TL;DR: The Canadian Earth System Model version 5 (CanESM5) as mentioned in this paper is a global model developed to simulate historical climate change and variability, to make centennial-scale projections of future climate, and to produce initialized seasonal and decadal predictions.

TL;DR: The Stratosphere-troposphere Processes And their Role in Climate (SPARC) Reanalysis Intercomparison Project (S-RIP) is a coordinated activity to compare reanalysis data sets using a variety of key diagnostics.

TL;DR: In this article, the authors compared a new classification technique of weak vortex events, based on the distribution of potential vorticity, with that of an existing technique and demonstrated that the subdivision of such events into vortex displacements and vortex splits has important implications for tropospheric weather patterns on weekly to monthly time scales.

TL;DR: A review of the modeling and observational analyses of the quasi-biennial oscillation (QBO)-vortex coupling has appeared in the literature, and update the observational record is provided in this article.

TL;DR: In this paper, a multi-model ensemble of coupled atmosphere-ocean general circulation models (GCMs) obtained from the Coupled Model Intercomparison Project Phase 5 (CMIP5) was examined in a Northern Hemisphere winter (December-January-February) scenario.
