RISA Generalized Subsurface Flow Parameterization Considering Subgrid Spatial Variability of Recharge and Topography
Publisher: American Meteorological Society
Abstract: Subsurface flow is an important hydrologic process and a key component of the water budget. Through its direct impacts on soil moisture, it can affect water and energy fluxes at the land surface and influence the regional ...
Sensitivity of Regulated Flow Regimes to Climate Change in the Western United States
Publisher: American Meteorological Society
Abstract: AbstractWater management activities modify water fluxes at the land surface and affect water resources in space and time. Conventional understanding on the role of water management suggests that regulated river flow would ...
A Modeling Study of Irrigation Effects on Surface Fluxes and Land–Air–Cloud Interactions in the Southern Great Plains
Publisher: American Meteorological Society
Abstract: n this study, the authors incorporate an operational-like irrigation scheme into the Noah land surface model as part of the Weather Research and Forecasting Model (WRF). A series of simulations, with and without irrigation, ...
Modeling the Effects of Groundwater-Fed Irrigation on Terrestrial Hydrology over the Conterminous United States
Publisher: American Meteorological Society
Abstract: uman alteration of the land surface hydrologic cycle is substantial. Recent studies suggest that local water management practices including groundwater pumping and irrigation could significantly alter the quantity and ...
The Low-Level Jet over the Southern Great Plains Determined from Observations and Reanalyses and Its Impact on Moisture Transport
Publisher: American Meteorological Society
Abstract: his study utilizes six commonly used reanalysis products, including the NCEP?Department of Energy Reanalysis 2 (NCEP2), NCEP Climate Forecast System Reanalysis (CFSR), ECMWF interim reanalysis (ERA-Interim), Japanese 25-year ...
Uncertainty Analysis of Runoff Simulations and Parameter Identifiability in the Community Land Model: Evidence from MOPEX Basins
Publisher: American Meteorological Society
Abstract: n this study, the authors applied version 4 of the Community Land Model (CLM4) integrated with an uncertainty quantification (UQ) framework to 20 selected watersheds from the Model Parameter Estimation Experiment (MOPEX) ...
Assessing Impacts of PBL and Surface Layer Schemes in Simulating the Surface–Atmosphere Interactions and Precipitation over the Tropical Ocean Using Observations from AMIE/DYNAMO
Publisher: American Meteorological Society
Abstract: ccuracy of turbulence parameterization in representing planetary boundary layer (PBL) processes and surface?atmosphere interactions in climate models is critical for predicting the initiation and development of clouds. ...
Validation of Noah-Simulated Soil Temperature in the North American Land Data Assimilation System Phase 2
Publisher: American Meteorological Society
Abstract: oil temperature can exhibit considerable memory from weather and climate signals and is among the most important initial conditions in numerical weather and climate models. Consequently, a more accurate long-term land ...
Evaluating Global Streamflow Simulations by a Physically Based Routing Model Coupled with the Community Land Model
Publisher: American Meteorological Society
Abstract: ccurately simulating hydrological processes such as streamflow is important in land surface modeling because they can influence other land surface processes, such as carbon cycle dynamics, through various interaction ...
Comparison and Assessment of Three Advanced Land Surface Models in Simulating Terrestrial Water Storage Components over the United States
Publisher: American Meteorological Society
Abstract: o prepare for the next-generation North American Land Data Assimilation System (NLDAS), three advanced land surface models [LSMs; i.e., Community Land Model, version 4.0 (CLM4.0); Noah LSM with multiphysics options (Noah-MP); ...
