Abstract

An analysis is made of global sea surface temperature (SST) data sets over the past 110 years to determine the principal patterns of climate variability on time scales longer than ENSO, and to relate these to likely dynamical processes. Taking 5-year running means, the most recent versions of the interpolated global data from the UK Hadley Centre and the US NOAA are analysed using singular value decomposition, and described as coherent global patterns that have a physical/dynamical basis. These patterns are: Global Warming, the Pacific Decadal Oscillation, the Atlantic Multi-decadal Oscillation and the Pacific Gyre Oscillation. Each of these patterns, as represented by SST, is described in b..
