In this context, various studies are carried out in our country and in the world in order to reduce the effects of climate change. In the study, homogeneities and trends of precipitation, temperature and wind speed series of 31 stations in the Black Sea region were investigated. In addition, evaluations were made considering possible tendencies to disrupt homogeneity. In homogeneity analysis, Standard Normal Homogeneity Test (SNHT), Buishand Range Test (BRT), Pettitt Test (PT) and Von Neumann Ratio Test (VN), known as Absolute homogeneity tests, were used. Possible trends of stations were investigated using Spearman's Rho (SR) and Mann Kendall (MK) tests. According to the results of the homogeneity analysis, while the precipitation series of 30 stations were homogeneous, three stations were determined as homogeneous in the wind speed results. When the temperature series of the stations were examined, it was determined that the homogeneity was impaired in all stations. According to the results of the trend analysis, the significant increase trends determined especially in the temperature series show that the region started to warm up over time as an effect of global climate change.Son yillarda küresel iklim degisikligi etkilerinden kaynaklanan afet sayilarinda hissedilebilir bir artis görülmektedir. Bu kapsamda iklim degisikligi etkilerini azaltmak amaciyla ülkemizde ve dünyada çesitli çalismalar yapilmaktadir. Çalismada, Karadeniz bölgesindeki 31 istasyona ait yagis, sicaklik ve rüzgar hizi serilerinin homojenlikleri ve egilimleri arastirilmistir. Ayrica olasi egilimlerin homojenligi bozdugu düsünülerek degerlendirmelerde bulunulmustur Homojenlik analizinde Mutlak homojenlik testleri olarak bilinen Standart Normal Homojenlik Testi (SNHT), Buishand Aralik Testi (BRT), Pettitt Testi (PT) ve Von Neumann Oran Testi (VN) kullanilmistir. Istasyonlarin olasi egilimleri ise Spearman’in Rho (SR) ve Mann Kendall (MK) testleri kullanilarak arastirilmistir. Homojenlik analizi sonuçlarina göre 30 istasyonun yagis serileri homojenken, rüzgar hizi sonuçlarinda üç istasyon homojen olarak belirlenmistir. Istasyonlara ait sicaklik serileri incelendiginde tüm istasyonlarda homojenligin bozuldugu belirlenmistir. Egilim analizi sonuçlarina göre özellikle sicaklik serilerinde belirlenen anlamli artis egilimleri küresel iklim degisikliginin bir etkisi olarak bölgenin zamanla isinmaya basladigini göstermektedir.trinfo:eu-repo/semantics/openAccessTrend AnalysisHomogeneity AnalysisBlack Sea RegionPrecipitationTemperatureWind Speed.Article6112914510.51764/smutgd.1260628https://doi.org/10.51764/smutgd.1260628
