Geophysical Research Letters, 2023 The dominant pattern of Northern Hemisphere extratropical climate variability is the Northern Annular Mode (NAM), which in wintertime represents the coupling of the stratospheric and tropospheric circulations. The internal variability associated with the

Stratosphere‐troposphere coupling and annular mode variability in chemistry‐climate models [PDF]
Journal of Geophysical Research, 2010 The internal variability and coupling between the stratosphere and troposphere in CCMVal‐2 chemistry‐climate models are evaluated through analysis of the annular mode patterns of variability.

Stratospheric precursor induces wintertime phase reversal of the “warm Arctic-cold Eurasia” pattern [PDF]
Nature CommunicationsRapid Arctic warming has reached 2–4 times the global average, contrasting with the cooling trend in mid-high latitude Eurasia during the 1990s–2010s. A notable phenomenon of the “warm Arctic-cold Eurasia” (WACE) pattern is its frequent phase reversal ...

Journal of Advances in Modeling Earth Systems, 2012 Extreme cold spells over Northern Europe during winter are examined in order to address the question to what degree and in which ways stratospheric dynamics may influence the state of the troposphere.

How do different pathways connect the stratospheric polar vortex to its tropospheric precursors? [PDF]
Weather and Climate Dynamics, 2023 Processes involving troposphere–stratosphere coupling have been identified as important contributors to an improved subseasonal to seasonal prediction in the mid-latitudes.

The stratosphere: a review of the dynamics and variability [PDF]
Weather and Climate Dynamics, 2022 Large-scale, intra-seasonal to inter-annual variability of the stratosphere is reviewed. Much of the variability is dynamical and induced by waves emanating from the troposphere.

How do gravity waves triggered by a typhoon propagate from the troposphere to the upper atmosphere? [PDF]
Atmospheric Chemistry and Physics, 2022 Gravity waves (GWs) strongly affect atmospheric dynamics and photochemistry and the coupling between the troposphere, stratosphere, mesosphere, and thermosphere. In addition, GWs generated by strong disturbances in the troposphere (e.g. thunderstorms and

npj Climate and Atmospheric Science, 2023 Recent studies have suggested that deep Arctic warming, extending from the surface to the upper troposphere, could trigger mid-latitude atmospheric circulation changes, while shallow Arctic warming, confined in the lowermost troposphere, induces ...

On the value of reanalyses prior to 1979 for dynamical studies of stratosphere–troposphere coupling [PDF]
Atmospheric Chemistry and Physics, 2019 Studies of stratosphere–troposphere coupling, particularly those seeking to understand the dynamical processes underlying the coupling following extreme events such as major stratospheric warmings, suffer significantly from the relatively small number of

Stratospheric Nudging And Predictable Surface Impacts (SNAPSI): a protocol for investigating the role of stratospheric polar vortex disturbances in subseasonal to seasonal forecasts [PDF]
Geoscientific Model Development, 2022 Major disruptions of the winter season, high-latitude stratospheric polar vortices can result in stratospheric anomalies that persist for months. These sudden stratospheric warming events are recognized as an important potential source of forecast skill ...
