| Abstract | Climate change is one of the most important challenges of the modern era. The aims of this study were assessed (1) the climatological analysis for two periods: far-past (1979-1998) and near past (1999-2018) over the United Arab Emirates, (2) statistical evaluation of ERA5-reanalysis dataset against climatic historical reference period, and (3) investigate heatwave indices and their characteristics over the UAE from 1979 to 2050 using CORDEX model at RCP4.5 scenarios. Results showed that the effects of climatic changes appeared to be clear on the temperature and precipitation within the UAE. Temperature increased by 1.15 ?C between 1979 and 2018, and therefore the annual average rainfall decreased by -81.5 mm within the same time period. Slight difference in temperature between observation and ERA5 clearly shown a strong positive correlation, on the contrary, precipitation is shown significantly high error values because of the plurality of climate and its variability between tropical semi-arid and desert climate. The number, frequency, duration, magnitude and amplitude of heat waves accelerates from the beginning of the study period in 1979 and continues to increase until the end of study at year 2050 in UAE. By studying thermal comfort, it was found that most of the population suffers from thermal discomfort and reaches severe stress in July and August. Two main types of heat wave impacts have so far been underlined: divorce cases and road accidents. However, this list is not exhaustive, as wider social impacts may occur during heat wave events. |
