Abstract

Drought is considered as one of the  most important extreme climatic events which adversely affecting  the biosphere.

Monthly precipitation and  maximum and minimum temperatures data for three meteorological stations located in Syrian coastal region (lattakia-tartous-safita)were used during the period 1960-2016.Reconnaissance drought index (RDI) was applied to evaluate drought intensity at seasonal and annual time scales. Hargreves and Sammani equation  was used to calculate potential evapotranspiration.Trends with Mann-Kendall test  were used to detect changes in drought intensity. Whereas logistic distribution and differences in drought frequency  were computed  for two period  1960-1988 and 1988-2016, to estimate changes in drought frequency.

Results showed significant increase in annual drought  intensity owing to decreasing tendency in drought index values during spring and winter (ranging from 0.83 to 0.93 in spring) during the study period.

Also results showed increasing in extreme and moderate drought frequency at the last decades. These changes in drought characteristics well pose a big challenges for water resources management and agricultural production in this region.
