Mapping spatio-temporal tendencies of climate types in Geographic Information Systems (GIS) media: A case study in Şanlıurfa and its environs (original) (raw)

Aims: The primary objective of this study was to figure out spatio-temporal tendencies of climate-types in Şanliurfa town and its environs, located in the Southeastern Anatolia Project (GAP) area, through using Erinc Drought Index method. Methods and Results : Data sets consisting of long-term (1965-2018) annual total precipitation as well as average annual maximum temperature series of Şanliurfa, Birecik, Akcakale, Ceylanpinari, Siverek and Bozova meteorological stations -distributed unevenly over total surface area of 19 242 km²- were obtained and utilized in order to calculate Erinc Drought Index (EDI) on a yearly basis. EDI time series of each station was divided into three non-overlapping and successive parts or periods, i.e. period-1 (1965-1981), period-2 (1982-1999), period-3 (2000-2018). The best fitting probability distribution models to the EDI series of each period were, in turn, determined by performing a regular frequency analysis procedure by Kolmogorov-Smirnov Goodnes...
