Description
  • In the present study, the Standardized Precipitation Evapotranspiration Index (SPEI) was adopted to assess temporal evolution of wet and dry months during growing season (April to September) in the Czech Republic based on a dense network of 184 climatological stations for the period 1961–2010. The SPEI were calculated with various lags, 1, 3, 6, 12 and 24 months because the drought at these time scales is relevant for agricultural, hydrological and socio-economic impact, respectively. To assess the temporal evolution of dry and wet conditions during the growing season, first, the monthly time series of the SPEI for the months April to September were averaged at each station for each SPEI accumulation period (1, 3, 6, 12 and 24 months, respectively). Then, these SPEI time series were averaged over all 184 stations to get a time series of drought index at country level. The temporal evolution of the SPEI with one month lag represents the year by year moisture characteristic of the current growing season. In this respect, at country level, during the second half of the 20th century and the first decade of 21st century, the hierarchy of the driest years during the growing season was 2003, followed by 1992, 2000, 1983, 1982, 1976, 2009 and 1999. On the other hand, the wettest years during the growing seasons were 1965, 2010, 1977, 1996, 1966, 2001, 1972, 1980 and 1995.
