Examining the changes in the characteristics of different hydrometeorological phenomena over time within the framework of climate change: Anamur case study

Öz

In this study, using monthly data measured between 2002 and 2019 at the Anamur station number 17320, operated by the General Directorate of Meteorology, the change in the character of the dominant phenomena in the study area was examined within the framework of climate change over time. For this purpose, Factor Analysis (FA) was dynamically applied to the data to monitor temporal changes and the findings were interpreted within the framework of climate change. As a result of the study, it was concluded that there are two dominant phenomena in the study area, namely temperature, and wind and that these two phenomena increase their effects over time. On the other hand, in line with the findings obtained from the study, it was observed that the Temperature, Open Surface Evaporation, Wind Speed and Relative Humidity parameters increased their effects by %2.61, %3.32, %3.38 and %13.60, respectively, between 2011 and 2019. Again, the findings show that there is an impact of climate change. The dynamic application of FA has created a very productive approach to examining the change in the characters of the phenomena, and this approach represents the innovative and original aspect of the current study.

Farklı hidrometeorolojik fenomenlerin karakterlerindeki değişimin zamana bağlı olarak iklim değişikliği çerçevesinde incelenmesi: Anamur örneği

Öz

Bu çalışmada Meteoroloji Genel Müdürlüğü tarafından işletilen 17320 numaralı Anamur istasyonunda 2002-2019 yılları arasında ölçülen aylık veriler kullanılarak bölgedeki hâkim olguların karakterindeki değişim zamana bağlı olarak iklim değişikliği çerçevesinde incelenmiştir. Bu amaçla verilere Faktör Analizi (FA) dinamik bir biçimde uygulanarak zamansal değişim izlenmiş ve elde edilen bulgular iklim değişikliği çerçevesinde yorumlanmıştır. Yapılan çalışma sonucunda sıcaklık ve rüzgâr olmak üzere bölgede iki hâkim fenomenin var olduğu ve bu iki olgunun da zamanla etkisini arttırdığı sonucuna ulaşılmıştır. Diğer taraftan yapılan çalışmadan elde edilen bulgular doğrultusunda Sıcaklık, Açık Yüzey Buharlaşması, Rüzgâr Hızı ve Nisbi Nem parametrelerinin 2011-2019 yılları arasında etkilerini sırasıyla %2.61, %3.32, %3.38 ve %13.60 oranlarında arttırdıkları görülmüştür. Yine elde edilen bulgular bölgede iklim değişikliğinin etkisinin var olduğunu göstermektedir. FA’nın dinamik bir biçimde uygulanması olguların karakterlerindeki değişimin incelenmesinde oldukça verimli bir yaklaşım tarzı oluşturmuş olup bu yaklaşım tarzı mevcut çalışmanın yenilikçi ve orijinal yönünü temsil etmektedir.
