Warunki klimatyczne na Górnym Śląsku w okresie 1645-2009 na podstawie analizy lat wskaźnikowych Abies alba, Pinus sylvestris, Larix decidua, Fagus sylvatica i Quercus spp.

Abstract

Pointer years were identified for tree-ring chronologies of silver fir, Scots pine, european larch, common beech, sessile oak, pedunculate oak, nor-thern red oak and then related to weather records (documentary and instrumental data) during the 17th- 20th centuries. The strongest pointer years occurred throughout a range of taxa and were compared with other regions. Exceptional years (dry, wet and frosty) in Upper Silesia particularly often appear in the periods: 1645-1720, 1834-1876, 1940-1976.
