Analysis Of Climatic Drought Using Drought Indices In Algiers Region
Authors : Ladji H. . Benrachdi, K. . Djoumad S. .
Abstract
Our research consists on the one hand to study the evolution of the rainfall data and the annual and monthly temperatures observed in the Algiers region and on the other hand to analyze the sequences of the climatic drought in using statistical methods such as drought indices. The statistical study of rainfall series in the Algiers region reveals a large variation of the wet and the dry years in space and time. The series of measurements of 1967-2015 are repeated in years of drought (moderate or high). Indeed, the last three decades (1980, 1990 and 2000) are particularly concerned by this situation of annual rainfall deficit.
