This paper is devoted to detection of some expected changes in the climatological regime (means, variability, frequency distribution) at selected elements due to climate change. Very reliable time series of daily data (air temperature and relative humidity since 1951) measured by the meteorological stations at Hurbanovo, 115 m a.s.l., SW Slovakia, Poprad, 695 m a.sl., at the foot of the High Tatras mountains and Lomnický štít, 2635 m a.s.l., the 3rd highest peak in Slovakia have been utilized. More over the daily aerological data measured at the Poprad-Gánovce Observatory since 1961 (850 hPa) were elaborated for comparisons with those obtained by ground measurements. Some results are compared also with those designed as climate change scenarios for Slovakia based on the modified CGCM2 GCM outputs. The results showed very significant increase in temperature and decrease in relative humidity
in the April to August season after 1990. Only selected results are presented in this extended abstract
