Özet:

Today, anthropogenic changes that occur through human interventions in the environment are one of the most important problems on a global scale. The subject of the study is to evaluate the characteristics of the alansal and timelines of extreme weather events in the context of climate change/changing. In this context, the temperature data of the meteorological stations in the Marmara Region have been analyzed in the context of extreme temperatures. The Marmara region is a significant climate transition area due to its geographical location and is also geomorphologically in its differences. The data used in the framework of the study was provided by the General Directorate of Meteorology. The homogenity of temperature data has been tested by Pettitt, Buishand Order and Standard Normal Homogenity Tests. The indicators are then calculated by the ETCCDMI (Climate Change Detection, Imaging and Index Expert Group). In the framework of homogenity analyses, the temperature data has detected fractures in certain years. The breakdowns were observed in the years 1997-98 and 2006-2007. The reasons for this can include unnatural interference with the stations used, changes in the measurements of data sets, the effects of elements such as urbanization. Also, climate change, which we often begin to see its effects at extreme temperatures, causes the homogeneity in data to be deteriorated. The results of extreme temperature indicators have seen alansal and temporary (seasonal) changes. There is a distinct difference in the area of work, especially in the city/city. The number of hot days and nights in stations such as Istanbul, Bursa and Fiskesir, where urbanization is clearly observed, is high, while the number of hot days and nights is low in rural areas. There are also changes within the limits. In the cold days and cold nights, the summer and winter seasons are very rare. Instead, a significant increase in hot day and hot night indices is dominant.
