Intercomparison of Quasi-Geostrophic Simulations of the Western North Atlantic Circulation with Primitive Equation Results
Western North Atlantic Circulation Primitive Equation Results
2009/2/23
The purpose of this paper is to compare two numerical models of vastly different complexity and computational requirements, which have been used recently in a number of midlatitude ocean simulations. ...
Absolute Geostrophic Velocity Determination from Historical Hydrographic Data in the Western North Atlantic
Western North Atlantic Geostrophic Velocity Historical Hydrographic Data
2009/2/18
Beta-spiral calculations are presented using averaged western North Atlantic hydrographic data from the period 1914–73. Profiles of long-term mean geostrophic flow relative to ISM db along 70°W from 2...
Variability of Potential Energy, Dynamic Height and Salinity in the Main Pycnocline of the Western North Atlantic
Potential Energy Main Pycnocline Western North Atlantic
2009/2/13
Hydrographic data in the upper 2 km from the period 1914–73 have been analyzed in the western North Atlantic (22–36°N, 66–74°W). Expendable bathythermograph (XBT) data were also analyzed and compared ...
The Structure, Dynamics, and Origin of a Small-Scale Lens of Water in the Western North Atlantic Thermocline
Local Dynamics Experiment Western North Atlantic Thermocline Small-Scale Lens
2009/1/10
A small-scale, isolated, anticyclonically rotating lens of water was observed in the western North Atlantic thermocline during the POLYMODE Local Dynamics Experiment. Using a combination of SOFAR floa...
Geographic and Temporal EddY Variability in the Western North Atlantic as Sensed by Satellite：An Eddy Generation Mechanism
Western North Atlantic Eddy Generation Mechanism Satellite
2009/1/8
This paper has two objectives: to establish the satellite-derived mesoscale sea surface temperature anomaly as a useful oceanographic measure and to use this measure to explore an eddy generation mech...
Large-Scale SST Variability in the Western North Atlantic Subtropical Convergence Zone during FASINEX. Part II：Upper Ocean Heat Balance and Frontogenesis
subtropical frontal zone sea surface temperature Upper Ocean Heat Balance Frontogenesis
2008/12/27
We analyzed the influence of wind-deriven horizontal heat advection on the large-scale [O(1000) km wavelength] variability of both the upper-ocean mixed-layer heat content and the subtropical frontal ...
Large-Scale SST Variability in the Western North Atlantic Subtropical Convergence Zone during FASINEX. Part I：Description of SST and Wind Stress Fields
Wind Stress Fields Large-Scale SST NOAA ATOLL Subtropical Convergence Zone
2008/12/27
We describe properties of large-scale fluctuations in the wind field represented by two analyses (FNOC and NOAA ATOLL), and in the SST field represented by maps derived from 5-day composite AVHRR imag...
Bottom Water Circulation in the Western North Atlantic
Water Circulation Western North Atlantic
2008/12/22
Antarctic Bottom Water flows into the western North Atlantic across the equator, shifting from the western side to the eastern side of the trough between the American continents and the Mid-Atlantic R...
Ventilation of the Deep Western Boundary Current and Abyssal Western North Atlantic: Estimates from Tritium and 3He Distributions
North Atlantic Deep Water deep western boundary current
2008/12/15
The tritium and excess 3He data from the 1981 TTO/NAS program are used to study the time scales for the ventilation of the deep western basin by recently formed North Atlantic Deep Water (NADW). The l...
Heat Flux Estimates for the Western North Atlantic. Part II：The Upper-Ocean Heat Balance
Upper-Ocean Heat Balance Western North Atlantic Heat Flux
2008/12/12
The assimilation of temperature and altimetric velocity into a numerical model of the upper-ocean mixed layer in Part I allowed an analysis of the upper ocean heat budget for the western North Atlanti...
Heat Flux Estimates for the Western North Atlantic. Part I：Assimilation of Satellite Data into a Mixed Layer Model
Heat Flux Western North Atlantic Mixed Layer Model
2008/12/12
Satellite-derived temperature and geostrophic velocities were assimilated into a mixed layer model to obtain estimates of the net surface heat flux as the residual of the upper ocean heat budget. The ...
