Solar Activity Cycles: Solar-Terrestrial Relations

Scientific paper

In order to understand the origin of the Suess wiggles, present in the tree ring 14C record, the authors have studied the thermoluminescence (TL) of a shallow-water Ionian Sea core, in an attempt to provide a record of an indicator responding to the solar output more promptly than 14C in tree rings. The spectral content of the TL and radiocarbon records is very similar; nevertheless, in addition to the 207-y Suess wave (A = 3.6%), the TL record shows the second harmonic (103.5 y; A = 2.4%), in phase with the envelope of the 11-y solar cycles. This result, obtained by different spectral methods, in particular by superposition of epochs and by singular spectrum analysis, strongly supports the solar origin of the 200-y Suess wiggles.
