DETECTION OF URBAN SUMMER WARMING IN TEMPORAL CHANGE OF HEAT STRESS-RELATED INDICES IN THE ROMANIAN PLAIN REGION
Journal Title: Revue Roumaine de Géographie/Romanian Journal of Geography - Year 2013, Vol 57, Issue 2
Abstract
The study presents evidence of an increased frequency of hot temperatures and the corresponding urban heat stress in southern Romania, in response to the observed changes in the upper tails of the probability density function distribution of summer daily maximum temperatures, since the mid 1980s. This paper discusses the seasonal variability trends of some relevant heat stress-related indices, yet not directly comparable by their definitions, derived from daily minimum and maximum temperature in situ measurements. The analyses aimed also at assessing the change in the frequency, persistence and magnitude of heat stress at six weather stations located in the Romanian Plain Region, found representative for urban and suburban thermal conditions. The study suggests that, during the last decades, the cities in the Romanian Plain Region experienced a significant increase of heat stress under a higher occurrence probability of hot summer days and nights and prolonged heat waves, corrensponding to a growing need for cooling in summer, as well as in early autumn and late spring months, in response to the recent seasonal trends in minimum and maximum temperatures
