Abstract: A quasigeostrophic two-layer model of flow over finite topography is developed. The topography is a right circular cylinder that extends through the lower layer and an order Rossby number amount into the upper layer (finite ...

Abstract: The effect of continental rises on the wind-driven circulation is investigated by developing a modification to the Rhines and Young theory and by running a three-layer eddy-resolving quasigeostrophic numerical model. ...

Abstract: Solutions and energetics for nonlinear geostrophic adjustment with an initial height perturbation of the order of the total fluid depth are computed and compared to solutions derived assuming linear dynamics. Both axisymmetric ...

Abstract: Laboratory experiments show that ageostrophic instability can ?break up? a parallel flow into a sequence of axisymmetric eddies. This is a plausible scenario for the generation of sub-mesoscale coherent Vortices (SCVs). ...

Abstract: bservations of thermosteric sea level (TSL) from hydrographic data, equivalent water thickness (EWT) from the Gravity Recovery and Climate Experiment (GRACE), and altimetric sea surface height (SSH) are used to infer ...

Abstract: his study explores the utility of the thin-plate spline (TPS) as a mapping procedure for oceanographic sections of bottle data in comparison with objective mapping (OM), sometimes referred to as objective interpolation. ...

Abstract: ropical instability vortices (TIVs) in the equatorial Pacific exhibit energetic horizontal and vertical circulation characterized by regions of high Rossby number and low Richardson number. Their strong anticyclonic vorticity ...

Abstract: he Gulf Stream region is a primary location for midlatitude storm cyclogenesis and growth. However, the influence of sea surface temperature (SST) on storms in the region is still under question, particularly after a storm ...

Abstract: ecent observations of Arctic sea ice show that the decrease in summer ice cover over the last few decades has occurred in conjunction with a significant loss of multiyear ice. The transition to an Arctic that is populated ...
