Trend analysis of precipitation and temperature in the Western Black Sea region of Türkiye

Abstract

Climate change indicates alterations in climate parameters, involving both increases and decreases. Trend analysis enables the identification and direction of these changes. This study aims to conduct trend analysis in the Western Black Sea region of Türkiye. Non-parametric tests like Mann-Kendall and Theil-Sen Slope were employed to define temperature and precipitation changes in the region. In the analysis annual mean temperature (°C) and total annual precipitation (mm) data were used, collected from 15 different stations across the region. Mapping has been applied to visualize the results for better understanding of the findings. The results indicate an insignificant trend in precipitation across most of the region, while the temperature clearly demonstrates an upward trend.
