Özet

In this study, Kahramanmaras Central District is aimed to determine the years which are arid or rainy by taking average of annuals in winter, spring, summer, autumn seasons between the years 1995 and 2014, and to calculate the possibility of temporary dry or rainy in future years. TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method was chosen to estimate as a creating a model requires 6 parameters (long-term, average minimum temperature and maximum temperature, average minimum and maximum relative humidity, average annual precipitation, total annual precipitation) in this direction. For this purpose, data of Kahramanmaras Meteorological Station, which has the longest rainfall records in the region, are used. In this study, days with less than 2.5 mm of rainfall were considered dry, and days with 2.5 mm or more of rainfall were considered rainy. TOPSIS method resulted in 6 steps and meteorological droughts were detected in 2002, 2008 and 2011. In 2015, 2016 and 2017, there is the possibility of a gradual drought.
