TL;DR: In this article, the impact of stratospheric ozone on the tropospheric general circulation of the Southern Hemisphere (SH) is examined with a set of chemistry-climate models participating in the Stratospheric Processes and their Role in Climate (SPARC)/Chemistry-Climate Model Validation project phase 2 (CCMVal-2).

TL;DR: In this article, three types of reference simulations, as recommended by the Chemistry-Climate Model Initiative (CCMI), have been performed with version 2.51 of the European Centre for Medium-Range Weather Forecasts Hamburg (ECHAM)/Modular Earth Submodel System (MESSy) Atmospheric Chemistry (EMAC) model.

TL;DR: The performance of 18 coupled chemistry climate models (CCMs) in the Tropopause Layer (TTL) is evaluated using qualitative and quantitative diagnostics as mentioned in this paper, using both quantitative and qualitative metrics.

TL;DR: Sudden stratospheric warmings (SSWs) are impressive fluid dynamical events in which large and rapid temperature increases in the winter polar stratosphere (10−50km) are associated with a complete reversal of the climatological wintertime westerly winds.

TL;DR: In this paper, a suite of chemistry-climate models (CCMs) have been analyzed to assess the two distinct milestones of ozone returning to historical values (ozone return dates) and ozone no longer being influenced by ODSs (full ozone recovery).
