Abstract
AbstractPurpose of ReviewStationary waves are planetary-scale longitudinal variations in the time-averaged atmospheric circulation.Here, we consider the projected response of Northern Hemisphere stationary waves to climate change in winter and summer. Wediscuss how the response varies across different metrics, identify robust responses, and review proposed mechanisms.Recent FindingsClimate models project shifts in the prevailing wind patterns, with corresponding impacts on regional precip-itation, temperature, and extreme events. Recent work has improved our understanding of the links between stationary waves andregional climate and identified robust stationary wave responses to climate change, which include an increased zonal lengthscalein winter, a poleward shift of the wintertime circulation over the Pacific, a weakening of monsoonal circulations, and an overallweakening of stationary wave circulations, particularly their divergent component and quasi-stationary disturbances.SummaryNumerous factors influence Northern Hemisphere stationary waves, and mechanistic theories exist for only a fewaspects of the stationary wave response to climate change. Idealized studies have proven useful for understanding the climateresponses of particular atmospheric circulation features and should be a continued focus of future research.
