RISOrigin of Decadal-Scale, Eastward-Propagating Heat Content Anomalies in the North Pacific
Publisher: American Meteorological Society
Abstract: pper ocean heat content (OHC) is at the heart of natural climate variability on interannual-to-decadal time scales, providing climate memory and the source of decadal prediction skill. In the midlatitude North Pacific ...
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, ...
Influence of Local Dynamical Air–Sea Feedback Process on the Hawaiian Lee Countercurrent
Publisher: American Meteorological Society
Abstract: ocal air?sea interactions over the high sea surface temperature (SST) band along the Hawaiian Lee Countercurrent (HLCC) are examined with a focus on dynamical feedback of SST-induced wind stress to the ocean using the ...
Baiu Rainband Termination in Atmospheric and Coupled Atmosphere–Ocean Models
Publisher: American Meteorological Society
Abstract: he baiu rainband is a summer rainband stretching from eastern China through Japan toward the northwestern Pacific. The climatological termination of the baiu rainband is investigated using the Japanese 25-yr Reanalysis ...
A Coupled Decadal Prediction of the Dynamic State of the Kuroshio Extension System
Publisher: American Meteorological Society
Abstract: eing the extension of a wind-driven western boundary current, the Kuroshio Extension (KE) has long been recognized as a turbulent current system rich in large-amplitude meanders and energetic pinched-off eddies. An important ...
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 ...
Response of the Kuroshio Extension to Rossby Waves Associated with the 1970s Climate Regime Shift in a High-Resolution Ocean Model
Publisher: American Meteorological Society
Abstract: The response of the Kuroshio Extension (KE) to large-scale Rossby waves remotely excited by wind stress changes associated with the 1970s climate regime shift is studied using a high-resolution regional ocean model. Two ...
Blocking of the Kuroshio Large Meander by Baroclinic Interaction with the Izu Ridge
Publisher: American Meteorological Society
Abstract: This paper discusses the role of the Izu Ridge in blocking the Kuroshio large meander from propagating eastward across the ridge. It is shown that a combination of the sloping bottom with baroclinicity in the Kuroshio flow ...
Processes Shaping the Frontal-Scale Time-Mean Surface Wind Convergence Patterns around the Gulf Stream and Agulhas Return Current in Winter
Publisher: American Meteorological Society
Abstract: High-resolution satellite observations and numerical experiments have revealed local enhancement of time-mean surface wind convergence along the axes of warm western boundary currents and divergence slightly poleward. A ...
Modulations of North American and European Weather Variability and Extremes by Interdecadal Variability of the Atmospheric Circulation over the North Atlantic Sector
Publisher: American Meteorological Society
Abstract: The dominant mode of wintertime interdecadal covariability between subseasonal surface air temperature (SAT) variability and midtropospheric circulation over the North Atlantic sector is identified through maximum covariance ...
