Climate change that has occurred at the end of the last and at the beginning
of this century, among other things, has a certain impact on forests as well.
For the territory of Eastern Serbia, for two periods of climate observations,
the reference period 1961-1990 and the period 1991-2012, a comparative
analysis of the following climatic elements was done: air temperature, amount
of precipitation and relative humidity of air. Calculations were performed on
the basis of collected and systematized data from 11 meteorological stations
(6 synoptic/main climatological and 5 regular climatological) that were part
of the Republic Hydrometeorological Service, situated in the area of Eastern
Serbia. Analysis of the anomalies of air temperature and precipitation as
indicators of climate change for the period 1991-2012 compared to the
reference period 1961-1990 was done separately for each of the four seasons
(winter, spring, summer, autumn) and summarized for each period. The results
of the comparative analysis show that in the period 1991-2012 compared to the
reference period 1961-1990, there was an increase in the average annual air
temperature, as well as the increase in the average air temperature for all
four seasons, and a decrease in the average annual amounts of precipitation
and the decrease in the relative humidity of air.
