Water In, Ozone Out The danger of stratospheric ozone loss burst into public awareness in the 1980s, when the Antarctic ozone hole was discovered and described. Since then, the specter of ozone depletion in other locations, notably the Arctic, has been identified. Ozone loss is not confined to high latitudes, however, nor is it only the result of the addition of anthropogenic compounds containing chlorine and bromine in the stratosphere, as Anderson et al. (p. 835, published online 26 July; see… 
Stratospheric ozone over the United States in summer linked to observations of convection and temperature via chlorine and bromine catalysis
TLDR
Observations of the frequency and depth of penetration of convectively injected water vapor into the stratosphere, triggered by severe storms that are specific to the central United States in summer, and model their effect on lower stratospheric ozone are reported.
Mechanism of ozone loss under enhanced water vapour conditions in the mid-latitude lower stratosphere in summer
Abstract. Water vapour convectively injected into the mid-latitude lowermost stratosphere could affect stratospheric ozone. The associated potential ozone loss process requires low temperatures
Potential of future stratospheric ozone loss in the midlatitudes under global warming and sulfate geoengineering
Abstract. The potential of heterogeneous chlorine activation in the midlatitude lowermost stratosphere during summer is a matter of debate. The occurrence of heterogeneous chlorine activation through

Abstract. The potential of heterogeneous chlorine activation in the mid-latitude lowermost stratosphere during summer is a matter of debate. The occurrence of heterogeneous chlorine activation
Chlorine in the stratosphere
Water Vapor in the Lower Stratosphere
TLDR
It is argued that there is evidence for water vapor enhancements in the mid-latitude lower stratosphere and that increased water vapor levels could enhance ozone depletion caused by human-emitted ozone-depleting substances and thus raise ultraviolet radiation levels at Earth's surface.
Volcanic Perturbations of Stratospheric Ozone in Contemporary and Future Atmospheres
Volcanic eruption columns possess the potential to transport great quantities of reactive gases to the stratosphere where they might subsequently interact with ozone. While explosive volcanic

TLDR
The effect of HNO3 removal is dependent on the magnitude of nitric acid removal and has the greatest potential to increase chlorine activation and ozone loss under UTLS conditions that weakly favor the chlorine activation heterogeneous reactions by reducing NOx sources.
Convectively injected water vapor in the North American summer lowermost stratosphere
Anderson et al. (2012) (A2012) report in situ observations of convectively injected water vapor (H2O) in the North American (NA) summer lowermost stratosphere (LMS), occasionally exceeding 12ppmv.

Free Radicals Within the Antarctic Vortex: The Role of CFCs in Antarctic Ozone Loss
TLDR
Recent advances in understanding of the kinetics, photochemistry, and structural details of key intermediates in these catalytic cycles as well as an improved absolute calibration for ClO and BrO concentrations at the temperatures and pressures encountered in the lower antarctic stratosphere have been essential for defining the link.
The effect of climate change on ozone depletion through changes in stratospheric water vapour
Several studies have predicted substantial increases in Arctic ozone depletion due to the stratospheric cooling induced by increasing atmospheric CO2 concentrations. But climate change may

TLDR
It is demonstrated that chemical ozone destruction over the Arctic in early 2011 was—for the first time in the observational record—comparable to that in the Antarctic ozone hole.
