Roxana Simona BOCANCEA
ABSTRACT: Among the weather events generated by extreme temperatures, heat waves are some of the most harmful which in the recent years has obviously increased the nature of climate risk. The main reason why we decided to conduct such a research is due to the profound socio-economic impact of heat waves in urban areas. The aims of this study were to analyze heat waves at Iasi meteorological station based on the daily maximum temperature during 56-year period (1961-2016). The frequency and duration were analyzed by applying the 95th percentile method and choosing the length of an event of minimum three consecutive days. The results were showing that the most frequent heat waves are those lasting 3 and 4 days, but regarding the duration, the longest heat waves were considered during the summer of 2007, lasting 10 days at Iasi meteorological station. The main result is that the frequency trend is significantly increasing.
