Kahramanmaraş İlinde Yağışların Trend Analizi (Precipitation Trend Analyses in Kahramanmaraş)

Turkish Abstract: Turkiye, dunyada kisa veya uzun sureli iklim degisikliklerinin yasanabilecegi hassas ulkelerden birisini olusturmaktadir. Bu calismada, 1975–2005 yillari arasinda Akdeniz Bolgesi’nde yer alan Kahramanmaras’ta bulunan meteoroloji istasyonlari icin yillik, mevsimlik ve aylik yagis trendleri incelenmistir. Parametrik olmayan testler (Mann-Kendall), lineer regresyon, yagis degiskenligi, degisim katsayisi gibi istatistiksel metotlar kullanilarak yagis egilimleri analiz edilmistir. Sonuclar, calisma alaninda yillik yagislarda cok kucuk azalisa ragmen istatistiksel anlamlilikta pozitif veya negatif bir trendin olusmadigini gostermektedir. Kis, ilkbahar ve yaz mevsimlerinde calisma periyodu boyunca yagislarda cok onemsiz bir azalis gerceklesirken, sonbahar mevsiminde ise istatistiksel anlamda onemsiz bir artis trendi gozlenmistir. English Abstract: Turkey is one of the sensitive areas to climate variation in the World. In this study, trends in precipitation at annual, seasonal and monthly time scales for the periods of 1975-2005 were examined for the Kahramanmaras which is mostly located in the Mediterranean region of Turkey. Non-parametric tests (such as Mann-Kendall), linear regression, coefficient of variation techniques were used to determine rainfall trends. The results showed that there is no negative or positive statistically significant trend in the study area, despite of slight precipitation decrease annually for the period of 1975-2005. Slight precipitation decreases (which are not statistically significant) for winter, spring and summer were determined. In contrast, slight precipitation increase was found for the season autumn.
