## Abstract Maximum entropy spectrum analysis of 305 tree‐ring chronologies from North America yields evidence for two terms with periods 18.6 Β± 1.3 years (in 286 out of 305 series) and 10.5 Β± 0.5 years in 244 instances. Statistical tests show the terms to be significant at confidence levels of 99.
