Don't have much time to put more to this, but as a first bit of info, QBO has had rapid and large swing into Easterly Phase, reminiscent of 09/10.

The Combined QBO and ENSO Influence on Tropical Cyclone Activity over the North Atlantic Ocean Abstract The Quasi-Biennal Oscillation (QBO) and the El Niño-Southern Oscillation (ENSO) largely modulate the zonal wind in the tropics. Previous studies showed that QBO phases produce changes in deep convection through an increase/decrease in the tropopause height over the tropics and subtropics. This study investigates the combined effects of QBO and ENSO on tropical cyclone activity by modulating tropopause height. We found that tropopause height increases over the Gulf of Mexico, the Caribbean region, and the Western North Atlantic Ocean during La Niña + QBOW, allowing deeper tropical convection to develop over those regions. As a consequence, TC activity over those regions is not only increased in number but also enhanced in intensity. Conversely, during El Niño + QBOE, most deep tropical convection is inhibited over those same regions due to the decrease in tropopause height over the subtropics. We conclude that QBO effects on TCs and deep convection should be studied in combination with ENSO. Additional comparative studies using long record data at high vertical resolution are needed to fully understand to what extent QBO interacts with ENSO in the lower tropical stratosphere and upper tropical troposphere. www.mdpi.com/2073-4433/12/12/1588/htm |

The obligatory request for more funding. No paper should be without it .....  |

So, if the QBO interacts with the MJO, that would result in a MOBJOQ (commonly abbreviated to MOJO). Sorry. Put this in your bookmarks/favourites for future reference: Acronyms & Abbreviations |

Best visual representation of QBO I've seen...
Decently Easterly right now, mostly the good stuff happens in this phase.
