The Kuroshio and Gulf Stream, the subtropical western boundary currents of the North Pacific and North Atlantic, play important roles in meridional heat transport and ocean–atmosphere interaction processes. Using a multimodel ensemble of future projections, we show that a warmer climate intensifies the upper-layer Kuroshio, in contrast to the previously documented slowdown of the Gulf Stream. Our ocean general circulation model experiments show that the sea surface warming, not the wind… 

Contrary Responses of the Gulf Stream and the Kuroshio to Arctic Sea Ice Loss

: The impact on the Gulf Stream and Kuroshio from Arctic sea ice loss is investigated using the Community Climate System Model version 4 (CCSM4) model for their important roles during climate change.

Stronger decadal variability of the Kuroshio Extension under simulated future climate change

Understanding the behavior of western boundary current systems is crucial for predictions of biogeochemical cycles, fisheries, and basin-scale climate modes over the midlatitude oceans. Studies

Surface warming–induced global acceleration of upper ocean currents

How the ocean circulation changes in a warming climate is an important but poorly understood problem. Using a global ocean model, we decompose the problem into distinct responses to changes in sea

Western boundary circulation and coastal sea-level variability in northern hemisphere oceans

Abstract. The northwest basins of the Atlantic and Pacific oceans are regions of intense Western Boundary Currents (WBC), the Gulf Stream and the Kuroshio. The variability of these poleward currents

Future changes to the upper ocean Western Boundary Currents across two generations of climate models

Evaluated climate models from the latest and previous Climate Model Intercomparison Projects evaluate upper ocean circulation and examine future projections, focusing on subtropical and low-latitude WBCs, finding little systematic improvement in the simulation of ocean transports nor major differences in the projected changes.

Changes in the North Pacific subtropical gyre under 1.5 °C low warming scenario

Climate response to low warming scenarios that meet 2015 Paris Agreement is distinct from that to the medium/high-emissions scenarios analyzed in previous studies. The present study investigates

Rapid warming of sea surface temperature along the Kuroshio and the China coast in the East China Sea during the 20th century

It has been reported that the sea surface temperature (SST) trend of the East China Sea during the 20th century was a couple of times larger than the global mean SST trend. However, the detailed

On the characteristics and climate effects of HV-WCP events over the Kuroshio SST front during wintertime

Neglected High-frequency Variability events of the sea surface Wind Coupled with Precipitation (HV-WCP) events are revealed over the Kuroshio Sea Surface Temperature (SST) front in the East China Sea

Decoupling of the Arctic Oscillation and North Atlantic Oscillation in a warmer climate

The North Atlantic Oscillation and the Arctic Oscillation are modes of climate variability affecting temperature and precipitation in the mid-latitudes. Here we use reanalysis data and climate model

Local and remote forcing effects of oceanic eddies in the subtropical front zone on the mid-latitude atmosphere in Winter

Multiple oceanic eddies coexist in the North Pacific subtropical front zone (STFZ) in winter, which can be classified into the isolated single eddies, the combined double isotropic eddies and pairs

    Annual review of marine science

This review synthesizes paleoclimate archives, model simulations, and the instrumental record, which collectively suggest that decadal and longer-scale variability of the Gulf Stream's heat transport manifests in changes in European temperature, precipitation, and storminess.

Enhanced warming over the global subtropical western boundary currents

Subtropical western boundary currents are warm, fast-flowing currents that form on the western side of ocean basins. They carry warm tropical water to the mid-latitudes and vent large amounts of heat

Intensification and poleward shift of subtropical western boundary currents in a warming climate

A significant increase in sea surface temperature (SST) is observed over the midlatitude western boundary currents (WBCs) during the past century. However, the mechanism for this phenomenon remains

Bathymetric effect on the winter sea surface temperature and climate of the Yellow and East China Seas

Whether and how the atmosphere reacts to changes in extratropical sea surface temperature (SST) is under intense debate and this lack of understanding has been a major obstacle in the study of non‐El

Robust Warming Pattern of Global Subtropical Oceans and Its Mechanism

AbstractThe subsurface ocean response to anthropogenic climate forcing remains poorly characterized. From the Coupled Model Intercomparison Project (CMIP), a robust response of the lower thermocline

Response of Pacific subtropical‐tropical thermocline water pathways and transports to global warming

Global warming may change the thermocline water pathways and transports from the subtropics to the tropics in the Pacific Ocean, which are known to have profound implications for the El Niño‐Southern

Warming of the Global Ocean: Spatial Structure and Water-Mass Trends

AbstractThis study investigates the multidecadal warming and interannual-to-decadal heat content changes in the upper ocean (0–700 m), focusing on vertical and horizontal patterns of variability.
