RISInterannual Variability of Land–Atmosphere Coupling Strength
Publisher: American Meteorological Society
Abstract: ecent studies in the Global Land?Atmosphere Coupling Experiment (GLACE) established a framework to estimate the extent to which anomalies in the land surface state (e.g., soil moisture) can affect rainfall generation and ...
How Much Do Different Land Models Matter for Climate Simulation? Part II: A Decomposed View of the Land–Atmosphere Coupling Strength
Publisher: American Meteorological Society
Abstract: The Global Land?Atmosphere Coupling Experiment (GLACE) built a framework to estimate the strength of the land?atmosphere interaction across many weather and climate models. Within this framework, GLACE-type experiments are ...
Comparison, Validation, and Transferability of Eight Multiyear Global Soil Wetness Products
Publisher: American Meteorological Society
Abstract: The characteristics of eight global soil wetness products, three produced by land surface model calculations, three from coupled land?atmosphere model reanalyses, and two from microwave remote sensing estimates, have been ...
Evaluation of Polar MM5 Simulations of Antarctic Atmospheric Circulation
Publisher: American Meteorological Society
Abstract: Evaluation of a complete annual cycle of nonhydrostatic mesoscale model simulations of the Antarctic atmospheric circulation is presented. The year-long time series are compiled from a series of overlapping short-duration ...
Sensitivity of Land Surface Simulations to the Treatment of Vegetation Properties and the Implications for Seasonal Climate Prediction
Publisher: American Meteorological Society
Abstract: A coupled land?atmosphere climate model is used to investigate the impact of vegetation parameters (leaf area index, absorbed radiation, and greenness fraction) on the simulation of surface fluxes and their potential role ...
Modeled Antarctic Precipitation. Part I: Spatial and Temporal Variability
Publisher: American Meteorological Society
Abstract: Surface snow accumulation is the primary mass input to the Antarctic ice sheets. As the dominant term among various components of surface snow accumulation (precipitation, sublimation/deposition, and snow drift), precipitation ...
Modeling the ENSO Modulation of Antarctic Climate in the Late 1990s with the Polar MM5
Publisher: American Meteorological Society
Abstract: The Polar fifth-generation Pennsylvania State University?NCAR Mesoscale Model (MM5) is employed to examine the El Niño?Southern Oscillation (ENSO) modulation of Antarctic climate for July 1996?June 1999, which is shown to ...
Modeled Antarctic Precipitation. Part II: ENSO Modulation over West Antarctica
Publisher: American Meteorological Society
Abstract: The impacts of the El Niño?Southern Oscillation (ENSO) on the Antarctic region are of special importance in evaluating the variability and change of the climate system in high southern latitudes. In this study, the ENSO ...
Do Global Models Properly Represent the Feedback between Land and Atmosphere?
Publisher: American Meteorological Society
Abstract: The Global Energy and Water Cycle Experiment/Climate Variability and Predictability (GEWEX/CLIVAR) Global Land?Atmosphere Coupling Experiment (GLACE) has provided an estimate of the global distribution of land?atmosphere ...
On the Nature of Soil Moisture in Land Surface Models
Publisher: American Meteorological Society
Abstract: The soil moisture state simulated by a land surface model is a highly model-dependent quantity, meaning that the direct transfer of one model?s soil moisture into another can lead to a fundamental, and potentially detrimental, ...
