| Zusammenfassung |
| We present the first summer sunshine reconstruction from tree-ring data for
the western part of the Balkan Peninsula. Summer sunshine is tightly
connected with moisture stress in trees, because the moisture stress and
therefore the width of annual tree-rings is under the influence of the
direct and interactive effects of sunshine duration (temperature,
precipitation, cloud cover and evapotranspiration). The reconstruction is
based on a calibrated z-scored mean chronology, calculated from tree-ring
width measurements from 7 representative black pine (Pinus nigra Arnold) sites in
Bosnia and Herzegovina (BiH). A combined regression and scaling approach was
used for the reconstruction of the summer sunshine. We found a significant
negative correlation (r = −0.54, p < 0.0001) with mean June–July
sunshine hours from Osijek meteorological station (Croatia). The developed
model was used for reconstruction of summer sunshine for the time period
1660–2010. We identified extreme summer events and compared them to
available documentary historical sources of drought, volcanic eruptions and
other reconstructions from the broader region. All extreme summers with low
sunshine hours (1712, 1810, 1815, 1843, 1899 and 1966) are connected with
volcanic eruptions. |
