As a consequence of climate change, frequency and intensity changes in extreme weather events have occurred. One of the most vulnerable regions of the world that is affected by the climate change is the Mediterranean region. Turkey as a Mediterranean country has a great importance to investigate the changes in climate behavior. 57 stations from Mediterranean climate region of Turkey have been selected as the study area for this thesis. This study aims to assess the climate indices that carry the valuable information about the climate of a region and detect trends and anomalies in those climate indices, precipitation and temperature patterns. 8 different General Circulation Model/Regional Climate Model couplings obtained from CORDEX project have been used in this study to make predictions on the period of 2011-2050. To evaluate the model performance and determine the most appropriate model, observed data and model data have been compared for the reference period 1971-2005. Five groups of climate indices which are percentilebased indices, absolute indices, threshold indices, duration indices and other indices have been calculated. The trends in climate indices, precipitation and temperature have been determined by applying the Mann-Kendall trend test. According to the results of the analyses, there are significant warming trend in temperature and temperature-related indices through the whole region and mixed pattern in precipitation and related indices

Assessing the impact of climate change on Mogan and Eymir Lakes' levels in Central Turkey Yagbasan, Ozlem; Yazıcıgil, Hasan (2012-05-01) Global warming is likely to have significant effect on the hydrological cycle. Some parts of the world may see significant reductions in precipitation or major alterations in the timing of wet and dry seasons. Climate change is one of the serious pressures facing water resources and their management over the next few years and decades. As part of the southern belt of Mediterranean Europe, Turkey is highly vulnerable to anticipated climate change impacts. The changes in global climate will seriously affect i...
Analysis of teleconnection patterns on climate of Northern Cyprus Nabango, Hope Nabwire; Akıntuğ, Bertuğ; Sustainable Environment and Energy Systems (2019-9) The complex interaction of components in the climate system has greatly contributed to uncertainty in climate patterns. Inarguably, anthropogenic factors have relentlessly increased this phenomenon. While innumerable research aimed at forecasting these interactions and their impacts on climate identify three streams of uncertainties as; model responses, external forcing factors and internal atmospheric variability, lack of knowledge on these factors have continue to challenge efficient results pertaining to...
Trend analysis of watershed-scale annual and seasonal precipitation in Northern California based on dynamically downscaled future climate projections Ishida, K.; Ercan, Ali; Trinh, T.; Jang, S.; Kavvas, M. L.; Ohara, N.; Chen, Z. Q.; Kure, S.; Dib, A. (2020-03-01) Impact of future climate change on watershed-scale precipitation was investigated over Northern California based on future climate projections by means of the dynamical downscaling approach. Thirteen different future climate projection realizations from two general circulation models (GCMs: ECHAM5 and CCSM3) based on four emission scenarios (SRES A1B, A1FI, A2, and B1) were dynamically downscaled to 9-km resolution grids over eight watersheds in Northern California for a period of 90 water years (2010-2100)...
Ecological impacts of global warming and water abstraction on lakes and reservoirs due to changes in water level and related changes in salinity Jeppesen, Erik; Brucet, Sandra; Naselli-Flores, Luigi; Papastergiadou, Eva; Stefanidis, Kostas; Noges, Tiina; Noges, Peeter; Attayde, Jose Luiz; Zohary, Tamar; Coppens, Jan; Bucak, Tuba; Menezes, Rosemberg Fernandes; Sousa Freitas, Francisco Rafael; Kernan, Martin; Sondergaard, Martin; Beklioğlu, Meryem (2015-05-01) According to the Intergovernmental Panel on Climate Change report released in September 2014, unprecedented changes in temperature and precipitation patterns have been recorded globally in recent decades and further change is predicted to occur in the near future, mainly as the result of human activity. In particular, projections show that the Mediterranean climate zone will be markedly affected with significant implications for lake water levels and salinity. This may be exacerbated by increased demands fo...
Intercomparison of the expected change in the temperature and the precipitation retrieved from CMIP6 and CMIP5 climate projections: A Mediterranean hot spot case, Turkey Bağçacı, Soner Çağatay; Yücel, İsmail; Düzenli, Eren; Yılmaz, Mustafa Tuğrul (2021-07-01) The performances of a large number of Global Circulation Models (GCMs) belonging to the latest release the Coupled Model Intercomparison Project phase 6 (CMIP6) in comparison with its predecessor CMIP5 are evaluated for monthly precipitation and temperature over Turkey (i.e. climate change hotspot). The ensemble of best top four models from both CMIP simulations is also used to investigate the future climate change under medium and high emissions for short, medium, and long terms. Results show CMIP6 product...
