The intraseasonal timescale is attractive in Central Africa (CA) where socio-economic activities are highly based on rainfall. The parameterization of intraseasonal oscillations (ISO) then remains a great challenge for the improvement of sub-seasonal

The role of the intraseasonal oscillations (ISOs) in the tropical climate system has been widely investigated by researchers around the world. However for the better representation of ISOs in climate models, one of the greatest challenges remains the
