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 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).
Journal ArticleDOI
A negative phase shift of the winter AO/NAO due to the recent Arctic sea‐ice reduction in late autumn
Tetsu Nakamura,Tetsu Nakamura,Koji Yamazaki,Koji Yamazaki,Katsushi Iwamoto,Katsushi Iwamoto,Meiji Honda,Yasunobu Miyoshi,Yasunobu Ogawa,Jinro Ukita +9 more
TL;DR: In this paper, a high-top atmospheric general circulation model (AGCM for Earth Simulator, AFES version 4.1) was used to simulate the atmospheric response to observed sea-ice anomalies and found that the recent Arctic sea ice reduction results in cold winters in mid-latitude continental regions, which are linked to an anomalous circulation pattern similar to the negative phase of AO/NAO with an increased frequency of large negative AO events.
Journal ArticleDOI

TL;DR: In this paper, the stratospheric climate and variability from simulations of sixteen chemistry-climate models is evaluated and a wide spread in model performance for most diagnostics with systematic biases in many, and poorer performance in the Southern Hemisphere than in the Northern Hemisphere (NH).

TL;DR: The second round of the Chemistry-Climate Model Validation (CCMVal-2) activity as mentioned in this paper was the most recent activity to provide reliable projections of stratospheric ozone and its impact on climate.
