Yayın Simulating the climatology of extreme events for the Central Asia domain using the RegCM 4.0 regional climate model(Springer-Verlag Berlin Heidelberg, 2012-01-01) Altınsoy, Hamza; Öztürk, Tuğba; Türkeş, Murat; Kurnaz, Mehmet LeventIn this work, future changes in the frequency of the seasonal extreme climate events such as number, frequency, duration and intensity of heat waves (5 consecutive temperature days above the maximum temperature calendar day 90th percentiles, number of days per year that is above the same percentiles and greatest number of consecutive days above these percentiles) for the period of 2071–2100 over Central Asia (18.56 –70.13 East and 7.28 –142.4 North) with respect to the present period of 1971–2000 were studied in detail. Regional Climate Model RegCM 4.0 of Abdus Salam International Center for Theoretical Physics (ICTP) with ECHAM5 forcing data was used for hindcast and forecast projection. This region will very likely be affected by heat waves in winter and spring seasons and heat wave frequency, intensity and duration will increase significantly over the Arabian Peninsula in summer. On the other hand, cold spells will not change as much as heat waves over the region in all seasons.Yayın Climate change versus 'security and peace' in the Mediterranean macroclimate region: are they correlated?(Coventry University, 2011-10-28) Türkeş, Murat; Öztürk, Tuğba; Altınsoy, HamzaClimate 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.
