Özet:

Temperature, which is one of the basic elements of climate, varies considerably from region to region on a temporal and spatial scale due to geographical features. As a result of global climate variations, the Central Anatolia region is one of the regions in Turkey that is frequently affected by these changes. For climate change research, it is important to determine the trends and changes in temperatures. In this study, the changes in temperature extremes were examined by using the daily maximum and minimum temperatures of 6 stations in the 1970-2020 period in Konya, which is located in the Central Anatolia region. 16 temperature indices proposed by WMO (World Meteorological Organization) and CLIVAR (Variability and Predictability of the Ocean-Atmosphere System), where we can observe the effect caused by global climate change, have been applied. R-based software called RClimdex and Mann Kendall test, which does not show parametric distribution, were used in the calculations. According to the results; In the study area, a decreasing trend was determined on frosty and icy days. Unlike the other stations, decreases were determined in the maximum of minimum temperatures index of Akşehir and Beyşehir stations located in the Lakes Region. The index of the length of the growing season, which has a positive effect on shortening the growth period of agricultural products, showed an increasing trend. When the temporal changes of the temperature indices were examined, decreases were observed in the extreme minimum temperature indices in general, while increases were observed in the extreme maximum temperature indices. The increases observed in extreme temperatures in Konya have negative effects both in terms of human and ecological aspects.
