Multi-scalar indices of drought in intensively farmed regions of the Czech Republic
Original language description
Indices related to specific timescales are useful for monitoring and management of droughts. We compare the multi-scalar standardized precipitation index (SPI) and standardized precipitation-evapotranspiration index (SPEI) across the Czech Republic. Thedifferent timescales provided by the two indices can be related to different kinds of drought and their agricultural, hydrological and socio-economic impacts. Short timescales pick out variations of soil water that affect crops; water resources held in reservoirs are related to longer timescales. Data recorded since 1901 were examined to identify differences between the effects of precipitation and evapotranspiration on drought frequency. SPEI and SPI gave different indications during decades with cooldry summers (the first two decades of the twentieth century), the hottest summers (the end of the twentieth century), warm, wet springs (at the beginning of the twentieth century) and years with a big water deficit (1947, 2003, 1994, 1983
