Detailed bioclimate analysis of Banja Koviljača (Serbia)

Abstract

The study presents the results of detailed bioclimatological analysis of Banja Koviljaca. For the evaluation of bioclimate conditions significant for human health and activities, more than 100 indices have been developed. Indices based on human energy balance are proven to be the best for the evaluation of human thermal comfort. This paper analyses the variations and trends of the PET (Physiologically Equivalent Temperature) for Loznica meteorological station during the period 1961-2014. The fluctuations are analyzed for all seasons and annual values. In order to gain better insight into the variations of PET, seasonal and annual values of air temperature (Ta), relative humidity (RH), wind speed (v) and cloud cover (CC) were investigated. Trends in the annual and seasonal time series were determined using Mann Kendal trend test. Additionally, trends in bioclimatological extremes were determined. The results indicated that statistically significant increasing trends in annual and seasonal values of PET exist and that in the future the change in tourism season and recreation potential could change. The increase of these values could be connected to the increase in Ta, decrease in RH, v and CC.
