Interannual and Decadal Variability in the Tropical and Midlatitude Pacific Ocean

Forty-four years of mechanical and expendable bathythermograph observations are assimilated into a general circulation model of the Pacific Ocean. The model is run from 1950 through 1993 with forcing at the surface from observed monthly mean wind stress and temperature. The resulting analysis is used to describe the spatial and temporal patterns of variability at interannual and decadal periods...

The interannual variability in the tropical Indian Ocean as simulated by a CGCM

The interannual variability in the tropical Indian Ocean, and in particular the Indian Ocean dipole mode (IODM), is investigated using both observations and a multi-decadal simulations performed by the coupled atmosphere–ocean general circulation model SINTEX. Overall, the characteristics of the simulated IODM are close to the features of the observed mode. Evidence of significant correlations ...

Interdecadal Amplitude Modulation of El Ni~ no–Southern Oscillation and Its Impact on Tropical Pacific Decadal Variability*

The amplitude of El Ni~ no–Southern Oscillation (ENSO) displays pronounced interdecadal modulations in observations. The mechanisms for the amplitude modulation are investigated using a 2000-yr preindustrial control integration from the Geophysical Fluid Dynamics Laboratory Climate Model, version 2.1 (GFDL CM2.1). ENSO amplitude modulation is highly correlated with the second empirical orthogon...

Rethinking the Ocean’s Role in the Southern Oscillation

The Southern Oscillation (SO) is usually described as the atmospheric component of the dynamically coupled El Niño–Southern Oscillation phenomenon. The contention in this work, however, is that dynamical coupling is not required to produce the SO. Simulations with atmospheric general circulation models that have varying degrees of coupling to the ocean are used to show that the SO emerges as a ...

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...
