Quasi-stationary planetary waves in late winter Antarctic stratosphere temperature as a possible indicator of spring total ozone [PDF]
Stratospheric preconditions for the annual Antarctic ozone hole are analyzed using the amplitude of quasi-stationary planetary waves in temperature as a predictor of total ozone column behaviour.

The impact of the mixing properties within the Antarctic stratospheric vortex on ozone loss in spring [PDF]
Calculations of equivalent length from an artificial advected tracer provide new insight into the isentropic transport processes occurring within the Antarctic stratospheric vortex. These calculations show two distinct regions of approximately equal area:

Early indications of anomalous behaviour in the 2019 spring ozone hole over Antarctica [PDF]
The level of quasi-stationary planetary wave (QSW) activity in the Antarctic winter stratosphere provides insights into the likely behaviour of the ozone hole in the following spring months. Observation of anomalously large amplitude of the QSW in winter

Potential drivers of the recent large Antarctic ozone holes
The past three years (2020–2022) have witnessed the re-emergence of large, long-lived ozone holes over Antarctica. Understanding ozone variability remains of high importance due to the major role Antarctic stratospheric ozone plays in climate variability

The Lagrangian structure of ozone mini-holes and potential vorticity anomalies in the Northern Hemisphere [PDF]
An ozone mini-hole is a synoptic-scale area of strongly reduced column total ozone, which undergoes a growth-decay cycle in association with baroclinic weather systems. The tracks of mini-hole events recorded during the TOMS observation period over

Changes in the polar vortex: Effects on Antarctic total ozone observations at various stations [PDF]
October mean total column ozone data from four Antarctic stations form the basis for understanding the evolution of the ozone hole since 1960. While these stations show similar emergence of the ozone hole from 1960 to 1980, the records are divergent in ...

Effects of prescribed CMIP6 ozone on simulating the Southern Hemisphere atmospheric circulation response to ozone depletion [PDF]
The Antarctic ozone hole has led to substantial changes in the Southern Hemisphere atmospheric circulation, such as the strengthening and poleward shift of the midlatitude westerly jet.

The Antarctic ozone hole during 2018 and 2019 [PDF]
While the Montreal Protocol is reducing stratospheric ozone loss, recent increases in some ozone depleting substance (ODS) emissions have been identified that may impact southern hemisphere climate systems.
