ABSTRACT
Changes in daily extremes events is one of the most important topic in climate literature and many studies have been conducted so far at local or regional scale worldwide. For the Romanian territory, only little research on this issue was done. In this article, the Carpathian and intra-Carpathians regions of Romania were considered. This study is focused on analyzing the trends of daily extreme temperature indices at a regional scale over a period of 50 years: 1961–2010. Data sets of daily minimum and maximum temperature recorded in 10 weather stations were analyzed. The main goal was to find changes in daily extreme temperatures by using a set of 9 indices adopted from the core indices developed by ETCCDMI with appropriate modifications to suit to the analyzed territory. The main results suggest that the climate has become warmer during the last decades. Trends of extreme temperature indices at the regional scale of Carpathians and intra-Carpathians areas are increasing for most of the indices calculated. It has been identified that both extreme daily maximum and minimum temperatures indices have increased in the analyzed areas. For all the indices related to hot temperature most trends are statistically significant.
