On the Land Surface–Atmosphere Coupling and Its Impact in a Single-Column Atmospheric Model
Publisher: American Meteorological Society
Abstract: Three versions of the single-column European Centre for Medium-Range Weather Forecasts?Hamburg (ECHAM4) climate model are compared that differ either in the technique of the numerical coupling between land surface and ...
The Diurnal Behavior of Evaporative Fraction in the Soil–Vegetation–Atmospheric Boundary Layer Continuum
Publisher: American Meteorological Society
Abstract: he components of the land surface energy balance respond to periodic incoming radiation forcing with different amplitude and phase characteristics. Evaporative fraction (EF), the ratio of latent heat to available energy ...
Effects of Land Surface–Vegetation on the Boreal Summer Surface Climate of a GCM
Publisher: American Meteorological Society
Abstract: A land surface model (LSM) has been included in the ECMWF Hamburg version 4 (ECHAM4) atmospheric general circulation model (AGCM). The LSM is an early version of the Organizing Carbon and Hydrology in Dynamic Ecosystems ...
African Monsoon Multidisciplinary Analysis: An International Research Project and Field Campaign
Publisher: American Meteorological Society
Abstract: African Monsoon Multidisciplinary Analysis (AMMA) is an international project to improve our knowledge and understanding of the West African monsoon (WAM) and its variability with an emphasis on daily-to-interannual time ...
The First 30 Years of GEWEX
Publisher: American Meteorological Society
The Amma Radiosonde Program and its Implications for the Future of Atmospheric Monitoring Over Africa
Publisher: American Meteorological Society
Abstract: This article describes the upper-air program, which has been conducted as part of the African Monsoon Multidisciplinary Analysis (AMMA). Since 2004, AMMA scientists have been working in partnership with operational agencies ...
AMMA-Model Intercomparison Project
Publisher: American Meteorological Society
Abstract: The African Monsoon Multidisciplinary Analyses-Model Intercomparison Project (AMMA-MIP) was developed within the framework of the AMMA project. It is a relatively light intercomparison and evaluation exercise of both global ...
The AMMA Land Surface Model Intercomparison Project (ALMIP)
Publisher: American Meteorological Society
Abstract: The rainfall over West Africa has been characterized by extreme variability in the last half-century, with prolonged droughts resulting in humanitarian crises. There is, therefore, an urgent need to better understand and ...
Multimodel Estimate of the Global Terrestrial Water Balance: Setup and First Results
Publisher: American Meteorological Society
Abstract: ix land surface models and five global hydrological models participate in a model intercomparison project [Water Model Intercomparison Project (WaterMIP)], which for the first time compares simulation results of these ...
