Tokat İlinde Mevsimsel Yağışların CLIGEN İklim Modeli ile Değerlendirilmesi

Hidrolojik, ekolojik ve tarımsal verimlilik arasındaki ilişkiyi tahmin eden modeller oldukça yaygın bir şekilde kullanılmaktadır. Günümüzde, CLIGEN en yaygın kullanılan iklim modelidir. Dünyanın pek çok ülkesinde oldukça yaygın bir şekilde kullanılırken; ülkemizde kullanımı yaygın değildir. Bu çalışmada, Tokat iklim şartlarına ait günlük veriler CLIGEN ile simüle edilmiştir. Gözlenen ve simüle edilen yağışlar ıslak/kuru olarak sınıflandırılmıştır. Mevsimler zaman aralığında ıslak/kuru durumuna göre CLIGEN iklim modelinin performansı değerlendirilmiştir. Bulunan yağış verileri arasındaki ilişki Kolmogorov-Smirnov ve t-testine göre istatistiksel olarak incelenmiştir. Tokat, kurak ve yarı kurak iklim kuşağında yer almaktadır. Tüm mevsim zaman aralığında, kurak yağışlara göre modelin performansı yüksek bulunmuştur.

Validation of The Weather Generator CLIGEN with Season Precipitation Data in Tokat Province

In models that predict hydrologic, ecological and product-yield relationship, the climate interfacefile is widely used. Today, CLIGEN is the most widely used climate model. While this model isextensively used in many countries around the world, it is not used commonly in our country. In thisstudy, daily data belonging to Tokat climate conditions were simulated with CLIGEN. Observedand simulated precipitation was classified as the wet/dry period. The performance of the CLIGENclimate model was evaluated in both wet and dry periods according to the seasons. The relationshipbetween the obtained precipitation data was statistically determined by Kolmogorov-Smirnov andt-test. Tokat province is located in the arid and semi-arid climate zone. The performance of the modelin predicting precipitation in all seasons during the dry period was found to be quite successful.
