RISTropical Subsurface Salinity and Tritium Distributions in the Pacific: Their Differences and Formation Mechanisms
Publisher: American Meteorological Society
Abstract: While high salinity water extends to the equator in the upper thermocline of the Pacific in the Southern Hemisphere (SH), it hits the western boundary (WB) farther north of the equator in the Northern Hemisphere (NH), ...
Upper-Ocean Mixed Layer and Wintertime Sea Surface Temperature Anomalies in the North Pacific
Publisher: American Meteorological Society
Abstract: In the North Pacific, the wintertime sea surface temperature anomaly (SSTA), which is represented by March (SSTAMar), when the upper-ocean mixed layer depth (hMar) reaches its maximum, is formed by the anomalous surface ...
Formation Mechanism for Isopycnal Temperature–Salinity Anomalies Propagating from the Eastern South Pacific to the Equatorial Region
Publisher: American Meteorological Society
Abstract: Equatorward propagation of temperature?salinity (or spiciness) anomalies on an isopycnal surface emanating from the eastern subtropical South Pacific and their formation mechanism are investigated based on a hindcast ...
Covariations of Sea Surface Temperature and Wind over the Kuroshio and Its Extension: Evidence for Ocean-to-Atmosphere Feedback
Publisher: American Meteorological Society
Abstract: Satellite microwave measurements are analyzed, revealing robust covariability in sea surface temperature (SST) and wind speed over the Kuroshio Extension (KE) east of Japan. Ocean hydrodynamic instabilities cause the KE ...
Seasonality of the Kuroshio Path Destabilization Phenomenon in the Okinawa Trough: A Numerical Study of Its Mechanism
Publisher: American Meteorological Society
Abstract: Previous observations have indicated that the Kuroshio?s path in the northern Okinawa Trough of the East China Sea is destabilized and accompanied by meanders with periods of 1?3 months during the winter?spring period. The ...
Interannual-to-Decadal Variability in the Oyashio and Its Influence on Temperature in the Subarctic Frontal Zone: An Eddy-Resolving OGCM Simulation
Publisher: American Meteorological Society
Abstract: Output of an eddy-resolving OGCM simulation is used to investigate mechanisms for interannual-to-decadal variability in the Oyashio and its influence on the subarctic frontal zone in the western North Pacific. Lag correlation ...
Influences of the Kuroshio/Oyashio Extensions on Air–Sea Heat Exchanges and Storm-Track Activity as Revealed in Regional Atmospheric Model Simulations for the 2003/04 Cold Season
Publisher: American Meteorological Society
Abstract: Influences of oceanic fronts in the Kuroshio and Oyashio Extension (KOE) region on the overlying atmosphere are investigated by comparing a pair of atmospheric regional model hindcast experiments for the 2003/04 cold season, ...
Potential Predictability of Interannual Variability in the Kuroshio Extension Jet Speed in an Eddy-Resolving OGCM
Publisher: American Meteorological Society
Abstract: ariability in the Kuroshio Extension (KE) jet speed has been considered to impact the upper-ocean ecosystem. This study investigates potential predictability of interannual variability in the KE jet speed that could arise ...
Air–Sea Interaction over the Eastern Pacific Warm Pool: Gap Winds, Thermocline Dome, and Atmospheric Convection
Publisher: American Meteorological Society
Abstract: High-resolution satellite observations are used to investigate air?sea interaction over the eastern Pacific warm pool. In winter, strong wind jets develop over the Gulfs of Tehuantepec, Papagayo, and Panama, accelerated ...
Decadal Variability in the Kuroshio–Oyashio Extension Simulated in an Eddy-Resolving OGCM
Publisher: American Meteorological Society
Abstract: Through analysis of a hindcast integration of an eddy-resolving quasi-global ocean general circulation model, decadal variability in the Kuroshio?Oyashio Extension region is investigated, with particular emphasis on that ...
