RISOn the Seasonality of Arctic Black Carbon
Publisher: American Meteorological Society
Abstract: AbstractArctic haze has a distinct seasonal cycle with peak concentrations in winter but pristine conditions in summer. It is demonstrated that the Geophysical Fluid Dynamics Laboratory (GFDL) atmospheric general circulation ...
Constraining Transient Climate Sensitivity Using Coupled Climate Model Simulations of Volcanic Eruptions
Publisher: American Meteorological Society
Abstract: oupled climate model simulations of volcanic eruptions and abrupt changes in CO2 concentration are compared in multiple realizations of the Geophysical Fluid Dynamics Laboratory Climate Model, version 2.1 (GFDL CM2.1). The ...
Influence of Ocean and Atmosphere Components on Simulated Climate Sensitivities
Publisher: American Meteorological Society
Abstract: he influence of alternative ocean and atmosphere subcomponents on climate model simulation of transient sensitivities is examined by comparing three GFDL climate models used for phase 5 of the Coupled Model Intercomparison ...
Stratospheric Ozone and Temperature Simulated from the Preindustrial Era to the Present Day
Publisher: American Meteorological Society
Abstract: esults from the simulation of a coupled chemistry?climate model are presented for the period 1860 to 2005 using the observed greenhouse gas (GHG) and halocarbon concentrations. The model is coupled to a simulated ocean and ...
Sensitivity of the Aerosol Indirect Effect to Subgrid Variability in the Cloud Parameterization of the GFDL Atmosphere General Circulation Model AM3
Publisher: American Meteorological Society
Abstract: he recently developed GFDL Atmospheric Model version 3 (AM3), an atmospheric general circulation model (GCM), incorporates a prognostic treatment of cloud drop number to simulate the aerosol indirect effect. Since cloud ...
Modeling the Interactions between Aerosols and Liquid Water Clouds with a Self-Consistent Cloud Scheme in a General Circulation Model
Publisher: American Meteorological Society
Abstract: To model aerosol?cloud interactions in general circulation models (GCMs), a prognostic cloud scheme of cloud liquid water and amount is expanded to include droplet number concentration (Nd) in a way that allows them to be ...
Declining Aerosols in CMIP5 Projections: Effects on Atmospheric Temperature Structure and Midlatitude Jets
Publisher: American Meteorological Society
Abstract: he effects of declining anthropogenic aerosols in representative concentration pathway 4.5 (RCP4.5) are assessed in four models from phase 5 the Coupled Model Intercomparison Project (CMIP5), with a focus on annual, ...
The GFDL CM3 Coupled Climate Model: Characteristics of the Ocean and Sea Ice Simulations
Publisher: American Meteorological Society
Abstract: his paper documents time mean simulation characteristics from the ocean and sea ice components in a new coupled climate model developed at the NOAA Geophysical Fluid Dynamics Laboratory (GFDL). The GFDL Climate Model version ...
GFDL's CM2 Global Coupled Climate Models. Part I: Formulation and Simulation Characteristics
Publisher: American Meteorological Society
Abstract: The formulation and simulation characteristics of two new global coupled climate models developed at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL) are described. The models were designed to simulate atmospheric and ...
The Dynamical Core, Physical Parameterizations, and Basic Simulation Characteristics of the Atmospheric Component AM3 of the GFDL Global Coupled Model CM3
Publisher: American Meteorological Society
Abstract: he Geophysical Fluid Dynamics Laboratory (GFDL) has developed a coupled general circulation model (CM3) for the atmosphere, oceans, land, and sea ice. The goal of CM3 is to address emerging issues in climate change, including ...
