RISThe 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 ...
Interpretation of Factors Controlling Low Cloud Cover and Low Cloud Feedback Using a Unified Predictive Index
Publisher: American Meteorological Society
Abstract: AbstractThis paper reports on a new index for low cloud cover (LCC), the estimated cloud-top entrainment index (ECTEI), which is a modification of estimated inversion strength (EIS) and takes into account a cloud-top ...
The Relationship between Land–Ocean Surface Temperature Contrast and Radiative Forcing
Publisher: American Meteorological Society
Abstract: revious work has demonstrated that observed and modeled climates show a near-time-invariant ratio of mean land to mean ocean surface temperature change under transient and equilibrium global warming. This study confirms ...
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 ...
Mechanisms of the Negative Shortwave Cloud Feedback in Middle to High Latitudes
Publisher: American Meteorological Society
Abstract: ncreases in cloud optical depth and liquid water path (LWP) are robust features of global warming model simulations in high latitudes, yielding a negative shortwave cloud feedback, but the mechanisms are still uncertain. ...
Interactions between Hydrological Sensitivity, Radiative Cooling, Stability, and Low-Level Cloud Amount Feedback
Publisher: American Meteorological Society
Abstract: AbstractLow-level cloud feedbacks vary in magnitude but are positive in most climate models, due to reductions in low-level cloud fraction. This study explores the impact of surface evaporation on low-level cloud fraction ...
Structural Similarities and Differences in Climate Responses to CO2 Increase between Two Perturbed Physics Ensembles
Publisher: American Meteorological Society
Abstract: The equilibrium climate sensitivity (ECS) of the two perturbed physics ensembles (PPE) generated using structurally different GCMs, Model for Interdisciplinary Research on Climate (MIROC3.2) and the Third Hadley Centre ...
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 ...
How Well Do We Understand and Evaluate Climate Change Feedback Processes?
Publisher: American Meteorological Society
Abstract: Processes in the climate system that can either amplify or dampen the climate response to an external perturbation are referred to as climate feedbacks. Climate sensitivity estimates depend critically on radiative feedbacks ...
