- Abstract
Climate change, is one of the biggest concerns on the planet today, due to its immediate and lasting repercussions on the natural environment and on humans. This study aims to characterize the climate variability in the Nouhao sub-basin in the central-eastern of Burkina Faso. To achieve this objective, monthly and annual climatological data of precipitation, temperature, sunshine and potential evapotranspiration are used over the period 1982-2014. Several statistical methods are used to evaluate the climate balance. The application of the centered indices reduced to the rainfall series highlighted climate variability characterized by an alternation of dry, normal and wet phase. Climate variability manifests itself in a progressive spatio-temporal dynamic of annual rainfall 0.45% over the decade 1995-2004 compared to 4.5% over the decade 2005-2014). It is also manifested by an increase in air temperature and a decrease in the duration of sunshine over the period 1982-2014. Despite the disruptions of the different seasons of the year, the monthly rainfall regimes were not changed.
