Abstract
Climate change shows itself in various scales in the Mediterranean and Sahara region. The study aims at characterizing climate of the Sahara in a bigger scale otherwise-said, precision as for the current climate reigning (evolution), at the level of the region of Ouargla. For that purpose, we adopted a complementary, dynamic and static approach. The dynamic approach was approached by compilations of the previous works. Followed by a static analysis, leaning on climatological data, spread over a period going from 1978 till 2015. It emerges from it that the dynamic character is characterized by the frequency of the regime NAO + with regard to that of the NAO-. This regime expresses himself daily, in terms, of temperature and haste, explaining the importing lived reheating these last decades. So, the results show that the region is characterized by a "hot" thermoclimate, expressed by all the energy parameters (rise of the fraction of sunstroke and the temperature) and a "dry"ombroclimate.
