The first Unified Forecast System (UFS) Users’ Workshop will take place on July 27-29, 2020 tentatively from 11 AM to 4 PM Eastern Time (ET), with the aim to establish an annual forum to exchange scientific ideas, advance education on applying the UFS, to explore ways that UFS is being applied to weather, climate, and related types of prediction, and to convene the full potential of the community to support and improve the UFS. It will feature lively engagement and discussions with diverse groups of participants from across the Weather Enterprise including public and private sectors, academia, and those involved in operations, all of whom share a common interest in delivering the best forecasts to many stakeholders. The workshop is expected to improve communication, transparency, and mutual trust between operational centers and the broader community.
A community-based, coupled Earth modeling system, the UFS, is under active development to support the Weather Enterprise and to be the source system for NOAA's operational numerical weather prediction forecasts. The UFS numerical applications span local to global domains and predictive timescales from sub-hourly analyses to seasonal predictions. The first application released was the UFS Medium-Range Weather (MRW) Application, which targets atmospheric behavior out to approximately two weeks. The release included the Finite-Volume Cubed-Sphere (FV3) dynamical core, the Common Community Physics Package (CCPP) with four supported physics suites, including the current operational and developmental Global Forecast System (GFS) physics suites, pre-processing utilities, the Unified Post Processor (UPP), and a workflow to build and run the global forecast system. To ensure architectural flexibility and portability, the UFS uses modernized software and infrastructure, providing an opportunity for all parties to share and contribute information in a consistent and up-to-date manner.
For the broadest community engagement, the UFS Users’ Workshop will:
Inform the attendees of the most recent updates to the UFS including programmatic and technical status, and perspectives.
Inform the community on the capabilities of the UFS and how the community can contribute to the development and improvement of the UFS.
Showcase experiences related to various aspects of the modeling system (atmosphere, ocean, sea ice, dynamics, physics, data assimilation, verification, etc.) and range of applications (short-term up to seasonal, global, regional, hurricane, air quality, etc.).
Build a platform for the next generation of scientists to become involved with the UFS, providing continued enhancement of the operational forecast system.
Registration is free but required, please register using the registration tab on the right side of the page. All registration fees received previously will be fully refunded.
* Abstract submission is encouraged but not required. Those unfamiliar with UFS who may be interested in learning more and getting involved are welcome to participate.
In this workshop, papers and projects spanning the full range of readiness levels for the following topics will be highly encouraged:
Exercises using all the UFS applications including Short-Range Weather/Convection Allowing, Medium-Range Weather, Hurricane, Subseasonal-to-Seasonal, Coastal, Air Quality, Space Weather, and Marine/Cryosphere
Development and applications of data assimilation, ensemble techniques, modeling, and post processing
Development of model physics and tools for air-quality prediction
Application of physics-based community tools or frameworks, including but not limited to the Common Community Physics Package (CCPP), the Hierarchical Testing Framework (HTF), and Single-Column Models (SCMs)
Process-oriented model verification and evaluation approaches
Research efforts addressing current forecast priorities such as biases in surface temperature (esp. for the Continental U.S.), sea-surface temperature, thermodynamic profiles in the planetary boundary layer (PBL), PBL mixing, initiation of convection, interaction of land and atmosphere, anomalous fast propagation of severe storms, tropical biases including tropical cyclone track forecast and the Madden-Julian Oscillation (MJO), etc.
Research efforts related to forecasting high-impact weather events such as floods, drought, and tropical cyclones
Computational challenges such as leveraging High Performance Computing (HPC) resources and cloud computing
