    Projections of future change of climatology and extreme weather events in the Mediterranean Basin, by the HIRHAM5 regional climate model
    (Marmara Üniversitesi, 2022-03-30) Öztürk, Tuğba
    In this study, changes in temperature and precipitation climatology and extreme weather events over the Mediterranean Basin including Turkey were investigated using HIRHAM5 driven by global climate models such as EC-EARTH, HadGEM2-ES, and NorESM1-M for 2011-2100 compared to 1971-2000. RCP4.5 and RCP8.5 scenario outputs of global climate models were used as forcing data. Daily mean temperature and precipitation variables are used to compute extreme indices. Extreme indices were calculated for the period of 2071-2100 compared to the reference period. According to the results, the severity of temperature- and precipitation-based indices will be expected to increase throughout the century with increasing radiative forcing. Minimum of minimum temperatures will increase more pronounced over the northern Mediterranean, which is referred to as climate change hot spots, whereas the increase in a maximum of maximum temperatures is moderate over land areas. A decrease in total wet-day precipitation is expected while the number of dry days is expected to increase. Therefore, the Mediterranean Basin and Turkey will have warmer and drier conditions compared to present climate conditions.
