Journal ArticleDOI
The simulation of SST, sea ice extents and ocean heat transports in a version of the Hadley Centre coupled model without flux adjustments
C. Gordon,C. Cooper,Catherine A. Senior,Helene T. Banks,Jonathan M. Gregory,T. C. Johns,John F. B. Mitchell,Richard Wood +7 more
TL;DR: A new version of the Hadley Centre coupled model (HadCM3) that does not require flux adjustments to prevent large climate drifts in the simulation is presented in this article.
Journal ArticleDOI
A new method for diagnosing radiative forcing and climate sensitivity
Jonathan M. Gregory,Jonathan M. Gregory,William Ingram,M. A. Palmer,Gareth S. Jones,Peter A. Stott,Robert Thorpe,Jason A. Lowe,T. C. Johns,K. D. Williams +9 more
TL;DR: In this paper, a new method for evaluating the radiative forcing, the climate feedback parameter (W m−2 K−1) and hence the effective climate sensitivity from any GCM experiment in which the climate is responding to a constant forcing is presented.
Journal ArticleDOI
Climate response to increasing levels of greenhouse gases and sulphate aerosols
TL;DR: This paper used a coupled ocean-atmosphere general circulation model to simulate past and future climate since the beginning of the near-global instrumental surface-temperature record and include the effects of the scattering of radiation by sulphate aerosols.
Journal ArticleDOI
The second Hadley Centre coupled ocean-atmosphere GCM: model description, spinup and validation
T. C. Johns,Ruth E. Carnell,Jenny F. Crossley,Jonathan M. Gregory,John F. B. Mitchell,Catherine A. Senior,Simon F. B. Tett,Richard Wood +7 more
TL;DR: In this article, a coupled ocean-atmosphere general circulation model (OAGCM) was developed for studies of climate change and results from a hindcast experiment were presented.
Journal ArticleDOI
Anthropogenic climate change for 1860 to 2100 simulated with the HadCM3 model under updated emissions scenarios
T. C. Johns,Jonathan M. Gregory,William Ingram,Colin E. Johnson,A. K. Jones,Jason A. Lowe,John F. B. Mitchell,David L. Roberts,David M. H. Sexton,David Stevenson,Simon F. B. Tett,Margaret J. Woodage +11 more
TL;DR: In this paper, the authors examined the anthropogenically forced climate response over the historical period, 1860 to present, and projected response to 2100, using updated emissions scenarios and an improved coupled model (HadCM3) that does not use flux adjustments.
