Regional features of the radial growth of larch in north central Siberia according to millennial tree-ring chronologies

A 1138-year tree-ring chronology has been constructed for the region of the Bol’shoi Avam River (the Putoran Plateau). Its comparison with millennial chronologies for the Taimyr Peninsula and Mangazeya has shown that all these chronologies are fairly synchronous with respect to both high-frequency (annual) and low-frequency (long-term) components, although each has its specific regional features. The results of dendroclimatic analysis provide evidence for the prevailing influence of air temperature in July (compared to that in June) on the radial growth of larch in the middle reaches of the Bol’shoi Avam. Consistent long-term changes in radial tree increment (and in summer air temperature) in a large sector of the Subarctic over the past 1000 years have been revealed.
