CHARACTERIZATION OF PRECIPITATION EXTREMES AND TRENDS IN TWO REGIONS OF NORTH AFRICA
ZEINEDDINE N., MURĂRESCU O.
ABSTRACT. – Characterization of precipitation extremes and trends in two regions of North Africa. To identify extreme precipitation, we use the “Standardized Precipitation Index” (SPI) method designed to determine periods of climatic drought. This research attempts to assess the synchronization of cycles of precipitation and trends in two regions of the Mediterranean basin, the Soummam Valley (north -
east of Algeria) and the Cap Bon which forming a peninsula in north-east Tunisia. The results show a severe climate drought observed in these regions from the late eighties and a rainfall return observed at end of the series ( but more confirmed in the Cap Bon region).
