The Atlantic Multidecadal Oscillation (AMO) or Variability (AMV) is a mode of low frequency (i.e., decadal to multidecadal) climate variability centered over the North Atlantic basin.

More recent work is identifying climate shifts working through the El Niño - Southern Oscillation (ENSO), Atlantic Multidecadal Oscillation (AMO), Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO), Southern and Northern Annular Modes (SAM and NAM), Artic Oscillation (AO), Indian Ocean Dipole (IOD), North Pacific Oscillation (NPO) and other measures of ocean and atmospheric states.

In 2014 climate scientists published a peer - reviewed paper (Johnstone 2014) suggesting that climate change along the coast of North America could be best explained by natural cycles of Pacific Decadal Oscillation (PDO) due to its affects on sea surface temperatures in the eastern Pacific.

We do know that ocean basins produce this oscillatory behavior — the El Nino / Southern Oscillation, the Arctic Oscillation, the Pacific Decadal Oscialltion, the NAO, the Madden - Julian Oscillation (Indian Ocean), but they seem to have a bit of a random component, their forcing mechanisms are poorly understood, their «phase changes» appear impossible to predict very far in advance, and they must also be sensitive to the overall climate warming.

The long time range of this dataset allows scientists to examine better long time scale climate processes such as the Pacific Decadal Oscillation and the Atlantic Multidecadal Oscillation as well as looking at the dynamics of historical climate and weather events.

Interactions between externally - forced climate signals from sunspot peaks and the internally - generated Pacific Decadal and North Atlantic Oscillations «When the PDO is in phase with the 11 year sunspot cycle there are positive SLP anomalies in the Gulf of Alaska, nearly no anomalous zonal SLP gradient across the equatorial Pacific, and a mix of small positive and negative SST anomalies there.

Additional interests include the effects of the Pacific Ocean on the climate of British Columbia and how those effects are transmitted through such phenomena as El Niño / Southern Oscillation, the Pacific Decadal Oscillation, and the atmospheric teleconnections they induce.

Known climate oscillations resulting from these interactions, include the Pacific decadal oscillation, North Atlantic oscillation, and Arctic oscillation.

The models exhibit large variations in the rate of warming from year to year and over a decade, owing to climate variations such as ENSO, the Atlantic Multi-Decadal Oscillation and Pacific Decadal Oscillation.
