Experimenting on the QBO acceleration time-series with very short training intervals, the part shaded in yellow. Interesting how much information content is stored in a short 3 to 4 year interval. The training part is duplicated almost exactly in several parts of the time series (see ~1998, e.g.) using the exact Draconic lunar period, aliased to the annual cycle.
And stating the obvious, but a massive hurricane about to hit Florida very soon.
The consensus is that Atlantic hurricanes start off the equatorial coast of Africa. There are apparently correlations of hurricane occurrences and strength with the direction of QBO so just another reason to understand QBO.
