RISThe General Circulation and Meridional Heat Transport of the Subtropical South Atlantic Determined by Inverse Methods
Publisher: American Meteorological Society
Abstract: Using hydrographic data of the IGY and METEOR expeditions, the inverse method of Wunsch (1978) has been applied to the subtropical South Atlantic Ocean to determine its general circulation and meridional heat transport. ...
Mass, Heat and Freshwater Fluxes in the South Indian Ocean
Publisher: American Meteorological Society
Abstract: Six hydrographic sections were used to examine the circulation and property fluxes in the South Indian Ocean from 10° to 32°S. The calculations were made by applying an inverse method to the data. In the interior of the ...
Wind-Forced Intraseasonal Sea Level Variability of the Extratropical Oceans
Publisher: American Meteorological Society
Abstract: Seven years' worth of sea level observations from the TOPEX/Poseidon altimeters and wind observations from the European Remote-Sensing Satellites (ERS-1/2) scatterometers were used to investigate the dynamics of large-scale ...
Latitudinal and Frequency Characteristics of the Westward Propagation of Large-Scale Oceanic Variability
Publisher: American Meteorological Society
Abstract: In the open ocean away from the equator, westward propagation is a ubiquitous characteristic of oceanic variability. The objectives of the study are to investigate the latitudinal dependence of the frequency of ...
Intraseasonal Variability of the Equatorial Indian Ocean Observed from Sea Surface Height, Wind, and Temperature Data
Publisher: American Meteorological Society
Abstract: The forcing of the equatorial Indian Ocean by the highly periodic monsoon wind cycle creates many interesting intraseasonal variabilities. The frequency spectrum of the wind stress observations from the European Remote ...
Interaction of Mesoscale Variability with Large-Scale Waves in the Argentine Basin
Publisher: American Meteorological Society
Abstract: The Argentine Basin of the South Atlantic Ocean is a region of complicated ocean dynamics involving a wide range of spatial and temporal scales. Previous studies reported the existence of a basin mode of topographic ...
On Correcting Radial Orbit Errors for Altimetric Satellites Using Crossover Analysis
Publisher: American Meteorological Society
Abstract: Radial orbit error, defined as the uncertainty in the geocentric altitude of a satellite, is the dominant error in the measurement of sea surface height by a satellite altimeter. Apart from a geographically dependent ...
The Effects of Altimeter Instrument Noise on the Estimation of the Wavenumber Spectrum of Sea Surface Height
Publisher: American Meteorological Society
Abstract: he wavenumber spectrum of sea surface height (SSH) observed by satellite altimetry was analyzed by Xu and Fu. The spectral shape in the wavelength range of 70?250 km was approximated by a power law, representing a regime ...
On the Transition from Profile Altimeter to Swath Altimeter for Observing Global Ocean Surface Topography
Publisher: American Meteorological Society
Abstract: onventional radar altimeter makes measurement of sea surface height (SSH) in one-dimensional profiles along the ground tracks of a satellite. Such profiles are combined via various mapping techniques to construct two-dimensional ...
On the Long-Wavelength Validation of the SWOT KaRIn Measurement
Publisher: American Meteorological Society
Abstract: AbstractThe Surface Water and Ocean Topography (SWOT) mission will measure the sea surface height (SSH) using a Ka-band radar interferometer (KaRIn) over a swath off the nadir of the satellite tracks. The mission requires ...
