Results show that the Interdecadal Pacific Oscillation (IPO) is the leading mode of SAMOC - SST covariability, explaining approximately 85 %, with the Atlantic Niño accounting for less than 10 % of the variability.
[Response: One thing that bothers me about the study is that no mention is made of what the covariability is between Nino3 SST and the Saharan dust index used.
