Abstract

Climate change is expressed as major changes in the average climate which exist for many years. Although climate change occurs on a global scale, the impact of climate change varies from region to region. Therefore, the analysis of the variations in meteorological variables is a very vital issue in monitoring of climate change. In this study, assignment of the change points and trends of annual temperature (Tmean, Tmin and Tmax) data of the Konya Closed Basin in Turkey is examined. For this aim, air temperature data of 11 meteorology station were used. The change point of temperature data was examined using the Pettitt test, Standard Normal Homogeneity test and Buishand Range test. The Mann-Kendall, Spearman Rho and Innovative Şen Trend methods were used to determine trends of air temperature. Most of the change points in annual temperature data were determined as 1993-1994. The trend results show that annual temperature at most stations have increased, more than 80% of which are statistically significant.

Homogeneity and Change Point Detection Analysis of Seasonal and Annual Precipitation and Temperature Series Van, Türkiye

“…In past studies, homogeneity analysis was applied to the total precipitation, maximum, minimum, and average temperature series in different regions of Turkey. When we examine the studies conducted, we can observe that while the homogeneity of the temperature series has deteriorated (Ay, 2020;Yaman & Ertuğrul 2020), it is generally homogenous in the precipitation series , Hırca ve Eryılmaz Türkkan, 2020, Yaman & Ertuğrul 2020, Koycegız & Buyukyıldız 2020. These studies were found to be similar to the results of our results regarding the Van region.…”

Temperature series analysis of the Hirfanli Dam Basin with the Mann-Kendall and Sequential Mann-Kendall tests

“…The existence of an increasing trend in annual temperature records has been ascertained by various trend analysis methods in the Central Anatolia region and the Kizilirmak River basin [21,25,39,[43][44][45][46][47][48].…”

“…They stated that the temperatures in the region are in an increasing trend. Köyceğiz and Buyukyildiz [21] researched the trends of annual average temperature, maximum temperature and minimum temperature data of Konya Closed Basin, stating that more than 80% of the annual temperature series has a statistically significant increasing trend.…”
