Energy Trapping near the Equator in a Numerical Ocean Model
Energy Trapping Equator Numerical Ocean Model
2009/2/16
The trapped equatorial standing modes described theoretically by Gent (1979) are reproduced in a single vertical-mode numerical ocean model. integrations are carried out in domains whose longitudinal ...
Annual Variation in the Slope of the 14°C Isotherm along the Equator in the Pacific Ocean
Annual Variation Pacific Ocean 14°C Isotherm
2009/2/13
The annual variation in the depth of the 14°C isotherm is described on the basis of the mechanical and expendable bathythermographic data in the archives of the National Oceanographic Data Center. The...
Upper Ocean Shear and Density Variability at the Equator during TROPIC HEAT
Upper Ocean Shear TROPIC HEAT Density Variability
2009/1/8
A four and one-half day time series of upper-ocean shear and density observations was collected in the tropical Pacific Ocean in November 1984. The measurements were made on the equator at 139°50′W du...
Observations of 20-Day Period Meridional Current Oscillations in the Upper Ocean along the Pacific Equator
Meridional Current Upper Ocean Pacific Equator
2009/1/6
Prominent oscillations of the meridional current, with a mean period of approximately 20 days, have been observed in the upper ocean over several years from May 1979 to October 1985 using moored curre...
Zonal Momentum Balance at the Equator
Zonal Momentum Balance Equator zonal equatorial wind stress
2008/12/30
The conventional view of equatorial dynamics requires that the zonal equatorial wind stress be balanced, in the mean, by the vertical integral of “large-scale” terms, such as the zonal pressure gradie...
Double-Diffusive Interleaving at the Equator
Double-Diffusive Interleaving Equator water masses
2008/12/24
A theory for the observed interleaving of water masses at the equator is presented. Unlike layers at midlatitudes, individual layers are observed to be coherent over horizontal scales of hundreds of k...
Turbulence and Internal Waves at the Equator. Part II：Details of a Single Event
Internal Waves Equator Equator Single Event
2008/12/23
In the low Richardson number shear flow above the Pacific Equatorial Undercurrent, a single vertical microstructure profile intersected the overturning crest of a packet of high horizontal wavenumber ...
Turbulence and Internal Waves at the Equator. Part I：Statistics from Towed Thermistors and a Microstructure Profiler
Internal Waves Equator Microstructure Profiler Towed Thermistors
2008/12/23
High correlations between turbulent dissipation rates and high-wavenumber internal waves and the high values of turbulent dissipation associated with internal wave activity suggest that internal waves...
Crossing of the Equator by the Deep Western Boundary Current in the Western Atlantic Ocean
deep western boundary current North Atlantic Deep Water Western Atlantic Ocean
2008/12/19
Property distributions and geostrophic shear from a hydrographic section near 37°W in the Atlantic Ocean show the deep western boundary current (DWBC) in the North Atlantic Deep Water (NADW) establish...
Waves along the Equator in the Atlantic
tropical instability wave complex empirical orthogonal function
2008/12/3
Spectra of two hundred days of data from five inverted echo sounders deployed along the equator in 1983–84 and a thousand days of 30 crossings of the equator by the TOPEX/POSEIDON altimeter in 1993–95...
Interannual Variability of the Subsurface High Salinity Tongue South of the Equator at 165°E
Interannual Variability Subsurface High Salinity Tongue South of the Equator 165°E
2008/7/17
A 14-yr time series of salinity at thermocline level was constructed from repeated meridional CTD sections (averaging about 110 days apart) spanning the equator along 165°E during 1984–97. A tongue of...
Balanced Ocean-Data Assimilation near the Equator
Balanced Ocean-Data Assimilation Equator
2008/6/16
The question is addressed whether using unbalanced updates in ocean-data assimilation schemes for seasonal forecasting systems can result in a relatively poor simulation of zonal currents. An assimila...
