Low-Frequency Reflection from a Nonmeridional Eastern Ocean Boundary and the Use of Coastal Sea Level to Monitor Eastern Pacific Equatorial Kelvin Waves
Publisher: American Meteorological Society
Abstract: Analytical theory and wind, sea level, and atmospheric pressure data were used to examine low-frequency dynamics near the equatorial eastern Pacific Ocean boundary. The analytical technique involves linking low-frequency ...
Gas Turbine Engine Health Management: Past, Present, and Future Trends
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engine diagnostic practices are as old as the gas turbine itself. Monitoring and analysis methods have progressed in sophistication over the past six decades as the gas turbine evolved in form and complexity. While much ...
Observational and Numerical Evidence for Wind-Forced Coastal Trapped Long Waves
Publisher: American Meteorological Society
Abstract: Recent work has shown that the linear, wind-forced quasi-geostrophic motion of stratified water over shelf topography can be described by a sum of modes, the amplitude of each of these modes satisfying a forced, first-order ...
Analytical Theory for the Quasi-Steady and Low-Frequency Equatorial Ocean Response to Wind Forcing: The “Tilt” and “Warm Water Volume” Modes
Publisher: American Meteorological Society
Abstract: Analytical theory is used to examine the linear response of a meridionally unbounded stratified ocean to large-scale, low-frequency wind forcing. The following results, applied mainly to the equatorial Pacific, were obtained. ...
Why Are Surface Equatorial ENSO Winds Anomalously Westerly under Anomalous Large-Scale Convection?
Publisher: American Meteorological Society
Abstract: Previous work has shown that the near-surface tropospheric response to anomalous heating can be described in terms of damped equatorial Rossby waves and a damped equatorial Kelvin wave. The zonal and meridional extent of ...
Origin of the Coastally Trapped Waves Observed during the Australian Coastal Experiment
Publisher: American Meteorological Society
Abstract: Freely propagatiug coastally trapped waves (CTWs) dominated the large alongshore-scale low-frequency variability in the Australian Coastal Experiment (ACE). Two analytical models are used to demonstrate that these waves ...
The Dynamics of Large-Scale, Wind-Driven Variations in the Antarctic Circumpolar Current
Publisher: American Meteorological Society
Abstract: A nonlinear model is developed and analytical results obtained to discuss the response of the Antarctic Circumpolar Current to wind forcing over a wide range of frequencies. The main results are as follows: (i) The nonlinear ...
Application of a Frictional Channel Flow Theory to Flow in the Prince of Wales Channel, Torres Strait
Publisher: American Meteorological Society
Abstract: Turbulent flow is considered in a narrow, constant-depth channel connecting two basins having a time-dependent sea-level difference. The bosom stress is taken to be linear rather than quadratic in velocity, even when flows ...
The Reflection of Equatorial Waves from Oceanic Boundaries
Publisher: American Meteorological Society
Abstract: Theory is developed to discuss the reflection of long equatorial waves from ocean boundaries. The main results are as follows: 1) Energy flux reflection coefficients for the reflection of equatorial waves from meridional ...
Why Is the Westward Rossby Wave Propagation from the California Coast “Too Fast”?
