abstract = "In this paper, we sought to investigate the spatial and temporal
variability of the global sea surface temperature in the 1884-2014
period, through wavelet analysis. Results for tropical,
subtropical, and extratropical areas indicate important
oscillations in the 1-12-month and 1-2-, 2-4-, 4-8-, and 8-12-year
spectral ranges, as obtained in other studies which used regional
mean SST values instead of global gridpoint data with 2.5(o)
resolution, as used in this study. The intraseasonal (1-12months)
and interannual (1-2years) oscillations are much more evident in
the tropical latitudes. On the other hand, lower frequency
oscillations (2-4, 4-8, and 8-12years) are more dominant away from
tropical regions. The faster oscillation scale (1-12-month and
1-2- and 2-4-year spectral ranges) SST variance presents negative
trends throughout the entire period, while the values associated
with the slower oscillation scales (4-8- and 8-12-year spectral
ranges) present increasing trends. The reversal of trends for
distinct SST spectral ranges over the whole period suggests energy
exchanges between distinct oscillatory phenomena. In addition, the
energy increase of slower frequencies suggests the prolonged
settlement of low-frequency climatic patterns in the future,
providing more inertial climatic patterns. The strongest
diminishing values of SST variance associated with the higher
frequency oscillations were observed in the Atlantic oceanic
basins. The strongest increasing values for the lower
oscillations, mainly related to the 2-4- and 4-8-year spectral
ranges, were observed in the Pacific basins. In general, the
Pacific basins are closely correlated with the global mean
(0.55r0.92), compared with the Atlantic (0.31r0.75) and Indian
(0.12r0.56) basins.",
