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
Atmospheric circulation as a source of uncertainty in climate change projections
TL;DR: For example, this paper found that scientific confidence in climate change effects is much higher for aspects related to global patterns of surface temperature, than for circulation, necessitating a risk-based approach to decision making.
Journal ArticleDOI
Clouds, circulation and climate sensitivity
Sandrine Bony,Bjorn Stevens,Dargan M. W. Frierson,Christian Jakob,Masa Kageyama,Robert Pincus,Robert Pincus,Theodore G. Shepherd,Steven C. Sherwood,A. Pier Siebesma,Adam H. Sobel,Masahiro Watanabe,Mark J. Webb +12 more
TL;DR: In this paper, four central research questions -now tractable through advances in models, concepts and observations -were proposed to accelerate future progress in understanding the interactions between clouds, circulation and climate.
Journal ArticleDOI
Attribution of climate extreme events
TL;DR: The authors suggest that it is more useful to regard the extreme circulation regime or weather event as being largely unaffected by climate change, and question whether known changes in the climate system's thermodynamic state affected the impact of a particular event.
Journal ArticleDOI
Assessment of temperature, trace species, and ozone in chemistry-climate model simulations of the recent past

TL;DR: In this article, simulations of the stratosphere from thirteen coupled chemistry-climate models (CCMs) are evaluated to provide guidance for the interpretation of ozone predictions made by the same CCMs.
