INVESTIGATION OF PRECIPITATION DATA OF DİYARBAKIR PROVINCE WITH DIFFERENT TREND ANALYSIS METHODS

Abstract

Global climate change leads to significant alterations in climate systems, affecting natural resource management, agriculture, and water security. As these impacts are also felt at the local level, regional climate analyses are crucial. This study analyzes precipitation data from Diyarbakır province between 1970 and 2022 to examine the local effects of climate change. Trend analyses were conducted using Mann-Kendall, Sen's Slope, Spearman’s Rho, and Innovative Trend Analysis (ITA) methods. The Mann-Kendall test assessed the statistical significance of trends, while Sen's Slope estimated the magnitude of these trends. The results indicated no statistically significant trends on an annual or seasonal basis. However, the ITA method revealed decreasing trends in summer precipitation and annual totals, alongside increasing trends in spring and autumn precipitation. No trends were detected for winter precipitation. The Spearman’s Rho test identified a positive relationship between annual total precipitation and seasons, but no trends were observed among the seasons themselves. This study highlights the importance of local climate analyses and contributes to preparedness for future changes. Continuous monitoring of climate data plays a critical role in making informed strategic decisions, particularly in water resource management and agricultural policies.

Öz

Küresel iklim değişikliği, iklim sistemlerinde büyük değişikliklere yol açarak, doğal kaynakların yönetimi, tarım ve su güvenliğini etkilemektedir. Bu etkiler yerel düzeyde de hissedildiği için, bölgesel iklim analizleri büyük önem taşımaktadır. Bu çalışmada, Diyarbakır ilinin 1970-2022 yılları arasındaki yağış verilerini analiz ederek iklim değişikliğinin yerel etkilerini incelenmiştir. Mann-Kendall, Sen's Slope, Spearman’s Rho ve Yenilikçi Trend Analizi (ITA) yöntemleri kullanılarak yağış verileri üzerinde trend analizleri yapılmıştır. Mann-Kendall testi trendlerin istatistiksel anlamlılığını, Sen's Slope ise trendlerin eğimini değerlendirmiştir. Sonuçlar, yıllık ve mevsimsel bazda anlamlı bir trend olmadığını göstermiştir. ITA yöntemi, yaz mevsiminde ve yıllık toplam yağışta azalma, ilkbahar ve sonbaharda artış trendleri ortaya koyarken, kış mevsiminde bir trend bulunmamıştır. Spearman’s Rho testi, yıllık toplam yağış ve mevsimler arasında pozitif bir ilişki belirlemiş, ancak mevsimler arasında trend görülmemiştir. Bu çalışma, yerel iklim analizlerinin önemine işaret etmekte ve gelecekteki değişikliklere hazırlıklı olma konusunda katkı sağlamaktadır. İklim verilerinin sürekli izlenmesi, stratejik kararlar için kritik bir rol oynamaktadır.
