Everyone should consider the possibility that for some indices, North Atlantic correlations (in correlation maps) are depressed by the North Atlantic's sensitivity (being the smaller northern basin surrounded by a lot of land / ice, resulting «higher continentality»), which gives it a propensity towards high amplitude oscillations, including decadal - timescale nonlinear trends.

Pacific Decadal Oscillation (PDO) Index and North Pacific Index (NPI).

Pacific Decadal Oscillation (PDO), a measure of the SSTs in the North Pacific that has a very strong correlation with the North Pacific Index (NPI) measure of the depth of the Aleutian Low.

The study by Macias & Johnson (2008) provides not only evidence for the link between decadal - scale changes in the teleconnection patterns (e.g. the Pacific Decadal Oscillation (PDO) index) and the increased fire frequency in the late twentieth century but also an explanation of why the pattern of fire variability and fire - climate relationships changes at different time scales from centennial / decadal to interannudecadal - scale changes in the teleconnection patterns (e.g. the Pacific Decadal Oscillation (PDO) index) and the increased fire frequency in the late twentieth century but also an explanation of why the pattern of fire variability and fire - climate relationships changes at different time scales from centennial / decadal to interannuDecadal Oscillation (PDO) index) and the increased fire frequency in the late twentieth century but also an explanation of why the pattern of fire variability and fire - climate relationships changes at different time scales from centennial / decadal to interannudecadal to interannual.....

It has been shown that the mass balance of these glaciers correlate with the PDO (Pacific Decadal Oscillation) and MEI (Mulitvariate ENSO index) particularly over a multi year period (McCabe and Fountain, 1995; Bitz and Batisti 1999; Hodge et al., 1998).

The variations are strongly correlated with the similar decadal fluctuations observed in the Atlantic Multidecadal Oscillation index, and less so with the El Nino Southern Oscillation index.
