RISModified NAM Microphysics for Forecasts of Deep Convective Storms
Publisher: American Meteorological Society
Abstract: AbstractThe Ferrier?Aligo (FA) microphysics scheme has been running operationally in the National Centers for Environmental Prediction (NCEP) North American Mesoscale Forecast System (NAM) since August 2014. It was developed ...
A Comparison of Multiscale GSI-Based EnKF and 3DVar Data Assimilation Using Radar and Conventional Observations for Midlatitude Convective-Scale Precipitation Forecasts
Publisher: American Meteorological Society
Abstract: GSI-based data assimilation (DA) system, including three-dimensional variational assimilation (3DVar) and ensemble Kalman filter (EnKF), is extended to the multiscale assimilation of both meso- and synoptic-scale observation ...
Comparing the Assimilation of Radar Reflectivity Using the Direct GSI-Based Ensemble–Variational (EnVar) and Indirect Cloud Analysis Methods in Convection-Allowing Forecasts over the Continental United States
Publisher: American Meteorological Society
Abstract: AbstractTwo methods for assimilating radar reflectivity into deterministic convection-allowing forecasts were compared: an operationally used, computationally less expensive cloud analysis (CA) scheme and a relatively more ...

A Proposed Model-Based Methodology for Feature-Specific Prediction for High-Impact Weather
Publisher: American Meteorological Society
Abstract: feature-specific forecasting method for high-impact weather events that takes advantage of high-resolution numerical weather prediction models and spatial forecast verification methodology is proposed. An application of ...
An Adaptive Approach for the Calculation of Ensemble Gridpoint Probabilities
Publisher: American Meteorological Society
Abstract: AbstractTraditional ensemble probabilities are computed based on the number of members that exceed a threshold at a given point divided by the total number of members. This approach has been employed for many years in ...
Mesoscale Model Evaluation Testbed (MMET): A Resource for Transitioning NWP Innovations from Research to Operations (R2O)
Publisher: American Meteorological Society
Abstract: wide range of numerical weather prediction (NWP) innovations are under development in the research community that have the potential to positively impact operational models. The Developmental Testbed Center (DTC) helps ...
The POWER Experiment: Impact of Assimilation of a Network of Coastal Wind Profiling Radars on Simulating Offshore Winds in and above the Wind Turbine Layer
Publisher: American Meteorological Society
Abstract: uring the summer of 2004 a network of 11 wind profiling radars (WPRs) was deployed in New England as part of the New England Air Quality Study (NEAQS). Observations from this dataset are used to determine their impact on ...
The Wind Forecast Improvement Project (WFIP): A Public–Private Partnership Addressing Wind Energy Forecast Needs
Publisher: American Meteorological Society
Abstract: he Wind Forecast Improvement Project (WFIP) is a public?private research program, the goal of which is to improve the accuracy of short-term (0?6 h) wind power forecasts for the wind energy industry. WFIP was sponsored by ...
Evaluating and Improving NWP Forecast Models for the Future: How the Needs of Offshore Wind Energy Can Point the Way
Publisher: American Meteorological Society
Abstract: AbstractTo advance the understanding of meteorological processes in offshore coastal regions, the spatial variability of wind profiles must be characterized and uncertainties (errors) in NWP model wind forecasts quantified. ...
