Along with strengthening upwelling, tropospheric expansion contributes at leading order to reductions in tropical lower stratospheric ozone.

We hypothesize that QBO amplitude responds to global warming by shifting upwards along with the expanding tropopshere.

Key aspects of the 2015/2016 QBO disruption can be explained with the classical theory of the QBO. This theory predicts key aspects of the 2019/2020 as well.

We show that the previous theory for the formation of the buffer zone of the QBO is circular. We proposed an updated theory: mean flow damping forms the buffer zone of the QBO.

The region where there is low QBO power despite sufficient vertically propagating wave activity to drive a QBO—the buffer zone—appears to be formed by mean flow damping due to horizontal eddy momentum flux divergence.

How has the sudden stratospheric warming (SSW) definition changed, and how sensitive is the detection of SSWs to the definition used?
