Roughly 90% of atmospheric ozone is found in the lower stratosphere in the ozone layer. Since about the 1970s, anthropogenic emissions of ozone-depleting gases have led to depletion of ~3–4% of the total overhead ozone averaged over the globe 1 . The strongest depletion is found over Antarctica during spring, when photochemical processes combine with a unique set of meteorological conditions to greatly increase the effectiveness of ozone-depleting gases, and more than half of the total overhead… 

The Antarctic ozone hole during 2018 and 2019

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

On the surface impact of Arctic stratospheric ozone extremes

A comprehensive stratosphere-resolving atmospheric model, with interactive stratospheric ozone chemistry, coupled to ocean, sea ice and land components is used to explore the tropospheric and surface

Ozone-climate links in the Southern Hemisphere.

This thesis details a number of the effects that changes in the abundance of stratospheric ozone over the period 1950-2100 are having on climate in the Southern Hemisphere. Beginning in the 1970s

Influences of the Antarctic Ozone Hole on Southern Hemispheric Summer Climate Change

AbstractOver the past three decades, Antarctic surface climate has undergone pronounced changes. Many of these changes have been linked to stratospheric ozone depletion. Here linkages between

Springtime arctic ozone depletion forces northern hemisphere climate anomalies

Large-scale chemical depletion of ozone due to anthropogenic emissions occurs over Antarctica as well as, to a lesser degree, the Arctic. Surface climate predictability in the Northern Hemisphere

The impact of polar stratospheric ozone loss on Southern Hemisphere stratospheric circulation and climate

Abstract. The impact of polar stratospheric ozone loss resulting from chlorine activation on polar stratospheric clouds is examined using a pair of model integrations run with the fully coupled

Dynamical mechanisms for the recent ozone depletion in the Arctic stratosphere linked to North Pacific sea surface temperatures

The stratospheric ozone layer, which prevents solar ultraviolet radiation from reaching the surface and thereby protects life on earth, is expected to recover from past depletion during this century

Twenty-first century Southern Hemisphere impacts of ozone recovery and climate change from the stratosphere to the ocean

Abstract. Changes in stratospheric ozone concentrations and increasing concentrations of greenhouse gases (GHGs) alter the temperature structure of the atmosphere and drive changes in the atmospheric

Impacts of Stratospheric Ozone Extremes on Arctic High Cloud

<p>Stratospheric ozone depletion in the Antarctic is well known to cause changes in Southern Hemisphere tropospheric climate; however, because of its smaller magnitude in the Arctic, the effects of

Stratospheric Ozone Depletion: An Unlikely Driver of the Regional Trends in Antarctic Sea Ice in Austral Fall in the Late Twentieth Century

It has been suggested that recent regional trends in Antarctic sea ice might have been caused by the formation of the ozone hole in the late twentieth century. Here we explore this by examining two

Since the 1970s sea ice extent has decreased dramatically in the Northern Hemisphere and increased slightly in the Southern Hemisphere, a difference that is potentially explained by ozone depletion

Cooling of the Arctic and Antarctic Polar Stratospheres due to Ozone Depletion

Abstract Long time records of stratospheric temperatures indicate that substantial cooling has occurred during spring over polar regions of both hemispheres. These cooling patterns are coincident

Southern Hemisphere climate response to ozone changes and greenhouse gas increases

While most of the Earth warmed rapidly during recent decades, surface temperatures decreased significantly over most of Antarctica. This cooling is consistent with circulation changes associated with

Impact of Polar Ozone Depletion on Subtropical Precipitation

TLDR
It is shown that precipitation in the southern subtropics in austral summer increases significantly when climate models are integrated with reduced polar ozone concentrations, and highlights the importance of polar regions for the subtropical hydrological cycle.

The Impact of Stratospheric Ozone Recovery on the Southern Hemisphere Westerly Jet

TLDR
Owing to the expected disappearance of the ozone hole in the first half of the 21st century, the CCMVal models predict that the tropospheric westerlies in Southern Hemisphere summer will be decelerated, on the poleward side, in contrast with the prediction of most IPCC/AR4 models.
