RISUsing an AGCM to Diagnose Historical Effective Radiative Forcing and Mechanisms of Recent Decadal Climate Change
Publisher: American Meteorological Society
Abstract: n atmospheric general circulation model is forced with observed monthly sea surface temperature and sea ice boundary conditions, as well as forcing agents that vary in time, for the period 1979?2008. The simulations are ...
Cloud Feedbacks, Rapid Adjustments, and the Forcing–Response Relationship in a Transient CO2 Reversibility Scenario
Publisher: American Meteorological Society
Abstract: he Hadley Centre Global Environment Model, version 2?Earth System (HadGEM2-ES) climate model is forced by a 1% yr?1 compound increase in atmospheric CO2 for 140 years, followed by a 1% yr?1 CO2 decrease back to the starting ...
The Dependence of Global Cloud and Lapse Rate Feedbacks on the Spatial Structure of Tropical Pacific Warming
Publisher: American Meteorological Society
Abstract: AbstractAn atmospheric general circulation model (AGCM) is forced with patterns of observed sea surface temperature (SST) change and those output from atmosphere?ocean GCM (AOGCM) climate change simulations to demonstrate ...
A Surface Energy Perspective on Climate Change
Publisher: American Meteorological Society
Abstract: A surface forcing response framework is developed that enables an understanding of time-dependent climate change from a surface energy perspective. The framework allows the separation of fast responses that are unassociated ...
The Dependence of Radiative Forcing and Feedback on Evolving Patterns of Surface Temperature Change in Climate Models
Publisher: American Meteorological Society
Abstract: xperiments with CO2 instantaneously quadrupled and then held constant are used to show that the relationship between the global-mean net heat input to the climate system and the global-mean surface air temperature change ...
Understanding the Rapid Precipitation Response to CO2 and Aerosol Forcing on a Regional Scale
Publisher: American Meteorological Society
Abstract: recipitation exhibits a significant rapid adjustment in response to forcing, which is important for understanding long-term climate change. In this study, fixed sea surface temperature (SST) simulations are used to analyze ...
Contributions of Different Cloud Types to Feedbacks and Rapid Adjustments in CMIP5
Publisher: American Meteorological Society
Abstract: sing five climate model simulations of the response to an abrupt quadrupling of CO2, the authors perform the first simultaneous model intercomparison of cloud feedbacks and rapid radiative adjustments with cloud masking ...
Intermodel Spread in the Pattern Effect and Its Contribution to Climate Sensitivity in CMIP5 and CMIP6 Models
Publisher: American Meteorological Society
Abstract: Radiative feedbacks depend on the spatial patterns of sea surface temperature (SST) and thus can change over time as SST patterns evolve—the so-called pattern effect. This study investigates intermodel differences in the ...
LongRunMIP: Motivation and Design for a Large Collection of Millennial-Length AOGCM Simulations
Publisher: American Meteorological Society
Abstract: We present a model intercomparison project, LongRunMIP, the first collection of millennial-length (1,000+ years) simulations of complex coupled climate models with a representation of ocean, atmosphere, sea ice, and land ...
