Spatial and temporal evolution of drought conditions at various time scales in the Czech Republic during growing period

Original language description

This paper analyzes the characteristics of spatial evolution of the standardized precipitation evapotranspiration index (SPEI) at various time scales during the growing period (April-September) over the Czech Republic. The SPEI was calculated from monthly records of mean temperature and precipitation totals measured at a dense network of 184 climatological stations for the period 1961?2010. Using various lags, 1, 3, 6, 12, and 24 months. The drought at these time scales is relevant for agricultural, hydrological, and socio-economic impacts, respectively. The study refers to the warm season of the year (from April to September). The principal modes of variability of the SPEI calculated at these five time scales were identified by using the empirical orthogonal functions (EOF) analysis. The explained variance of the leading EOF ranges between 71 and 61% as the time scale for calculating the SPEI increases from 1 to 24 months. The explained variance of EOF2 and EOF3 ranges between 5 and 9
