Quasi-decadal and inter-decadal climate fluctuations in the Pacific Ocean from a CGCM
International audience Diagnostic analyses in the Pacific, have revealed distinct quasi-decadal (QD) and inter-decadal (ID) climate fluctuations with coherent varying patterns of sea surface temperature (SST) and sea level pressure (SLP) anomalies. From a 200-year CGCM simulation, distinct low-frequ...
