European warm-season temperature and hydroclimate since 850 CE
The long-term relationship between temperature and hydroclimate has remained uncertain due to the short length of instrumental measurements and inconsistent results from climate model simulations. This lack of understanding is particularly critical with regard to projected drought and flood risks. Here we assess warm-season co-variability patterns between temperature and hydroclimate over Europe back to 850 CE using instrumental measurements, tre…
A 970-year-long summer temperature reconstruction from Rogen, west-central Sweden, based on blue intensity from tree rings
To assess past climate variability in west-central Scandinavia, a new 972-year-long temperature reconstruction, based on adjusted delta blue intensity (ΔBI adj ), was created. Presently, it is the longest blue intensity chronology in Fennoscandia and the third longest in the northern hemisphere. Measurements were obtained from 119 tree line Scots pine ( Pinus sylvestris L.) samples from Rogen, in the central Scandinavian Mountains, Sweden. Early …
Old World megadroughts and pluvials during the Common Era
An atlas of megadroughts in Europe and in the Mediterranean Basin during the Common Era provides insights into climate variability.
Using adjusted Blue Intensity data to attain high-quality summer temperature information
The inexpensive Blue Intensity proxy has been considered a complement or surrogate to maximum latewood density (MXD), but is associated with biases from differential staining between sapwood and heartwood and also between deadwood samples and living-wood samples that compromise centennial-scale information. Here, we show that, with some minor adjustments, ΔBlue Intensity (ΔBI) is comparable with MXD or ΔDensity (Δ = the difference or contrast bet…
Reconstruction of a regional drought index in southern Sweden since AD 1750
We used a network of eight pedunculate oak ( Quercus robur L.) sites ( n trees = 70) and one Scots pine ( Pinus sylvestris L.) site ( n trees = 53) to develop drought-sensitive master chronologies for the two areas in southern Scandinavia: a SW-area centred on 57°N 12.7°E and a NE-area centred on 58.8°N 18.2°E. The ratio of actual to equilibrium evapotranspiration (AET/EET) was used as a measure of drought during the growing season defined as the…
