RISRepresenting Spatial Subgrid-Scale Precipitation Variability in a GCM
Publisher: American Meteorological Society
Abstract: A method for spatial disaggregation of rainfall to be used within a GCM is presented and the climate sensitivity to its parameters is assessed. The method is based on the assumption of exponential distribution of rainfall ...
The Impact of Grid and Spectral Nudging on the Variance of the Near-Surface Wind Speed
Publisher: American Meteorological Society
Abstract: rid and spectral nudging are effective ways of preventing drift from large-scale weather patterns in regional climate models. However, the effect of nudging on the wind speed variance is unclear. In this study, the impact ...
A Fine-Mesh Land Approach for General Circulation Models and Its Impact on Regional Climate
Publisher: American Meteorological Society
Abstract: Significant land processes occur on spatial scales too fine to be resolved by most current climate models. To address these subgrid-scale processes better, a model is introduced that represents them by a submesh imposed ...
RCCM2–BATS Model over Tropical South America: Applications to Tropical Deforestation
Publisher: American Meteorological Society
Abstract: A multiyear simulation of the global climate uses a revised version of the National Center for Atmospheric Research (NCAR) Community Climate Model Version 2 (CCM2) coupled to the Biosphere?Atmosphere Transfer Scheme (BATS). ...
Wind-Climate Estimation Based on Mesoscale and Microscale Modeling: Statistical–Dynamical Downscaling for Wind Energy Applications
Publisher: American Meteorological Society
Abstract: his paper demonstrates that a statistical?dynamical method can be used to accurately estimate the wind climate at a wind farm site. In particular, postprocessing of mesoscale model output allows an efficient calculation ...
An investigation of the Annual Cycle of Convective Activity over the Tropical Americas
Publisher: American Meteorological Society
Abstract: Outgoing longwave radiation (OLR) is used to describe the annual cycle of convection that resides over the Amazon Basin during austral summer and over Central America and the adjacent waters of the Pacific during austral ...
Forecast of Icing Events at a Wind Farm in Sweden
Publisher: American Meteorological Society
Abstract: his paper introduces a method for identifying icing events using a physical icing model, driven by atmospheric data from the Weather Research and Forecasting (WRF) model, and applies it to a wind park in Sweden. Observed ...
Comparison of Precipitation Observed over the Continental United States to That Simulated by a Climate Model
Publisher: American Meteorological Society
Abstract: This study compares monthly average frequency, intensity, and amount of hourly precipitation simulated by National Center for Atmospheric Research Community Climate Model version 2/Biosphere-Atmosphere Transfer Scheme to ...
Recipes for Correcting the Impact of Effective Mesoscale Resolution on the Estimation of Extreme Winds
Publisher: American Meteorological Society
Abstract: xtreme winds derived from simulations using mesoscale models are underestimated because of the effective spatial and temporal resolutions. This is reflected in the spectral domain as an energy deficit in the mesoscale ...
Extrapolating Satellite Winds to Turbine Operating Heights
Publisher: American Meteorological Society
Abstract: cean wind retrievals from satellite sensors are typically performed for the standard level of 10 m. This restricts their full exploitation for wind energy planning, which requires wind information at much higher levels ...
