The Role of the Stratosphere in Subseasonal to Seasonal Prediction: 2. Predictability Arising From Stratosphere‐Troposphere Coupling (2020, background): “Like the 2018 event, up to two thirds of SSW events are followed by anomalous tropospheric weather patterns that can remain persistent for several weeks (Charlton-Perez et al., 2018; Domeisen, 2019; Karpechko et al., 2017; Simpson et al., 2011; White et al., 2019).”
The Teleconnection of El Niño Southern Oscillation to the Stratosphere (2019, background): “…et al., 2015), the stratospheric anomalies then tend to impact weather at the surface for several weeks to months by increasing the likelihood of a negative phase of the NAO and the NAM (see Figure 6a), although not all SSW events have a surface impact (Karpechko et al., 2017; Kodera et al., 2016).”
The Remarkably Strong Arctic Stratospheric Polar Vortex of Winter 2020: Links to Record‐Breaking Arctic Oscillation and Ozone Loss (2020, background): “Factors that seem to determine whether a given vortex event will influence the troposphere include the persistence and magnitude of stratospheric anomalies, the depth to which anomalies penetrate into the lower stratosphere, and the tropospheric state at the time of the stratospheric event (Charlton”
Predicting Sudden Stratospheric Warming 2018 and Its Climate Impacts With a Multimodel Ensemble (2018, methodology): “This diagnostic is widely used to illustrate stratosphere-troposphere coupling, and it strongly correlates ( r ~ 0.9) with other indices used to represent the Northern Annular Mode (Baldwin & Dunkerton, 1999; Karpechko et al., 2017; Runde et al., 2016).”
