Minimum air temperatures going to extremes in Brașov city (Romania)

Brașov is the largest city in the Romanian Carpathians, being located inside the largest low-lying area in the country and exposed to western climatic influences, with well-defined local features, especially in the cold season, when many thermal extremes may occur. The main objective of this study was to analyze the minimum air temperatures and highlight their extreme values over the 1980-2015 period. The climatic data were collected from the Brașov-Ghimbav meteorological station and a set of specific indices, generically called as indices of extremes and climate change by the WMO’s Expert Team on Climate Change Detection and Indices (ETCCDI), were subsequently calculated. The resulting quantitative assessments of minimum air-temperature variations in the above mentioned area has also proved that they can be useful tools in calculating other derived technical parameters which may be relevant for the design and onset of heating or cooling installations, in order to maintain a comfortable indoor climate in residential buildings
