摘要：

Spectral comparison of the Hulu Cave, GRIP, and GISP2 delta O-18 records suggests that the single dominant period centered on 1470 yr in the GISP2 spectrum, the so-called '1500-yr cycle', is an artifact of the age model. The Th-230-dated Hulu Cave record indicates a millennial-band spectrum with a weak spectral peak near this period flanked by two stronger peaks centered on 1667 and 1190-yr, similar to the GRIP delta O-18 record. All three millennial-band cycles may derive from heterodynes of centennial-band solar cycles as observed in the Holocene record of atmospheric C-14 production. This suggests a link between centennial-scale solar variability and abrupt climate change at the millennial time scale. (c) 2004 Elsevier Ltd. All rights reserved.
