Air temperature series of three weather stations in Brno from different parts of the period 1891 - 1995 were homogenized with the use of Maronna-Yohai and Alexandersson tests. Temperature series of the stations Vienna-Hohe Warte and Hurbanovo were used as reference homogeneous ones. One compiled air temperature series was made for Brno in the above mentioned period from the homogenized series. Long-term changes and periodicity of monthly, seasonal, and annual values of air temperature were examined (smoothing with the Gaussian filter, linear trend, autocorrelation analysis and spectral analysis Blackman and Tukey). The analyses confirmed warming trends in all months ranging from 0.04 (October) to 0.15 (August) °C per 10 years.
