Abstract
In the Hungarian capital city, Budapest, no detailed human thermal comfort examinations have been performed until now despite the fact that the analysis of urban climate from a human comfort point of view is extremely timely. Hie objective of the present study is to evaluate the differences and changes of the thermal comfort conditions in the last half century based on the measurements of two meteorological stations located in different environments: one in the central urban area (Local Climate Zone 2 - 'compact midrise') and the other in the suburbs (between Local Climate Zones 6 - 'open lowrise' and A - 'dense trees'). The thermal comfort was quantified using a popular bioclimate index, the Physiologically Equivalent Temperature (PET) for four characteristic times of the day: 6, 12, 18 and 24 UTC in the period of 1961-2010. Then the thermal comfort differences between the stations according to three climatic normal periods (1961-1990, 1971-2000 and 1981- 2010), and the tendencies detected among the periods were also analyzed. For the last decade, 2001-2010, more detailed hourly-resolution investigations were carried out. According to the results, the annual and seasonal averages of PET are higher in the central area in each climate normal period and at all dates; furthermore the PET averages increase during the consecutive 30-year periods. The results proved that warm stress has become more frequent; however, the cold heat load decreased in both examined area. Investigating the hourly data, in terms of the whole ten-year period, a higher ratio of hot stress and less cold stress can be observed in the central area.
