Trend analysis of temperature and precipitation data of 9 stations located in Mediterranean region

Abstract

Trend is defined as a statistically significant decrease or increase in the measured values of a parameter over the time series. Since hydrological values are of randomly changing character over time, special methods should be used to investigate the tendency to decrease or increase. In this study, Linear Trend and Modified Mann-Kendall trend analyzes were examined using the annual average temperature data (̊C) and the annual total precipitation data (mm) between the years 1960-2020 of 9 stations in the Mediterranean Region. Study was performed in 95% confidence interval. According to the results of the study carried out there are increasing trends in temperature data in 8 of the 9 stations and no trend in precipitation data.
