摘要：This paper deals with preliminary results of wider on-going scientific research about climate changes in Split Dalmatian County. Complete data base consisted of daily air temperature from January the 1st 1948 to December the 31st 2008 is taken into account but due to the nature of this article authors are focused only on the significance of air temperature oscillations in the last decade. For these reason standard deviation of air temperature is evaluated for the entire period of last sixty years and separately for each decade, each year and each month. The basic hypothesis that air temperature fluctuations from decade to decade have continuous upward trend is tested. The linear and polynomial air temperature oscillation trends for mean annual, mean five-year and mean ten-year air temperature are analyzed. The integral part of the research is the detailed comparative analysis of monthly air temperature oscillations for the last ten years.
