On the Dynamics of β Plumes
Publisher: American Meteorological Society
Abstract: The dynamics of zonal recirculating flows (? plumes) driven by a source of potential vorticity, or a sink of mass, located at the eastern boundary of an ocean basin are investigated using analytical solutions of the ...
Dynamics of Two-Dimensional Turbulent Bottom Gravity Currents
Publisher: American Meteorological Society
Abstract: In light of previous numerical studies demonstrating a strong sensitivity of the strength of thermohaline circulation to the representation of overflows in ocean general circulation models, the dynamics of bottom gravity ...
Lagrangian Data Assimilation in Multilayer Primitive Equation Ocean Models
Publisher: American Meteorological Society
Abstract: Because of the increases in the realism of OGCMs and in the coverage of Lagrangian datasets in most of the world's oceans, assimilation of Lagrangian data in OGCMs emerges as a natural avenue to improve ocean state forecast ...
Emergence of Inertial Gyres in a Two-Layer Quasigeostrophic Ocean Model
Publisher: American Meteorological Society
Abstract: The emergence of Fofonoff-like flows over a wide range of dissipative parameter regimes is explored in a wind-driven two-layer quasigeostrophic model. Two regimes are found in which Fofonoff-like circulations emerge as a ...
Multivariate-Spline and Scale-Specific Solution for Variational Analyses
Publisher: American Meteorological Society
Abstract: A recipe for a cubic B-spline-based solution for multivariate variational formulation of a data analysis and assimilation problem is provided. To represent a signal whose smallest wavelength is L, the spline scale must be ...
Impact of Wind Forcing, Bottom Topography, and Inertia on Midlatitude Jet Separation in a Quasigeostrophic Model
Publisher: American Meteorological Society
Abstract: The persistence of unrealistic Gulf Stream separation in numerical models of the ocean has prompted many theories about possible mechanisms that influence the separation of a western boundary current from the coast. In ...
On the Connection between the Mediterranean Outflow and the Azores Current
Publisher: American Meteorological Society
Abstract: As the salty and dense Mediteranean overflow exits the Strait of Gibraltar and descends rapidly in the Gulf of Cadiz, it entrains the fresher overlying subtropical Atlantic Water. A minimal model is put forth in this study ...
Turbulent Mixing in the Red Sea Outflow Plume from a High-Resolution Nonhydrostatic Model
Publisher: American Meteorological Society
Abstract: Given the motivation that overflow processes, which supply source waters for most of the deep and intermediate water masses in the ocean, pose significant numerical and dynamical challenges for ocean general circulation ...
Turbulent Mixing in the Red Sea Outflow Plume from a High-Resolution Nonhydrostatic Model
Publisher: American Meteorological Society
Abstract: Given the motivation that overflow processes, which supply source waters for most of the deep and intermediate water masses in the ocean, pose significant numerical and dynamical challenges for ocean general circulation ...
Lagrangian Analysis and Predictability of Coastal and Ocean Dynamics 2000
Publisher: American Meteorological Society
Abstract: The first Lagrangian Analysis and Predictability of Coastal and Ocean Dynamics (LAPCOD) meeting took place in Ischia, Italy, 2?6 October 2000. The material presented at LAPCOD 2000 indicated both a maturing of Lagrangian-based ...
