Upper Ocean Response to a Hurricane
Publisher: American Meteorological Society
Abstract: The upper ocean response to a moving hurricane is studied using historical air-sea data and a three-dimensional numerical ocean model. Sea surface temperature (SST) response is emphasized. The model has a surface mixed-layer ...
Observations of a Rain-Formed Mixed Layer
Publisher: American Meteorological Society
Abstract: The structure and dynamics of a rain-formed mixed layer (ML) are studied using hourly STD and profiling current meter casts. Because the fluid beneath the rain-formed ML was vertically homogeneous, the ML buoyancy g? and ...
Internal Wave Wake of a Moving Storm. Part I. Scales, Energy Budget and Observations
Publisher: American Meteorological Society
Abstract: The ocean's baroclinic response to a steadily moving storm is analyzed using a numerical model for an inviscid, multi-layered fluid. This first part of a two-part study gives a detailed account of the response to a rapidly ...
Potential Vorticity Constraint on the Flow between Two Basins
Publisher: American Meteorological Society
Abstract: This paper examines the role of potential vorticity (PV) balance in source- and sink-driven flows between two basins. As shown in previous studies, PV advection into a basin, say a positive PV advection, requires a negative ...
Marginal Sea Overflows and the Upper Ocean Interaction
Publisher: American Meteorological Society
Abstract: Marginal sea overflows and the overlying upper ocean are coupled in the vertical by two distinct mechanisms?by an interfacial mass flux from the upper ocean to the overflow layer that accompanies entrainment and by a ...
Mixing and Spreading of the Mediterranean Outflow
Publisher: American Meteorological Society
Abstract: Hydrographic and current profiler data taken during the 1988 Gulf of Cadiz Expedition have been analyzed to diagnose the mixing, spreading, and descent of the Mediterranean outflow. The ??S properties and the thickness and ...
Momentum and Energy Balance of the Mediterranean Outflow
Publisher: American Meteorological Society
Abstract: Field data taken in the Gulf of Cadiz have been analyzed to describe some aspects of the momentum andenergy balance of the Mediterranean outflow. A crucial component of the momentum balance is the total stress(entrainment ...
The Upper-Oceanic Response to Overflows: A Mechanism for the Azores Current
Publisher: American Meteorological Society
Abstract: The oceanic response to overflows is explored using a two-layer isopycnal model. Overflows enter the open ocean as dense gravity currents that flow along and down the continental slope. While descending the slope, overflows ...
A Neutrally Buoyant, Upper Ocean Sediment Trap
Publisher: American Meteorological Society
Abstract: The authors have designed and deployed a neutrally buoyant sediment trap (NBST) intended for use in the upper ocean. The aim was to minimize hydrodynamic flow interference by making a sediment trap that drifted freely with ...
Mesoscale Variability in Denmark Strait: The PV Outflow Hypothesis
Publisher: American Meteorological Society
Abstract: The outflow through Denmark Strait shows remarkable mesoscale variability characterized by the continuous formation of intense mesoscale cyclones just south of the sill. These cyclones have a diameter of about 30 km and ...
