RISA GCM Parameterization for the Shortwave Radiative Properties of Water Clouds
Publisher: American Meteorological Society
Abstract: A new parameterization is presented for the shortwave radiative properties of water clouds, which is fast enough to be included in general circulation models (GCMs). It employs the simple relationships found by Slingo and ...
U.K. HiGEM: Simulations of Desert Dust and Biomass Burning Aerosols with a High-Resolution Atmospheric GCM
Publisher: American Meteorological Society
Abstract: The atmospheric component of the United Kingdom?s new High-resolution Global Environmental Model (HiGEM) has been run with interactive aerosol schemes that include biomass burning and mineral dust. Dust emission, transport, ...
A 15-year Simulation of the Clear-Sky Greenhouse Effect Using the ECMWF Reanalyses: Fluxes and Comparisons with ERBE
Publisher: American Meteorological Society
Abstract: Results are presented from the project Clear-sky Longwave from ERA (CLERA), in which simulations were performed of clear-sky longwave fluxes and heating rates for the period 1979?93, based on data from the European Centre ...
Influence of Dynamics on the Changes in Tropical Cloud Radiative Forcing during the 1998 El Niño
Publisher: American Meteorological Society
Abstract: Satellite measurements of the radiation budget and data from the U.S. National Centers for Environmental Prediction?National Center for Atmospheric Research reanalysis are used to investigate the links between anomalous ...
Simulation of the Diurnal Cycle of Outgoing Longwave Radiation with an Atmospheric GCM
Publisher: American Meteorological Society
Abstract: Results are presented from an integration of the U.K. Meteorological Office 11-Layer Atmospheric General Circulation Model, with emphasis on the simulation of the diurnal cycle of the outgoing longwave radiation. The model ...
General Circulation Model Calculations of the Direct Radiative Forcing by Anthropogenic Sulfate and Fossil-Fuel Soot Aerosol
Publisher: American Meteorological Society
Abstract: A new radiation code within a general circulation model is used to assess the direct solar and thermal radiative forcing by sulfate aerosol of anthropogenic origin and soot aerosol from fossil-fuel burning. The radiative ...
The Representation of Water Vapor and Its Dependence on Vertical Resolution in the Hadley Centre Climate Model
Publisher: American Meteorological Society
Abstract: Simulations of the Hadley Centre Atmospheric Climate Model version 3, HadAM3, are used to investigate the impact of increasing vertical resolution on simulated climates. In particular, improvements in the representation ...
Water Vapor Feedbacks in the ECMWF Reanalyses and Hadley Centre Climate Model
Publisher: American Meteorological Society
Abstract: Many studies have been made of the water vapor feedback, in both satellite data and climate model simulations. Most infer the magnitude of the feedback from the variability present in geographical distributions of the key ...
U.K. HiGEM: The New U.K. High-Resolution Global Environment Model—Model Description and Basic Evaluation
Publisher: American Meteorological Society
Abstract: This article describes the development and evaluation of the U.K.?s new High-Resolution Global Environmental Model (HiGEM), which is based on the latest climate configuration of the Met Office Unified Model, known as the ...
The Geostationary Earth Radiation Budget Project
Publisher: American Meteorological Society
Abstract: This paper reports on a new satellite sensor, the Geostationary Earth Radiation Budget (GERB) experiment. GERB is designed to make the first measurements of the Earth's radiation budget from geostationary orbit. Measurements ...
