Sentences with phrase «decadal oceanic variability»

Not exact matches

Spectral analyses suggested that the reconstructed annual mean temperature variation may be related to large - scale atmospheric — oceanic variability such as the solar activity, Pacific Decadal Oscillation (PDO) and El Niño — Southern Oscillation (ENSO).

The paper... offers a useful framework for which decadal variations in the global (or northern hemisphere) may be explained via large scale modes of oceanic variability.

Together the oceanic upwelling in the north and south Pacific and the movement of atmospheric mass from and to the poles provide almost all of the decadal variability in Earth's climate.

Natural factors such as the Sun (84 papers), multi-decadal oceanic - atmospheric oscillations such as the NAO, AMO / PDO, ENSO (31 papers), decadal - scale cloud cover variations, and internal variability in general have exerted a significant influence on weather and climate changes during both the past and present.

Given these and other misrepresentations of natural oceanic variability on decadal scales (e.g., Zhang and McPhaden 2006), a role for natural causes of at least some of the recent oceanic warming should not be ruled out.»

Increasing attention is being paid to IPCC misrepresentations of natural oceanic variability on decadal scales (Compo and Sardeshmukh 2009): «Several recent studies suggest that the observed SST variability may be misrepresented in the coupled models used in preparing the IPCC's Fourth Assessment Report, with substantial errors on interannual and decadal scales (e.g., Shukla et al. 2006, DelSole, 2006; Newman 2007; Newman et al. 2008).
