Equatorward Spreading of a Passive Tracer with Application to North Pacific Interdecadal Temperature Variations

A simulation is conducted with a realistic ocean general circulation model to investigate the three dimensional spreading of a passive tracer prescribed at the sea surface with the same distribution as the interdecadal sea surface temperature (SST) anomalies observed in the North Pacific. The tracers reaching the equator have the same sign as the major oval-shaped SST anomaly pattern in the cen...

Propagation of North Pacific interdecadal subsurface temperature anomalies in an ocean GCM

Propagation of subsurface North Pacific interdecadal variations is investigated with an ocean general circulation model forced by observed sea surface temperature anomalies. Subsurface temperature anomalies subducted in the central subtropical North Pacific take a more westward pathway than a passive “temperature” tracer and reach the western boundary to the north of the bifurcation latitude. T...

Interannual variations in low potential vorticity water and the subtropical countercurrent in an eddy-resolving OGCM

Interannual-to-decadal variations in the subtropical countercurrent (STCC) and low-potential vorticity (PV) water and their relations in the North Pacific Ocean are investigated based on a 60-year-long hindcast integration of an eddy-resolving ocean general circulation model. The interdecadal intensification of STCC is associated with negative PV anomalies to the north on isopycnals beneath, by...

A Theory of Interdecadal Climate Variability of the North Pacific Ocean–Atmosphere System*

A linear coupled model for the atmosphere–upper-ocean system is proposed to highlight the mechanisms of decadal to interdecadal climate variability in the North Pacific. In this model, wind stress anomalies over the North Pacific are related to anomalies in the meridional temperature gradient of the upper ocean. The latter depends upon air–sea thermodynamical feedbacks and meridional heat trans...

Seasonal variation of eddy kinetic energy of the North Pacific Subtropical Countercurrent simulated by an eddy-resolving OGCM

[1] The seasonal variation of eddy kinetic energy (EKE) of the North Pacific Subtropical Countercurrent (STCC) was investigated by analyzing the data from an eddy-resolving OGCM with the horizontal resolution 1/12 in comparison with satellite altimetry data. Although the annual cycle of simulated EKE of the whole STCC domain showed agreement with satellite data, with a maximum in spring and a m...
