Combining Emergent Constraints for Climate Sensitivity
Publisher: American Meteorological Society
Abstract: A method is proposed for combining information from several emergent constraints into a probabilistic estimate for a climate sensitivity proxy Y such as equilibrium climate sensitivity (ECS). The method is based on fitting ...
Preliminary Study of California Wintertime Model Wet Bias
Publisher: American Meteorological Society
Abstract: The Weather Research and Forecasting (WRF) model version 3.0.1 is used in both short-range (days) and long-range (years) simulations to explore the California wintertime model wet bias. California is divided into four ...
CMIP3 Subtropical Stratocumulus Cloud Feedback Interpreted through a Mixed-Layer Model
Publisher: American Meteorological Society
Abstract: arge-scale conditions over subtropical marine stratocumulus areas are extracted from global climate models (GCMs) participating in phase 3 of the Coupled Model Intercomparison Project (CMIP3) and used to drive an atmospheric ...
Evaluating Emergent Constraints on Equilibrium Climate Sensitivity
Publisher: American Meteorological Society
Abstract: AbstractEmergent constraints are quantities that are observable from current measurements and have skill predicting future climate. This study explores 19 previously proposed emergent constraints related to equilibrium ...
Quantifying the Sources of Intermodel Spread in Equilibrium Climate Sensitivity
Publisher: American Meteorological Society
Abstract: his study clarifies the causes of intermodel differences in the global-average temperature response to doubled CO2, commonly known as equilibrium climate sensitivity (ECS). The authors begin by noting several issues with ...
The Sensitivity of Springtime Arctic Mixed-Phase Stratocumulus Clouds to Surface-Layer and Cloud-Top Inversion-Layer Moisture Sources
Publisher: American Meteorological Society
Abstract: n this study, a series of idealized large-eddy simulations is used to understand the relative impact of cloud-top and subcloud-layer sources of moisture on the microphysical?radiative?dynamical feedbacks in an Arctic ...
Physics–Dynamics Coupling in Weather, Climate, and Earth System Models: Challenges and Recent Progress
Publisher: American Meteorological Society
Abstract: AbstractNumerical weather, climate, or Earth system models involve the coupling of components. At a broad level, these components can be classified as the resolved fluid dynamics, unresolved fluid dynamical aspects (i.e., ...
