• The Remarkably Strong Arctic Stratospheric Polar Vortex of Winter 2020: Links to Record‐Breaking Arctic Oscillation and Ozone Loss (2020, methodology): “We calculate the vertically resolved NAM index using standardized 65–90◦N geopotential height anomalies as motivated by Cohen et al. (2002) and Baldwin and Thompson (2009), multiplied by −1 for consistent phasing with the AO.”
• Tropospheric Precursors of Anomalous Northern Hemisphere Stratospheric Polar Vortices (2009, methodology): “…from that calendar date’s climatology, after a ninth-order 30-day cutoff low-pass Butterworth filter has been applied to smooth 1 A few figures were created using 658N as the southern latitude, which maximizes the correlation with the NAM in Baldwin and Thompson (2009); the differences were minute.”
• Defining Sudden Stratospheric Warmings (2015, background): “…AM UTC anomalies (Baldwin and Dunkerton 2001; Baldwin 2001) or zonal wind anomalies (Limpasuvan et al. 2004); b) zonal-mean geopotential height anomalies (Baldwin and Thompson 2009; Gerber et al. 2010); and c) vertical profiles of polar cap–averaged temperature (Kuroda and Kodera 2004;…”
• The Role of Linear Interference in the Annular Mode Response to Tropical SST Forcing (2010, unknown): “We recall (Cohen et al. 2002; Baldwin and Thompson 2009) that [DZ] averaged poleward of 608N is a proxy for the negative of the NAM in the troposphere and stratosphere.”
• Sudden Stratospheric Warmings (2020, background): “For example, the first EOF of geopotential height anomalies, also known as the “annular mode”, (Baldwin & Dunker-345 ton, 1999, 2001; Baldwin & Thompson, 2009; Gerber et al., 2010) captures mass fluc-346 tuations between the polar cap and extratropics.”
