Abstract
Annual average summer temperature variations can be reconstructed using
dendrochronology methods (analysis of tree rings). We perform spectral
analysis of temperature series reconstructed for the last 3000-4000
years and for various geographical locations both in the northern and
southern hemispheres. Spectral properties of these data series were
calculated using wavelet decomposition and methods of higher order
spectral analysis. The obtained spectral features are compared with the
known solar periodicities. No evident correlation between the
reconstruted temperature and the 11 year solar cycle is found.
