    Climate change has been and increasingly will be a major threat to the ski tourism industry whose survival is highly dependent on existence of snow cover of sufficient depth and duration. The common knowledge requires that in order for a ski resort to be viable, it has to perform operations for at least 100 days in seven out of ten winters. For this matter, it is now even more usual for the ski resorts to adapt to this issue by technical snowmaking. In this study, projected future changes for the period of 2010-2040, 2040-2070, and 2070-2100 in air temperature, relative humidity, and snow depth climatology and variability with respect to the control period of 1970-2000 were assessed for the domain of a major ski resort in Turkey. Regional Climate Model (RegCM4.3.5) of ICTP (International Centre for Theoretical Physics) was used for projections of future and present climate conditions. HadGEM2 global climate model of the Met Office Hadley Centre, MPI-ESM-MR of the Max Planck Institute for Meteorology, GFDL-ESM2M of the National Oceanic and Atmospheric Administration Geophysical Fluid Dynamics Laboratory were downscaled to 10 km for the resort and its surrounding region. Both the projections and the downscaling were realized according to the RCP4.5 and the RCP8.5 emission scenarios of the IPCC. The outputs on snow depth were used for a count of the changes on snow cover duration sufficient for skiing actitivies, signaling natural snow-reliability, whereas the outputs on air temperature and relative humidity were utilized for determination of wet-bulb temperatures. The latter measure was used to interpret the changes in the snowmaking capacity, in other words; technical snow-reliability, of the resort.

    Climate change versus 'security and peace' in the Mediterranean macroclimate region: are they correlated?
    (Coventry University, 2011-10-28) Türkeş, Murat; Öztürk, Tuğba; Altınsoy, Hamza
    Climate change, whether its global or regional scale, is one of the most significant and far-reaching challenges that the human societies living in the Earth’s surface have faced in the 21st century as it was in the 20th century. Consequently, the aim of this study is to scientifically assess impacts of the global and regional climate changes and variability including decreased precipitation amounts (drying) and increased air temperatures (warming) that would very likely cause to increase frequencies, durations and intensities of the drought events in the Mediterranean basin and Turkey, and associated problems and consequences with respect to the global, regional and national peace, prosperity and security issues and concerns.

    Future projections of air temperature and precipitation for the CORDEX-MENA domain by using RegCM4.3.5
    (European Geosciences Union (EGU), 2015-04-17) Öztürk, Tuğba; Turp, Mustafa Tufan; Türkeş, Murat; Kurnaz, Mehmet Levent
    In this study, the projected changes for the periods of 2016 – 2035, 2046 – 2065, and 2081 – 2100 in the seasonal averages of air temperature and precipitation variables with respect to the reference period of 1981 - 2000 were examined for the Middle East and North Africa region. In this context, Regional Climate Model (RegCM4.3.5) of ICTP (International Centre for Theoretical Physics) was run by using two different global climate models. MPIESM-MR global climate model of the Max Planck Institute for Meteorology and HadGEM2 of the Met Office Hadley Centre were dynamically downscaled to 50 km for the CORDEX-MENA domain. The projections were realized according to the RCP4.5 and the RCP8.5 emission scenarios of the IPCC (Intergovernmental Panel of Climate Change).
