Abstract
Even in arid zones, the temporal variability of rare and minimum, but sometimes very violent, rainfall,has important consequences on the mainly pastoral economic life.
The authors study the characteristics of dry and rainy sequences along the Alger-Kano axis showing up the specific Hoggar effect.
By taking into account the various definitions of drought, they examine their significance for the climate of the Sahara desert.
