Documentary and instrumental-based drought indices for the Czech Lands back to AD 1501

Popis výsledku v původním jazyce

This study addresses the reconstruction of 4 slightly different drought indices in thenCzech Lands (now the Czech Republic) back to 1501 AD. Reconstructed monthly temperatures fornCentral Europe that are representative for the Czech territory, together with reconstructed seasonalnprecipitation totals from the same area, are used to calculate monthly, seasonal and annualndrought indices (SPI, SPEI, Z-index, and scPDSI). The resulting time series reflect interannual tonmulti-decadal drought variability. The driest episodes cluster around the beginning and end of then18th century, while 1540 emerges as a particularly dry extreme year. The temperature-driven drynessnof the past 3 decades is well captured by SPEI, Z-index and scPDSI, whereas precipitationntotals show no significant trend during this period (as reflected in SPI). Data and methodologicalnuncertainty associated with Czech drought indices, as well as their position in a greater Europeanncontext, are critically outlined. Comparison with fir tree-rings from southern Moravia and a spatialnsubset of the Old World Drought Atlas’ (OWDA) reveals statistically significant correlation coefficients,nof around 0.40 and 0.50, respectively. This study introduces a new documentary-basednapproach for the robust extension of standardised drought indices back into pre-instrumentalntimes, which we also believe has great potential in other parts of the world where high-resolutionnpaleoclimatic insight remains limited.
