Intercomparison of Soil Moisture Memory in Two Land Surface Models
Publisher: American Meteorological Society
Abstract: A heavy rain or a dry period can produce an anomaly in soil moisture, and the dissipation of this anomaly may take weeks to months. It is important to understand how land surface models (LSMs) used with atmospheric general ...
AGCM Biases in Evaporation Regime: Impacts on Soil Moisture Memory and Land–Atmosphere Feedback
Publisher: American Meteorological Society
Abstract: Because precipitation and net radiation in an atmospheric general circulation model (AGCM) are typically biased relative to observations, the simulated evaporative regime of a region may be biased, with consequent negative ...
Land Surface Controls on Hydroclimatic Means and Variability
Publisher: American Meteorological Society
Abstract: ydroclimatic means and variability are determined in large part by the control of soil moisture on surface moisture fluxes, particularly evapotranspiration and runoff. This control is examined here using a simple water ...
A Data-Driven Approach for Daily Real-Time Estimates and Forecasts of Near-Surface Soil Moisture
Publisher: American Meteorological Society
Abstract: ASA?s Soil Moisture Active Passive (SMAP) mission provides global surface soil moisture retrievals with a revisit time of 2?3 days and a latency of 24 h. Here, to enhance the utility of the SMAP data, an approach is presented ...
Soil Moisture, Snow, and Seasonal Streamflow Forecasts in the United States
Publisher: American Meteorological Society
Abstract: and surface model experiments are used to quantify, for a number of U.S. river basins, the contributions (isolated and combined) of soil moisture and snowpack initialization to the skill of seasonal streamflow forecasts ...
Multimodel Ensemble Reconstruction of Drought over the Continental United States
Publisher: American Meteorological Society
Abstract: Retrospectively simulated soil moisture from an ensemble of six land surface/hydrological models was used to reconstruct drought events over the continental United States for the period 1920?2003. The simulations were ...
Drought-Induced Warming in the Continental United States under Different SST Regimes
Publisher: American Meteorological Society
Abstract: The U.S. Climate Variability and Predictability (U.S. CLIVAR) Drought Working Group (DWG) recently performed a series of experiments in which a number of AGCMs were forced with different leading patterns of global SST ...
Assimilation of Satellite-Derived Skin Temperature Observations into Land Surface Models
Publisher: American Meteorological Society
Abstract: Land surface (or ?skin?) temperature (LST) lies at the heart of the surface energy balance and is a key variable in weather and climate models. In this research LST retrievals from the International Satellite Cloud Climatology ...
Impact of Subsurface Temperature Variability on Surface Air Temperature Variability: An AGCM Study
Publisher: American Meteorological Society
Abstract: Anomalous atmospheric conditions can lead to surface temperature anomalies, which in turn can lead to temperature anomalies in the subsurface soil. The subsurface soil temperature (and the associated ground heat content) ...
Soil Moisture Initialization Error and Subgrid Variability of Precipitation in Seasonal Streamflow Forecasting
Publisher: American Meteorological Society
Abstract: ffline simulations over the conterminous United States (CONUS) with a land surface model are used to address two issues relevant to the forecasting of large-scale seasonal streamflow: (i) the extent to which errors in soil ...
