Potential Evaporation and Soil Moisture in General Circulation Models
Publisher: American Meteorological Society
Abstract: The parameterization of continental evaporation in many atmospheric general circulation models (GCMS) used for simulation of climate is demonstrably inconsistent with the empirical work upon which the parameterization is ...
Global Modeling of Land Water and Energy Balances. Part I: The Land Dynamics (LaD) Model
Publisher: American Meteorological Society
Abstract: A simple model of large-scale land (continental) water and energy balances is presented. The model is an extension of an earlier scheme with a record of successful application in climate modeling. The most important changes ...
A Model-Based Investigation of Soil Moisture Predictability and Associated Climate Predictability
Publisher: American Meteorological Society
Abstract: Soil moisture predictability and the associated predictability of continental climate are explored as an initial-value problem, using a coupled land?atmosphere model with prescribed ocean surface temperatures. Ensemble ...
Global Modeling of Land Water and Energy Balances. Part II: Land-Characteristic Contributions to Spatial Variability
Publisher: American Meteorological Society
Abstract: Land water and energy balances vary around the globe because of variations in amount and temporal distribution of water and energy supplies and because of variations in land characteristics. The former control (water and ...
The Interplay between Transpiration and Runoff Formulations in Land Surface Schemes Used with Atmospheric Models
Publisher: American Meteorological Society
Abstract: The Project for Intercomparison of Land-surface Parameterization Schemes (PILPS) has shown that different land surface models (LSMs) driven by the same meteorological forcing can produce markedly different surface energy ...
On the Hydrologic Adjustment of Climate-Model Projections: The Potential Pitfall of Potential Evapotranspiration
Publisher: American Meteorological Society
Abstract: Hydrologic models often are applied to adjust projections of hydroclimatic change that come from climate models. Such adjustment includes climate-bias correction, spatial refinement (?downscaling?), and consideration of ...
Sensitivity of the Global Water Cycle to the Water-Holding Capacity of Land
Publisher: American Meteorological Society
Abstract: The sensitivity of the global water cycle to the water-holding capacity of the plant-root zone of continental soils is estimated by simulations using a mathematical model of the general circulation of the atmosphere, with ...
Global Modeling of Land Water and Energy Balances. Part III: Interannual Variability
Publisher: American Meteorological Society
Abstract: The Land Dynamics (LaD) model is tested by comparison with observations of interannual variations in discharge from 44 large river basins for which relatively accurate time series of monthly precipitation (a primary model ...
Weak Simulated Extratropical Responses to Complete Tropical Deforestation
Publisher: American Meteorological Society
Abstract: The Geophysical Fluid Dynamics Laboratory atmosphere?land model version 2 (AM2/LM2) coupled to a 50-m-thick slab ocean model has been used to investigate remote responses to tropical deforestation. Magnitudes and significance ...
Climate Model Assessment of Changes in Winter–Spring Streamflow Timing over North America
Publisher: American Meteorological Society
Abstract: AbstractOver regions where snowmelt runoff substantially contributes to winter?spring streamflows, warming can accelerate snowmelt and reduce dry-season streamflows. However, conclusive detection of changes and attribution ...
