Abstract

The work presents two new 1000-year tree-ring chronologies: Tara (AD 795-2011, the South Chui Range) and Koksu (AD 588-2011, the Katun Range). The calculation of the response function shows that the dominating factor affecting the radial growth of the tree-ring chronology Koksu is June and July temperatures and for Tara it is June temperature. The strong correlation between Koksu chronology and records of meteorological stations placed in the Northern Mongolia and China at a distance of 300 or more kilometers from the sites of sample collection illustrates that the chronology reflects summer temperature changes at least on a regional scale. At the same time Tara chronology is weakly sensitive to changes in summer temperatures and may be used for dating of geomorphologic, historical and climatic events. The analysis of abnormal structures and missing rings detected on the samples revealed the dates of extreme events for each chronology
