The Transmission and Decay of Barotropic Topographic Rossby Waves Incident on a Continental Shelf
Barotropic Topographic Rossby Waves Continental Shelf
2009/3/7
We know that long-period (>1 day) and long-wavelength (>100 km) topographical Rossby waves can be generated by a wind acting directly on a continental shelf (Adams and Buchwald, 1969). Here we examine...
Dekameter Radar Observations of Ocean Wave Growth and Decay
Dekameter Radar Observations Ocean Wave Decay Growth
2009/2/16
Immediately following the passage of polar fronts that produced strong winds blowing away from Galveston Island and into the Gulf of Mexico, we used scattered LORAN-A radio waves, together with observ...
Temporal Rates of Growth and Decay of Microscopic and Macroscopic Surface Structures in a Wind-Wave Tank
Temporal Rates Macroscopic Surface Structures Wind-Wave Tank
2009/2/13
The distributions of water-surface slopes and wave heights were measured under suddenly started and stopped winds. The root-mean-square slopes and average wave heights are found to grow and decay expo...
A Numerical Study of Nonfrictional Decay of Mesoscale Eddies
Nonfrictional Decay Mesoscale Eddies
2009/2/7
The decay of mesoscale eddies can be attributed to either frictional dissipation of kinetic energy through viscous effects or through dispersive spreading of the different constituent Rossby wave comp...
A Comparison of Length Scales and Decay Times of Turbulence in Stably Stratified Flows
Length Scales Decay Times Stably Stratified Flows
2009/1/13
An examination of average values of a buoyancy length scale, LR = (/N3)½, and a Thorpe scale, LT, computed from vertical profiles of oceanic turbulence at 150°W in the tropical Pacific Ocean, s...
A Simple Model for the Shear-induced Decay of an Internal Solitary Wave
Internal solitary waves hear-induced Decay
2008/12/19
Internal solitary waves (ISWs) are a common feature of the coastal zone and marginal seas, especially close to shelf breaks, and are observed to mix the water column at the depth of maximum density gr...
The decay of a downward propagating near-inertial wave was observed over four days. During this short period, the energy of the near-inertial wave decreased by 70%. The shear layers produced by the wa...
On the Decay of the Meanders of Eastward Currents
Eastward Currents large-scale meanders quasi-stationary
2008/12/15
The separation of western boundary currents from the coast and their eastward extensions into the open ocean are characterized by the presence of quasi-stationary, large-scale meanders. These meanders...
Propagation and Decay of Forced and Free Baroclinic Rossby Waves in Off-Equatorial Oceans
sea surface height global ocean general circulation model
2008/12/3
Baroclinic Rossby wave motions in the off-equatorial oceans are investigated with emphasis on how eddy dissipation can influence the propagation of the height anomalies when both the forced wave respo...
Turbulence Decay and Restratification in the Equatorial Ocean Surface Layer following Nighttime Convection
Nighttime Convection Turbulence Decay Equatorial Ocean Surface Layer
2008/11/18
Although the process of restratification of the ocean surface layer at the equator following nighttime convection is similar in many ways to the process at midlatitudes, there are important difference...
Decay of Turbulence in the Upper Ocean following Sudden Isolation from Surface Forcing
Upper Ocean surface meteorology statically stable layer
2008/11/18
Measurements of velocity, hydrography, surface meteorology, and microstructure were made through several squall events during a westerly wind burst that occurred in the Western Pacific warm pool in De...
Propagation, Diffusion, and Decay of SST Anomalies beneath an Advective Atmosphere
Propagation Diffusion SST Anomalies beneath Advective Atmosphere
2008/7/1
A simple conceptual model is used to illustrate aspects of how the midlatitude atmosphere, in the absence of ocean dynamics, responds to and feeds back on sea surface temperature (SST) anomalies. In t...
Decay of Stable Warm-Core Eddies in a Layered Frontal Model（图）
Decay Warm-Core Eddies Layered Frontal Model
2008/5/28
Aspects of the decay of stable frontal warm-core eddies in the deep ocean are investigated using a new numerical layered “frontal” model that solves the nonlinear, reduced-gravity, shallow-water equat...
