FACETs workshop, OAR FACETs working group at NSSL
Sept. 23-25, a FACETs post-doc orientation meeting and OAR working group are hosted by OWAQ at NSSL's offices in Norman, Oklahoma. The goal of the workshop is to familiarize post-docs with the project and progress on the project, while coordinating ideas for the future of the project during the working group. FACETs is Forecasting a Continuum of Environmental Threats and is a proposed next-generation framework for communicating hazardous weather information to be utilized and developed by labs throughout OAR.

Measuring the impact of additional instrumentation on the skill of numerical weather prediction models at forecasting wind ramp events during the first Wind Forecast Improvement Project (WFIP)
Grid operators responsible for making decisions on what kind of power generation to use to keep the grid in balance (conventional versus weather dependent, such as wind or solar) need a reliable numerical weather prediction (NWP) model to ensure grid stability. A statistically significant improvement of the ramp event forecast skill is found through the assimilation of the special WFIP data in two different study areas, and variations in model skill between up‐ramp versus down‐ramp events are found.
Progress toward characterization of the atmospheric boundary layer over northern Alabama using observations by a vertically pointing, S-band profiling radar during VORTEX-Southeast
The spatiotemporal variability of the atmospheric boundary layer regulates the atmosphere's ability to generate and sustain severe thunderstorms. Boundary layer evolution poses significant challenges for numerical weather prediction because both its vertical and horizontal inconsistencies are not handled by most operational models. Using a ground-based vertically pointing radar can reveal additional details about the evolution and character of the boundary layer. Researchers developed an algorithm for observations collected during the Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX) by a vertically-pointing radar. The algorithm automatically separated observations of precipitation and non-precipitation, and allows for further identification of important boundary layer features of interest to the VORTEX-SE community.
