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
mean temperature, maximum temperature and minimum temperature 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 time series 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.

KONYA KAPALI HAVZASI (TÜRKİYE) YILLIK SICAKLIK VERİLERİNİN TREND ANALİZİ VE DEĞİŞİM NOKTALARININ BELİRLENMESİ

Abstract

İklim
değişikliği, uzun yıllar için var olan iklim ortalamalarındaki büyük değişimler
olarak ifade edilmektedir. İklim değişikliği küresel ölçekte gerçekleşse de, etkileri
bölgeden bölgeye değişmektedir. Bu nedenle, meteorolojik değişkenlerdeki
değişikliklerin analizi iklim değişikliğinin izlenmesinde çok önemli bir
konudur. Bu çalışmada, Türkiye’deki Konya Kapalı Havzası’nın yıllık ortalama
sıcaklık, maksimum sıcaklık ve minimum sıcaklık verilerinin trendlerinin ve değişim
noktalarının belirlenmesi incelenmiştir. Bu amaçla 11 meteoroloji istasyonunun hava
sıcaklığı verileri kullanılmıştır. Sıcaklık zaman serisi verilerinin değişim
noktası Pettitt testi, Standart Normal Homojenlik testi ve Buishand Range testi
kullanılarak incelenmiştir. Hava sıcaklığı trendlerini belirlemek için
Mann-Kendall, Spearman Rho ve Yenilikçi Şen Trend yöntemleri kullanıldı.
