RISSpatial Heterogeneity of the Soil Moisture Content and Its Impact on Surface Flux Densities and Near-Surface Meteorology
Publisher: American Meteorological Society
Abstract: Using a subgrid distribution for the soil moisture content derived from a macroscale hydrologic model, it is investigated how lateral subgrid variations in the soil moisture content impact both the daily and the seasonal ...
Some Practical Notes on the Parameter kB−1 for Sparse Vegetation
Publisher: American Meteorological Society
Abstract: This paper deals with the parameter kB?1, the logarithm of the ratio between momentum and heat roughness length, of sparsely vegetated surfaces and bare soil. The bare soil surface is included as a reference, since it is ...
Impact of Some Simplifying Assumptions in the New ECMWF Surface Scheme
Publisher: American Meteorological Society
Abstract: Two simplifying assumptions adopted in the current ECMWF surface scheme are explored: a uniform skin temperature for all grid-box fractions with variable latent heat release and a fixed value of an effective heat conductivity ...
Projected Changes in Mean and Extreme Precipitation in Africa under Global Warming. Part I: Southern Africa
Publisher: American Meteorological Society
Abstract: This study investigates likely changes in mean and extreme precipitation over southern Africa in response to changes in radiative forcing using an ensemble of global climate models prepared for the Intergovernmental Panel ...
Boreal Forest Surface Parameterization in the ECMWF Model—1D Test with NOPEX Long-Term Data
Publisher: American Meteorological Society
Abstract: The objective of the present study was to assess the performance and recent improvements of the land surface scheme used operationally in the European Centre for Medium-Range Weather Forecasts (ECMWF) in a Scandinavian ...
Determining Robust Impacts of Land-Use-Induced Land Cover Changes on Surface Climate over North America and Eurasia: Results from the First Set of LUCID Experiments
Publisher: American Meteorological Society
Abstract: he project Land-Use and Climate, Identification of Robust Impacts (LUCID) was conceived to address the robustness of biogeophysical impacts of historical land use?land cover change (LULCC). LUCID used seven atmosphere?land ...
Effect of Anthropogenic Land-Use and Land-Cover Changes on Climate and Land Carbon Storage in CMIP5 Projections for the Twenty-First Century
Publisher: American Meteorological Society
Abstract: he effects of land-use changes on climate are assessed using specified-concentration simulations complementary to the representative concentration pathway 2.6 (RCP2.6) and RCP8.5 scenarios performed for phase 5 of the ...
The Plumbing of Land Surface Models: Benchmarking Model Performance
Publisher: American Meteorological Society
Abstract: he Protocol for the Analysis of Land Surface Models (PALS) Land Surface Model Benchmarking Evaluation Project (PLUMBER) was designed to be a land surface model (LSM) benchmarking intercomparison. Unlike the traditional ...
The Rhône-Aggregation Land Surface Scheme Intercomparison Project: An Overview
Publisher: American Meteorological Society
Abstract: The Rhône-Aggregation (Rhône-AGG) Land Surface Scheme (LSS) intercomparison project is an initiative within the Global Energy and Water Cycle Experiment (GEWEX)/Global Land?Atmosphere System Study (GLASS) panel of the World ...
The Second Phase of the Global Land–Atmosphere Coupling Experiment: Soil Moisture Contributions to Subseasonal Forecast Skill
Publisher: American Meteorological Society
Abstract: he second phase of the Global Land?Atmosphere Coupling Experiment (GLACE-2) is a multi-institutional numerical modeling experiment focused on quantifying, for boreal summer, the subseasonal (out to two months) forecast ...
