Zonal and Seasonal Variations of the Near-Surface Heat Balance of the Equatorial Pacific Ocean
Near-Surface Heat Balance Equatorial Pacific Ocean
<
2009/1/12
This study calculates a detailed climatological inventory of the oceanic heat balance in the equatorial Pacific. The gridded climatology of Weare et al. is used as an estimate of net surface heating. ...
Wavenumber Spectra of Pacific Winds Measured by the Seasat Scatterometer
Seasat-A Satellite Scatterometer Wavenumber Spectra
<
2009/1/12
Vector winds measured by the Seasat-A Satellite Scatterometer (SASS) are analyzed to determine the spatial structure of oceanic surface winds over wavelengths from 200 to 2200 km. The analysis is perf...
Eddy Heat Flux in the Subtropical North Pacific
Eddy Heat Flux Subtropical North Pacific
<
2009/1/12
Meridional eddy heat flux in the subtropical North Pacific is estimated from TRANSPAC ship-of-opportunity data collected during 1976–80. Two methods are used. The first fits simple functional forms to...
The Subarctic and Northern Subtropical Fronts in the Eastern North Pacific Ocean in Spring
Subarctic Eastern North Pacific Ocean Northern Subtropical Fronts
<
2009/1/10
The subarctic and subtropical frontal zones of the eastern North Pacific Ocean were surveyed in June for five consecutive years starting in 1972. These surveys from the basis for a description of the ...
Observation of Long Equatorial Waves in the Pacific Ocean by Seasat Altimetry
Long Equatorial Waves Pacific Ocean Seasat Altimetry
<
2009/1/9
Synoptic maps of the mesoscale dynamic topography in a band between 7.5°N and 7.5°S in the Pacific Ocean are drawn from Seasat altimeter data. They show a set of eddies 600 km in diameter and 15–20 cm...

Equatorial Undercurrent South Equatorial Current South Subsurface Countercurrents
<
2009/1/9
As part of the international TOGA program, the ORSTOM Center in Nouméa (New Caledonia) initiated in January 1984 a series of semi-annual cruises along the 165°E meridian from 20°S to 10°N, across the ...
Estimates of Time and Space Scales at 300 Meters in the Midlatitude North Pacific from the TRANSPAC XBT Program
Space Scales 300 Meters TRANSPAC XBT Program
<
2009/1/9
Estimates of length and time scales of temperature variability at 300 meters in the midlatitude North Pacific are made. Data are XBT traces collected from 1976 to 1984 in the TRANSPAC Volunteer Observ...
Extraction of Mixed Layer Advection Velocities, Diffusion Coefficients, Feedback Factors and Atmospheric Forcing Parameters from the Statistical Analysis of North Pacific SST Anomaly Fields
sea surface temperature Mixed Layer Advection Velocities Diffusion Coefficients
<
2009/1/9
The statistical properties of observed North Pacific sea surface temperature (SST) anomalies are simulated by a simple mixed layer advection and diffusion model with stabilizing feedback and local sto...
Simulation of the Seasonal Cycle of the Tropical Pacific Ocean
Seasonal Cycle Tropical Pacific Ocean
<
2009/1/9
In a general circulation model of the tropical Pacific Ocean forced with climatological seasonally varying winds, equatorial upwelling and downwelling in adjacent latitudes play central roles in closi...
The Intraseasonal Oscillation in Eastern Pacific Sea Levels：How Is It Forced?
Intraseasonal Oscillation Eastern Pacific Sea Levels
<
2009/1/8
Daily sea level and surface winds at eastern Pacific shore locations and equatorial islands, together with gridded five-day averages of 850 mb winds, have been analyzed for the 1979–84 period to deter...
Interannual Variability of the Kuroshio Frontal Structure along Its Western Boundary in the North Pacific Ocean Associated with the 1982 ENSO Event
Interannual Variability North Pacific Ocean Kuroshio Frontal Structure
