RISIntercomparison of Spatial Interpolation Schemes for Use in Nested Grid Models
Publisher: American Meteorological Society
Abstract: Two geometrical and two advection-equivalent spatial interpolation schemes were tested in providing lateral boundary conditions to a nested grid domain. Geometric interpolation schemes used in this study are a zeroth- order ...
Sensitivities of Summertime Mesoscale Circulations in the Coastal Carolinas to Modifications of the Kain–Fritsch Cumulus Parameterization
Publisher: American Meteorological Society
Abstract: AbstractTwo mesoscale circulations, the Sandhills circulation and the sea breeze, influence the initiation of deep convection over the Sandhills and the coast in the Carolinas during the summer months. The interaction of ...
Development and Evaluation of a Coupled Photosynthesis-Based Gas Exchange Evapotranspiration Model (GEM) for Mesoscale Weather Forecasting Applications
Publisher: American Meteorological Society
Abstract: Current land surface schemes used for mesoscale weather forecast models use the Jarvis-type stomatal resistance formulations for representing the vegetation transpiration processes. The Jarvis scheme, however, despite its ...
Development of the Flux-Adjusting Surface Data Assimilation System for Mesoscale Models
Publisher: American Meteorological Society
Abstract: The flux-adjusting surface data assimilation system (FASDAS) is developed to provide continuous adjustments for initial soil moisture and temperature and for surface air temperature and water vapor mixing ratio for mesoscale ...
Assimilating Surface Data to Improve the Accuracy of Atmospheric Boundary Layer Simulations
Publisher: American Meteorological Society
Abstract: Large errors in atmospheric boundary layer (ABL) simulations can be caused by inaccuracies in the specification of surface characteristics in addition to assumptions and simplifications made in boundary layer formulations ...
Improving High-Resolution Weather Forecasts Using the Weather Research and Forecasting (WRF) Model with an Updated Kain–Fritsch Scheme
Publisher: American Meteorological Society
Abstract: fforts to improve the prediction accuracy of high-resolution (1?10 km) surface precipitation distribution and variability are of vital importance to local aspects of air pollution, wet deposition, and regional climate. ...
Simulation of Convective Initiation during IHOP_2002 Using the Flux-Adjusting Surface Data Assimilation System (FASDAS)
Publisher: American Meteorological Society
Abstract: The Flux-Adjusting Surface Data Assimilation System (FASDAS) uses the surface observational analysis to directly assimilate surface layer temperature and water vapor mixing ratio and to indirectly assimilate soil moisture ...
A Dynamically Computed Convective Time Scale for the Kain–Fritsch Convective Parameterization Scheme
Publisher: American Meteorological Society
Abstract: any convective parameterization schemes define a convective adjustment time scale τ as the time allowed for dissipation of convective available potential energy (CAPE). The Kain?Fritsch scheme defines τ based on an estimate ...
Sensitivity of Regional Oxidant Model Predictions to Prognostic and Diagnostic Meteorological Fields
Publisher: American Meteorological Society
Abstract: Objective analysis and diagnostic methods are used to provide hourly meteorological fields to many air quality simulation models. The viability of using predictions from the Pennsylvania State University?National Center ...
Simulation of Atmospheric Boundary Layer Processes Using Local- and Nonlocal-Closure Schemes
Publisher: American Meteorological Society
Abstract: A soil?vegetation?atmospheric boundary layer model was developed to study the performance of two local-closure and two nonlocal-closure boundary layer mixing schemes for use in meteorological and air quality simulation ...
