Closed Region
Publisher: American Meteorological Society
Abstract: An analytical model is developed for nondivergent barotropic flow in a rectangular region, with depth contours parallel to the longshore boundary. The model is linear, with flow forced by wind stress and subject to dissipation ...
