Abstract
Manifestation of the 200-year solar cycle (de Vries cycle) in climatic changes (summer temperatures) has been investigated by analyzing the radial growth of long-lived (800–1200 yr) Juniperus turkestanica trees in Central Asia. Quasi-two-hundred-year variations in the radial growth of trees have been revealed, which correlate well (correlation coefficient reaches 0.94) with similar solar activity variations (Δ14C).
