Tree-ring isotope records of tropical cyclone activity.
The destruction wrought by North Atlantic hurricanes in 2004 and 2005 dramatically emphasizes the need for better understanding of tropical cyclone activity apart from the records provided by meteorological data and historical documentation. We present a 220-year record of oxygen isotope values of alpha-cellulose in longleaf pine tree rings that preserves anomalously low isotope values in the l...
متن کاملBridging the Gaps in Tree-ring Records: Creating a High-resolution Dendrochronological Network for Southeastern Europe
Dendrochronological research in North-Central Europe and the East Mediterranean has produced networks of long regional oak (Quercus sp.) reference chronologies that have been instrumental in dating, provenancing, and paleoclimate research applications. However, until now these two important tree-ring networks have not been successfully linked. Oak forests and historical/archaeological sites in ...
متن کاملMillennia-long Tree-ring Chronologies as Records of Climate Variability in Finland
There have been great advances in the field of dendroclimatological research during the past decades. Tree-ring data have been used to derive various climate variables for certain localities and for larger regions. Characteristics of tree-rings provide measurements which can be used as records of climate variability prior to any instrumental weather observations. This is how dendroclimatology c...
متن کاملA forward modeling approach to paleoclimatic interpretation of tree-ring data
[1] We investigate the interpretation of tree-ring data using the Vaganov-Shashkin forward model of tree-ring formation. This model is derived from principles of conifer wood growth, and explicitly incorporates a nonlinear daily timescale model of the multivariate environmental controls on tree-ring growth. The model results are shown to be robust with respect to primary moisture and temperatur...
متن کاملA watershed modeling approach to streamflow reconstruction from tree-ring records
Insight into long-term changes of streamflow is critical for addressing implications of global warming for sustainable water management. To date, dendrohydrologists have employed sophisticated regression techniques to extend runoff records, but this empirical approach cannot directly test the influence of watershed factors that alter streamflow independently of climate. We designed a mechanisti...
