RISCan Reflected Extra-equatorial Rossby Waves Drive ENSO?
Publisher: American Meteorological Society
Abstract: The possibility that the evolution of the ENSO phenomenon is determined by the reflection of extra-equatorial Rossby waves from the western boundary into the equatorial waveguide has been a subject of recent debate. ...
EOF Representations of the Madden–Julian Oscillation and Its Connection with ENSO
Publisher: American Meteorological Society
Abstract: Although recent El Niño events have seen the occurrence of strong intraseasonal winds apparently associated with the Madden?Julian oscillation (MJO), the usual indices of interannual variability of the MJO are uncorrelated ...
Mean Three-Dimensional Circulation in the Northeast Tropical Pacific
Publisher: American Meteorological Society
Abstract: Historical XBT data are used to construct a mean climatology of the three-dimensional geostrophic circulation in the northeast tropical Pacific (southwest of Mexico and Central America) and are diagnosed based on linear ...
Mean Three-Dimensional Circulation in the Northeast Tropical Pacific
Publisher: American Meteorological Society
Abstract: Historical XBT data are used to construct a mean climatology of the three-dimensional geostrophic circulation in the northeast tropical Pacific (southwest of Mexico and Central America) and are diagnosed based on linear ...
Interannual Variability of the Subsurface High Salinity Tongue South of the Equator at 165°E
Publisher: American Meteorological Society
Abstract: 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 high salinity water ...
ENSO and Short-Term Variability of the South Equatorial Current Entering the Coral Sea
Publisher: American Meteorological Society
Abstract: istorical section data extending to 1985 are used to estimate the interannual variability of transport entering the Coral Sea between New Caledonia and the Solomon Islands. Typical magnitudes of this variability are ±5?8 ...
The Annual Cycle of Circulation of the Southwest Subtropical Pacific, Analyzed in an Ocean GCM
Publisher: American Meteorological Society
Abstract: An ocean GCM, interpreted in light of linear models and sparse observations, is used to diagnose the dynamics of the annual cycle of circulation in the western boundary current system of the southwest Pacific Ocean. The ...
Rectification of the Madden–Julian Oscillation into the ENSO Cycle
Publisher: American Meteorological Society
Abstract: An ocean general circulation model, forced with idealized, purely oscillating wind stresses over the western equatorial Pacific similar to those observed during the Madden?Julian oscillation (MJO), developed rectified ...
Near-Surface Shear Flow in the Tropical Pacific Cold Tongue Front
Publisher: American Meteorological Society
Abstract: Near-surface shear in the Pacific cold tongue front at 2°N, 140°W was measured using a set of five moored current meters between 5 and 25 m for nine months during 2004?05. Mean near-surface currents were strongly westward ...
Three-Dimensional Structure of Tropical Cells in the Central Equatorial Pacific Ocean
Publisher: American Meteorological Society
Abstract: The shallow tropical cells (TCs) in the central equatorial Pacific Ocean are characterized by strong equatorial upwelling, near-surface wind-driven poleward flow, downwelling near the cold tongue boundaries, and equatorward ...
