- W2213202130 abstract "L’Algerie a connu, au cours de ces vingt dernieres annees, une secheresse intense et persistante. Cette secheresse, caracterisee par un important deficit pluviometrique, a touche l’ensemble de l’Algerie et plus particulierement sa partie nord-occidentale. Des secheresses analogues, aussi bien en amplitude qu’en intensite, ont deja ete observees au debut du 20eme siecle, entre 1910 et 1940. Dans cette etude nous nous sommes interesses a une analyse historique de la secheresse climatique a l’echelle annuelle, afin de suivre son evolution par decennies, de 1920 a 1990. Nous essayerons de caracteriser cette secheresse, de la quantifier et enfin d’etudier sa variation spatio-temporelle. Ce travail a ete realise a l’aide de deux approches : L’etude du deplacement du sud vers le nord de l’isohyete 400 mm, qui met en evidence l’ampleur de l’extension geographique du phenomene. L’analyse cartographique automatique de l’indice pluviometrique centre-reduit de sept decennies (de 1920 a 1990), mettant en evidence l’importance de l’evolution vers le nord de cet indice Algerian has witnessed during the last twenty years an intense and persistent drought. This drought which is characterized by an important rainfall deficit has affected the whole of Algeria particularly the north - west part.Similar droughts in amplitude and intensity have yet been noticed at the beginning of the century, between 1910 and 1940. In our study we devoted ourselves to historical analysis of drought on the annual scale. This has allowed us to follow its evolution decade by decade from 1920 to 1990. We tried in the first step to characterize this drought. Then to quantify it and at last to study its variability in space through two approach methods: calculation of the advance of the South to the North, the isohyet 400mm, which stresses the importance of the geographical extension of the phenomenon, and the automatic cartography of the rainfall indications per decade from 1920 to 1990" @default.
