Negative climatic extremes occur more frequently in the last decades. Since the Carpathian Basin is highly concerned in their impacts it is important to investigate prior events and estimate the response of the environment to them to get useful information for the future. In our work we selected a stand which is seriously affected by unfavorable summer conditions to examine what kind of fingerprint the negative extreme events have left. We investigated narrow rings and intra-annual density fluctuation to describe years with extreme events. Their stabilized frequency was tested against climatic and groundwater data, as well as against aridity index to determine climate-growth relationships using Pearson and Spearman's correlations. Our results show positive significant correspondence between summer precipitation and treering growth together with negative connection with summer temperature. The Spearman's correlation between stabilized frequency of intra-annual density fluctuations, narrow rings and climate data ended with significant relationship in summer. According to the comparison of intra-annual density fluctuation and narrow ring data with drought periods it can be said that narrow rings are better tool for the examination of negative extreme events in summer.

“…The concept that a clear climate signal can be found in the tree species growing under limiting conditions have been used in many reference dendroclimatological studies in recent decades, concerning the reconstruction of thermal (e.g., Jacoby and D'Arrigo 1989; Vaganov et al 1996;Rolland et al 2000;Cook et al 2003;Esper et al 2003;Barber et al 2004;Büntgen et al 2005;Gou et al 2008) and moisture conditions (e.g., Douglas 1914;Schulman 1956;Stockton and Meko 1975;Lara et al 2001;Cook et al 2004;Esper et al 2007). However, research on past climate changes based on the use of proxies are of great importance in other regions, too.…”

This study aims at investigating pre-instrumental tree-ring based winter thermal conditions from Upper Silesia, southern Poland. The Scots pine, pedunculate oak and sessile oak ring widths and the extreme index were used to reconstruct winter mean temperature back to A.D. 1770. The climate response analysis showed that the pine is the most sensitive to February (0.36) and March (0.41) temperature, the oaks were found to be sensitive to the previous December (0.27) and January (0.23) temperature. It was found out that the combination of temperature sensitive species and an additional extreme index in regression can improve the reconstruction, with an emphasis on more reliable reconstruction of extreme values. The elimination of variance reduction and precise reconstruction of actual values of temperature is possible by scaling. The obtained calibration/verification results suggest that, through the application of the long-term composite chronologies a detailed study of the climate variability in Upper Silesia in past centuries can be provided.
