As stated, the non-stationary nature of the interannual SST-forced teleconnections with the Sahel rainfall has been merely found out in observational studies (e.g., Janicot et al. 1996; Fontaine et al. 1998; Mohino et al. 2011; Rodríguez-Fonseca et al. 2011, 2015; Losada et al. 2012; Diatta and Fink 2014). In this way, the teleconnections are found to be strengthened or weakened depending on the sequence of decades under study. However, this evidence remains observational, and no physical explanation has been addressed so far, including the impact on predictability.
