The Mid-1970s Climate Shift in the Pacific and the Relative Roles of Forced versus Inherent Decadal Variability
A significant shift from cooler to warmer tropical Pacific sea surface temperatures (SSTs), part of a pattern of basinwide SST anomalies involved with a transition to the positive phase of the Interdecadal Pacific Oscillation (IPO), occurred in the mid-1970s with effects that extended globally. One view is that this change was entirely natural and was a product of internally generated decadal v...
متن کاملDecadal to multidecadal variability and the climate change background
[1] Three prominent quasi-global patterns of variability and change are observed using the Met Office’s sea surface temperature (SST) analysis and almost independent night marine air temperature analysis. The first is a global warming signal that is very highly correlated with global mean SST. The second is a decadal to multidecadal fluctuation with some geographical similarity to the El Niño–S...
متن کاملInterdecadal-Decadal Climate Variability from Multi-Coral Oxygen Isotope Records in the South Pacific Convergence Zone Region Since 1650AD
[1] In the South Pacific, interdecadal-decadal oceanic and atmospheric variability, referred to as the Interdecadal Pacific Oscillation (IPO), is most pronounced in the South Pacific Convergence Zone (SPCZ) salinity front region. Here we have used annual average oxygen isotope (dO) time series from five coral cores collected from Fiji and Tonga in this region to construct a Fiji-Tonga Interdeca...
متن کاملThe Pacific Decadal Oscillation and Pacific Salmon Production
Retrospective analyses of Pacific Basin climate records highlight the existence of a pan-Pacific interdecadal climate oscillation. We find strong evidence for coherent patterns of interdecadal variability in Pacific winds, sea level pressures, and upper ocean temperatures. Collectively, the ocean-atmosphere pattern of variability has been labeled the “Pacific Decadal Oscillation”, or PDO. An in...
متن کاملNorth Pacific Decadal Climate Variability since 1661
Climate in the North Pacific and North American sectors has experienced interdecadal shifts during the twentieth century. A network of recently developed tree-ring chronologies for Southern and Baja California extends the instrumental record and reveals decadal-scale variability back to 1661. The Pacific decadal oscillation (PDO) is closely matched by the dominant mode of tree-ring variability ...
