Abstract: The physical mechanism underlying ENSO?s phase locking to the seasonal cycle is examined in three parameter regimes: the fast-SST limit, the fast-wave limit, and the mixed SST?wave dynamics regime. The seasonal cycle is ...

Abstract: The possibility of generating decadal ENSO variability via an ocean teleconnection to the midlatitude Pacific is studied. This is done by analyzing the sensitivity of the equatorial stratification to midlatitude processes ...

Abstract: An experimental ENSO prediction system is presented, based on an ocean general circulation model (GCM) coupled to a statistical atmosphere and the adjoint method of 4D variational data assimilation. The adjoint method is ...

Abstract: One of the major factors determining the strength and extent of ENSO events is the instability state of the equatorial Pacific coupled ocean?atmosphere system and its seasonal variations. This study analyzes the coupled ...
