Long tree-ring records in Central Europe and their climatologic significance

Submitted bachelor thesis is considered with use of tree-ring dates for reconstruction of climatic conditions in the past. There is a review of some most important long tree-ring reconstructions worldwide and a review of long central-european tree-ring reconstructions in the tesis. Central European dendroclimatic reconstructions longer than 250 years were compared to each other in accordance with their length, statistical strenghtness and ability to preserve high- and/or low-frequency climatic signal. Resulting reconstructions were also compared in this bachelor thesis. Greater variability among temperature reconstructions is evident contrary to conformity of hydroclimatic reconstructions. Localisation of Central European chronologies, possible causes of differencies among reconstructions and comparisons with other proxy data were discussed. Keywords: tree-rings, dendrochronology, dendroclimatology, climat
