Drought evolution at various time scales in the lowland regions and their impact on vegetable crops in the Czech Republic

Popis výsledku v původním jazyce

Two multi-scalar drought indices, the Standardized Precipitation Index (SPI) and the Standardized Precipitation?Evapotranspiration Index (SPEI), were used to study secular drought evolution from 1901 to 2010 in the lowland regions of the Czech Republic.To assess the temporal patterns of droughts as multi-scalar events, the SPEI and SPI were calculated for short-term (1?2 months), medium-term (3?12 months) and long-term droughts (13?24 months). In this study, daily and monthly potential evapotranspiration was integrated to estimate the evaporative power of the atmosphere and to explain its effect on drought conditions in the Czech Republic. For the lowland regions in the Czech Republic, long winter droughts occurred frequently at the beginning of the 20th century, while spring and summer droughts prevailed toward the end of the century. The mean durations of the drought episodes calculated from both indices were the same in the short time scales, between 2.2 and 2.5 months, whereas the
