ABSTRACT: This study investigates
climatic parameters (rainfall, and temperature) over Burkina Faso and the
possible role of solar activity and its induced energies. Through morphological
investigations, we
analyzed solar activity indices (sunspot number, IMF, PC index, Cosmic rays)
over the last three solar cycles (1975-2020). Results about interplanetary
heating show that joule heating is well correlated with the dynamic pressure of the
solar plasma. Climate parameters (rainfall, Temperature) variabilities are
modulated by disturbances in solar activity: 1) quiet solar characterized by a drop in solar plasma’s
parameters is associated with important cloud cover and consequently bring
important rainfall which chills terrestrial atmosphere, 2) active solar
characterized by important input energy is associated with weak incident cosmic
ray consequently with low cloudiness which brings warming. Thus, the possible natural link can be
suggested between solar activity and climatic parameters even if it is not the
only factor of global warming.
