Drought is an insidious natural hazard that occurs in almost all climate types. Furthermore, the consequences
of drought are closely related to the vulnerability of the region/society in which it occurs. Drought vulnerability is based
on both biophysical and socioeconomic factors. In order to understand drought vulnerability, it may be a good idea to
first examine the physical and spatial characteristics of drought. In this regard, the intensity, and spatial characteristics
of the drought phenomenon in Turkey were investigated in this study using historical observation data. To begin, the
Standardized Precipitation and Evapotranspiration Index values were calculated using monthly temperature and
precipitation data from 221 weather stations spread across Turkey. Drought intensities are then calculated using the Run
Theory approach using these values. Finally, the Local Moran's Index, a spatial autocorrelation method, was used to
examine the spatial characteristics of drought intensity. According to the findings, 61 weather stations have significant
spatial clustering, while 160 have insignificant spatial clustering. Statistically, 24 of these 61 stations are highly
significant (p = 0.01). Furthermore, the high-high cluster (low drought density) is in northwest Turkey, according to the cluster map of Local-Moran autocorrelation coefficient. The low-low cluster (high drought density) is spatially dispersed
in Anatolia's western, southern, and central regions. In the remaining regions, no statistically significant cluster has been
identified
