RISA Conceptual Modeling Study on Biosphere–Atmosphere Interactions and Its Implications for Physically Based Climate Modeling
Publisher: American Meteorological Society
Abstract: This paper presents a conceptual modeling study on the behaviors of terrestrial biosphere?atmosphere systems as they relate to multiple equilibrium states and climate variability, and emphasizes their implications for ...
Impact of Vegetation Feedback on the Response of Precipitation to Antecedent Soil Moisture Anomalies over North America
Publisher: American Meteorological Society
Abstract: Previous studies support a positive soil moisture?precipitation feedback over a major fraction of North America; that is, initial soil moisture anomalies lead to precipitation anomalies of the same sign. To investigate how ...
Toward a Robust Canopy Hydrology Scheme with Precipitation Subgrid Variability
Publisher: American Meteorological Society
Abstract: Representation of the canopy hydrological processes has been challenging in land surface modeling due to the subgrid heterogeneity in both precipitation and surface characteristics. The Shuttleworth dynamic?statistical ...
Impact of Initial Soil Moisture Anomalies on Subsequent Precipitation over North America in the Coupled Land–Atmosphere Model CAM3–CLM3
Publisher: American Meteorological Society
Abstract: To investigate the impact of anomalous soil moisture conditions on subsequent precipitation over North America, a series of numerical experiments is performed using a modified version of the Community Atmosphere Model ...
Impact of Sea Surface Temperature and Soil Moisture on Summer Precipitation in the United States Based on Observational Data
Publisher: American Meteorological Society
Abstract: his study examines the impact of sea surface temperature (SST) and soil moisture on summer precipitation over two regions of the United States (the upper Mississippi River basin and the Great Plains) based on data from ...
Summer Land–Atmosphere Coupling Strength in the United States: Comparison among Observations, Reanalysis Data, and Numerical Models
Publisher: American Meteorological Society
Abstract: his study examines the land?atmosphere coupling strength during summer over subregions of the United States based on observations [Climate Prediction Center (CPC)?Variable Infiltration Capacity (VIC)], reanalysis data ...
Quantifying the Strength of Soil Moisture–Precipitation Coupling and Its Sensitivity to Changes in Surface Water Budget
Publisher: American Meteorological Society
Abstract: This paper presents a new index to quantify the strength of soil moisture?precipitation coupling in AGCMs and explores how the soil moisture?precipitation coupling in Community Atmosphere Model version 3 (CAM3)?Community ...
Integrating Remote Sensing Data on Evapotranspiration and Leaf Area Index with Hydrological Modeling: Impacts on Model Performance and Future Predictions
Publisher: American Meteorological Society
Abstract: sing the Connecticut River basin as an example, this study assesses the extent to which remote sensing data can help improve hydrological modeling and how it may influence projected future hydrological trends. The dynamic ...
Use of ENSO Information in Medium- and Long-Range Forecasting of the Nile Floods
Publisher: American Meteorological Society
Abstract: The natural variability in the annual flow of the Nile is significantly regulated by the El Niño?Southern Oscillation (ENSO). In this paper, several sources of information are combined, including ENSO, rainfall over Ethiopia, ...
Role of Soil Moisture Feedback in the Development of Extreme Summer Drought and Flood in the United States
Publisher: American Meteorological Society
Abstract: his study tackles the contribution of soil moisture feedback to the development of extreme summer precipitation anomalies over the conterminous United States using a regional climate model. The model performs well in ...
