      abstract     = {The stratospheric circulation determines the transport and
                      lifetime of key trace gases in a changing climate, including
                      water vapor and ozone, which radiatively impact surface
                      climate. The unusually warm El Niño–Southern Oscillation
                      (ENSO) event aligned with a disrupted Quasi-Biennial
                      Oscillation (QBO) caused an unprecedented perturbation to
                      this circulation in 2015–2016. Here, we quantify the
                      impact of the alignment of these two phenomena in
                      2015–2016 on lower stratospheric water vapor and ozone
                      from satellite observations. We show that the warm ENSO
                      event substantially increased water vapor and decreased
                      ozone in the tropical lower stratosphere. The QBO disruption
                      significantly decreased global lower stratospheric water
                      vapor and tropical ozone from early spring to late autumn.
                      Thus, this QBO disruption reversed the lower stratosphere
                      moistening triggered by the alignment of the warm ENSO event
                      with westerly QBO in early boreal winter. Our results
                      suggest that the interplay of ENSO events and QBO phases
                      will be crucial for the distributions of radiatively active
                      trace gases in a changing future climate, when increasing El
                      Niño-like conditions and a decreasing lower stratospheric
                      QBO amplitude are expected.},
