One thing I have noticed about SSW is that they tend to stagnate the MJO in whatever phases it was in at the onset....this is what ruined 2018-2019, and made that season look like a la nina during what should have been a prime time of a prolific, weak, modoki el nino season. That has also happened this season with the first SSW, however, I think the MJO is finally staggering into more favorable phases should this SSW succeed.
