Drought analysis in Mediterranean Region

Abstract

Drought is a natural disaster developing secretly. In this study, Standardized Precipitation Evapotranspiration Index (SPEI) has been applied for in Turkey's Mediterranean Region. Temperature and precipitation data were used for 8 meteorological observation stations. According to the data, 8 stations (Adana, Antalya, Burdur, Hatay/Antakya, Isparta, Kahramanmaras, Mersin and Osmaniye) were observed between 1970-2018. Frequency analyzes of SPEI values of 1, 3, 6, 9 and 12 months were calculated for each station. Monthly (1, 3, 6, 9 and 12 months) frequency values between the distribution of ear and wetlands is intended to make a comparison. Comparisons were made on how long the SPEI values were found in drought classes and on this availability. As a result, the data obtained from all stations in the Mediterranean region are between mild dry and near to normal. Mersin has the maximum value both in near to normal and dry conditions. When the minimum values are considered, Adana has the least percentage values in both wetness and dryness conditions compared to other stations.
