Аннотация: A solar-terrestrial relations were examined using millennium-scale paleoclimatic data from the Central Asia mountain region. The paleoclimatic data were based on non-varved lake sediments of the Teletskoye lake and temperature-sensitive long tree-ring width chronologies from the Altai region (Altai Mountains, South Siberia, Russia) in the late Holocene (2000 years). Also a solar-activity during late Holocene was used to analyze. Core of the bottom sediments from the Teletskoe lake (Altai Mountains) were investigated using scanning X-ray fluorescent analysis method with synchrotron radiation (spatial resolution is 0.1 mm). A method ensemble empirical mode decomposition (EEMD) was used to extract low-frequency variability from all presented paleoarchives. The results obtained for paleodata indicate palaeoclimatic oscillations in the range of the de Vries (Suess) (similar to 200-year) solar cycles through the late Holocene. Evidence of the influence of solar activity on global climatic processes and terrestrial ecosystems is discussed.
