The signature of solar irradiance
variations on decadal-to-centennial climate variability is analyzed by means of statistical
analysis of long-term instrumental, historical and proxy data sets.
Solar variations associated with the Schwabe, Hale, and Gleissberg cycles
are detected by their spatial patterns in sea surface temperature
and seal level pressure.
Different statistical methods of instrumental and proxy data show that the mode related to solar irradiance
fluctuations on multidecadal timescales (Gleissberg cycle)
is distinct from
the Atlantic multidecadal mode associated to ocean circulation changes.
From this, one can infer the degree to which solar variability has contributed to long-term temperature variations
during the instrumental and pre-instrumental era.
