Stratosphere‐troposphere exchange
James R. Holton,Peter H. Haynes,Michael E. McIntyre,Anne R. Douglass,Richard B. Rood,Leonhard Pfister +5 more
TL;DR: The role of wave-induced forces in the extratropical overworld is discussed in this paper, where the authors focus on the role of waves and eddies in the overworld overworld and show that the global exchange rate is determined by details of near-tropopause phenomena such as penetrative cumulus convection or small-scale mixing associated with upper level fronts and cyclones.
Journal ArticleDOI

TL;DR: The quasi-biennial oscillation (QBO) as discussed by the authors dominates the variability of the equatorial stratosphere (∼16-50 km) and is easily seen as downward propagating easterly and westerly wind regimes, with a variable period averaging approximately 28 months.
Journal ArticleDOI
On the “Downward Control” of Extratropical Diabatic Circulations by Eddy-Induced Mean Zonal Forces
TL;DR: In this paper, the authors considered a zonally symmetric model of the middle atmosphere subject to a given quasi-steady zonal force F, conceived to be the result of irreversible angular momentum transfer due to the upward propagation and breaking of Rossby and gravity waves together with any other dissipative eddy effects that may be relevant.
Journal ArticleDOI
On the Evolution of Vorticity and Potential Vorticity in the Presence of Diabatic Heating and Frictional or Other Forces
TL;DR: In this article, it is shown that neither diabatic heating, nor frictional forces, nor external forces such as might be used to model gravity-wave drag, can bring about any net transport or Rossby-Ertel potential vorticity (PV) across an isotropic surface.
Journal ArticleDOI
Effective diffusivity as a diagnostic of atmospheric transport: 1. Stratosphere
Peter H. Haynes,Emily Shuckburgh +1 more
TL;DR: In this paper, the authors analyzed the transport and mixing properties of the isentropic flow in the lower and middle stratosphere by using observed winds to advect a tracer on isentropy surfaces in the range 400-850 K.
