RISAssessment of Snow Cover and Surface Albedo in the ECHAM5 General Circulation Model
Publisher: American Meteorological Society
Abstract: Land surface albedo, snow cover fraction (SCF), and snow depth (SD) from two versions of the ECHAM climate model are compared to available ground-based and remote-sensed climatologies. ECHAM5 accurately reproduces the ...
Radiative Fluxes in the ECHAM5 General Circulation Model
Publisher: American Meteorological Society
Abstract: Radiative fluxes in the ECHAM5 general circulation model (GCM) are evaluated using both surface and satellite-based observations. The fluxes at the top of the atmosphere (TOA) are generally in good agreement with the ...
Verification of General Circulation Models Applied to the Hamburg University GCM. Part I: Test of Individual Climate States
Publisher: American Meteorological Society
Abstract: One objective of general circulation models is to simulate, e.g., a ?January? which is not distinguishable from observed Januaries. A strategy to verify an individual simulated state is proposed. Its main elements are: ...
The Characteristics of Cloud Fields Associated with Midlatitude Circulation Systems in a General Circulation Model
Publisher: American Meteorological Society
Abstract: Cloud fields and concurrent dynamical structures associated with extratropical cyclones in a general circulation model are investigated with emphasis on the cool season (October?March). An ensemble approach is used for ...
Storm Tracks and Climate Change
Publisher: American Meteorological Society
Abstract: Extratropical and tropical transient storm tracks are investigated from the perspective of feature tracking in the ECHAM5 coupled climate model for the current and a future climate scenario. The atmosphere-only part of the ...
Evaluation of the Hydrological Cycle in the ECHAM5 Model
Publisher: American Meteorological Society
Abstract: This study investigates the impact of model resolution on the hydrological cycle in a suite of model simulations using a new version of the Max Planck Institute for Meteorology atmospheric general circulation model (AGCM). ...
Nonlinear Aspects of the Climate Response to Greenhouse Gas and Aerosol Forcing
Publisher: American Meteorological Society
Abstract: In a series of equilibrium experiments the climate response to present-day radiative forcings of anthropogenic greenhouse gases and aerosol particles is calculated. The study was performed with a model system consisting ...

Validation of General Circulation Model Radiative Fluxes Using Surface Observations
Publisher: American Meteorological Society
Abstract: The surface radiative fluxes of the ECHAM3 General Circulation Model (GCM) with T2 1, T42, and T 106 resolutions have been validated using observations from the Global Energy Balance Archive (GEBA, World Climate Program-Water ...
A Comparison of Satellite Observations and Model Simulations of Column-Integrated Moisture and Upper-Tropospheric Humidity
Publisher: American Meteorological Society
Abstract: Water vapor distributions obtained from the fourth generation ECHAM general circulation model are compared with satellite observations of total precipitable water (TPW) from the Special Sensor Microwave/Imager (SSM/1) and ...
