Long-term comprehensive agro-climatic evaluation

Original language description

In the last two decades a vegetation season in the Czech Republic (Central Europe) was prolonged about 15 to 25 days. It causes (i) an increasing risk of winter crops damage by frosts in the beginning of vegetation, (ii) a risk of occurrence of the days with the temperature below 0 oC without a snow cover (problems with overwintering), (iii) overgrowing plants during the autumn. A snow cover and its effect on agriculture have been generally underestimated by impacts studies of the climate change. An occurrence of the days with temperature below 0 oC without a snow cover was evaluated for the periods of 1961-1990, 1981-2010 and 1991-2010. Basic databases included daily data from 73 climatological station regularly distributed in the whole Czech Republic. Categories of the days with temperature below 0 oC without a snow cover were defined as the episode with snow cover lower than 5 cm and with minimum air temperature below -5 oC, -10 oC and -15 oC. Spatial evaluation was carried out for two seasons 1961-1990 and 1981-2010. Their comparison showed apparent decrease of the days with the temperature below 0 oC without a snow cover in the second season in majority of areas. In connection with risks of plants overgrowing of winter crops during the autumn, "autumn vegetation days" (AVD) for winter crops were defined (i.e. the days with maximum air temperature in 2 m exceeded 5 oC and precipitations were simultaneously normal or above normal). Number of AVD were analysed for period 15.8.-31.12. for each year in period 1961-2010. Average AVD values were 36.22; 35.26; 34.42; 40.95 a 37.27 for decade period. Increasing of AVD during two last decades was found.
