Drought reconstruction based on grape harvest dates for the Czech Lands, 14992012
Popis výsledku v původním jazyce
The timing of maturity of grapes depends on the weather conditions during thengrowing season. This study relies on the dependence of harvest dates on the air temperature andndry/wet conditions. Recorded observations show that increases in air temperature and dryness arenassociated with earlier grape harvests. Documentary data of grape harvests from the Bohemiannwine-growing region (mainly northwest of Prague) were combined with mean Standardized PrecipitationnEvapotranspiration Index (SPEI) series starting in 1841 and ordinary least squarenregression with subsequent scaling to reconstruct the mean SPEI values for this area for April tonAugust from 1499 to 2012. The reconstructed SPEI series explains 75% of the drought variabilitynsince 1841. All dry years that were detected by the reconstructed AprilAugust SPEI values correlatenwell with years of excellent and good red wine of vintage quality for 14991840. A comparisonnof the reconstructed series with other SPEI reconstructions from the Czech Lands (the recentnCzech Republic) based on documentary and instrumental data shows good agreement. Thenresults demonstrate that grape harvest series may be used as a proxy for drought reconstructionnin the central European region.
