California Wintertime Precipitation Bias in Regional and Global Climate Models
Publisher: American Meteorological Society
Abstract: In this paper, wintertime precipitation from a variety of observational datasets, regional climate models (RCMs), and general circulation models (GCMs) is averaged over the state of California and compared. Several averaging ...
Response of a Subtropical Stratocumulus-Capped Mixed Layer to Climate and Aerosol Changes
Publisher: American Meteorological Society
Abstract: In this paper, an idealized framework based on a cloud-topped mixed layer model is developed for investigating feedbacks between subtropical stratocumulus (Sc) and global warming. The two principal control parameters are ...
Large Eddy Simulation of the Diurnal Cycle in Southeast Pacific Stratocumulus
Publisher: American Meteorological Society
Abstract: This paper describes a series of 6-day large eddy simulations of a deep, sometimes drizzling stratocumulus-topped boundary layer based on forcings from the East Pacific Investigation of Climate (EPIC) 2001 field campaign. ...
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 ...
Mixed-Layer Budget Analysis of the Diurnal Cycle of Entrainment in Southeast Pacific Stratocumulus
Publisher: American Meteorological Society
Abstract: Mixed-layer budgets of boundary layer mass, moisture, and liquid water static energy are estimated from 6 days of data collected at 20°S, 85°W (a region of persistent stratocumulus) during the East Pacific Investigation ...
Addressing Interdependency in a Multimodel Ensemble by Interpolation of Model Properties
Publisher: American Meteorological Society
Abstract: he diverse set of Earth system models used to conduct the CMIP5 ensemble can partly sample the uncertainties in future climate projections. However, combining those projections is complicated by the fact that models developed ...
A Representative Democracy to Reduce Interdependency in a Multimodel Ensemble
Publisher: American Meteorological Society
Abstract: he collection of Earth system models available in the archive of phase 5 of CMIP (CMIP5) represents, at least to some degree, a sample of uncertainty of future climate evolution. The presence of duplicated code as well as ...
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 ...
