    Assessment of projected changes in air temperature and precipitation over the Mediterranean region via multimodel ensemble mean of CMIP5 models
    (TÜDAV, 2015) Turp, M. Tufan; Öztürk, Tuğba; Türkeş, Murat; Kurnaz, M. Levent
    A multi-model ensemble mean approach was followed in order to investigate the projected changes in near surface air temperatures and precipitation total over the Mediterranean region. Among sixty seven different models of thirty modeling groups all around the world participating in the World Climate Research Programme (WCRP) Coupled Model Intercomparison Project (CMIP5), fourteen models were used. In this respect, we focused on two distinct scenarios (i.e. RCP4.5 and RCP8.5) for three different future periods (i.e. 2016-2035, 2046-2065 and 2081-2100) to examine accurately the foreseen changes in two fundamental climate variables (near surface air temperature and precipitation total) for the Mediterranean region.

    Impacts of climate change on precipitation climatology and variability in Turkey
    (Springer International Publishing Ag, 2020) Türkeş, Murat; Turp, M. Tufan; An, Nazan; Öztürk, Tuğba; Kurnaz, Mehmet Levent
    In this chapter, changes in seasonal precipitation climatology, extreme weather conditions, and aridity conditions of Turkey are evaluated for the period of 2021-2050 with respect to the reference period of 1971-2000 by using regional climate model simulations. Projections of future climate conditions are modeled by forcing Regional Climate Model, RegCM4.4 of the International Centre for Theoretical Physics (ICTP) with MPI-ESM-MR global climate model of the Max Planck Institute for Meteorology. The outputs of MPI-ESM-MR are used to generate 10 km resolution data by the double nesting method under both RCP4.5 and RCP8.5 emission scenarios. The seasonal time-scale performance of RegCM4.4 in reproducing the observed climatology over Turkey is tested by using the output of the global climate model. The projection results show a strong decrease in precipitation for almost all parts of the domain according to the output of the regional model. The intensity of drought conditions is projected to increase. According to the projection results, more arid conditions are expected in the region for the near future. Therefore, drier than present climate conditions are projected to occur more intensely over Turkey.

    Modeling of near future air temperature and precipitation climatology of Turkey and surrounding regions
    (TÜDAV, 2015) Turp, M. Tufan; Öztürk, Tuğba; Türkeş, Murat; Kurnaz, M. Levent
    Projected future changes in mean air temperature and precipitation for 2020 – 2050 were assessed with respect to the control period 1970 – 2000 via regional climate model simulations, using a regional climate model driven by three different global climate models, dynamically downscaled to 50 km for Turkey and surrounding regions, using the IPCC emission scenario outputs of global climate models.
