Director's Corner: DTC Transferal of Code, and Certain Tasks and Responsibilities to EPIC
Bill Mahoney
Winter 2022 | The DTC is at an interesting pivot point in its 19-year history as it has the opportunity to redirect its efforts back to its original imperative of advanced numerical weather prediction (NWP) testing and evaluation. This opportunity is due to the establishment of the Earth Prediction Innovation Center (EPIC). As stated in the DTC charter, “The DTC was initiated in 2003 as a means for the NWP community… Read More
Lead Story: Engaging Forecast Community in UFS Model Development: UFS Forecasters Workshops 2020-21
Winter 2022 | With the advent of the Unified Forecast System (UFS), the operational model development at the National Weather Service (NWS) is increasingly becoming a collective effort that includes contributions from multiple NOAA labs, national agencies, and university research groups. The NWS forecasters are the primary stakeholders of the UFS’ operational forecast products, and therefore, continued engagement with them is important for staying abreast of the real-world performance of the model… Read More
Bridges to Operations: A Comprehensive Retrospective Evaluation of the Global Synthetic Weather Radar Products Using METplus
Winter 2022 | Traditional radar product integrity suffers from gaps in coverage over large areas. While some geographical areas are fortunate to have ground- and/or satellite-based radar coverage, most areas around the globe do not have complete coverage from reliable radar networks. The use of radar-based products is advantageous for understanding current weather conditions and how weather systems may evolve over time. Convection and precipitating weather systems often… Read More
Visitors: Physics Process-based Evaluation of the Hurricane Vortex Structure and Size of Tropical Cyclones in HAFS
Visitor: Shaowu Bao
Winter 2022 | The Hurricane WRF (HWRF) has been the US operational hurricane forecast model since 2007. The Hurricane Forecast and Analysis System (HAFS), based on the GFDL Finite-Volume Cubed-Sphere Dynamical Core (FV3), a scalable and flexible dynamical core, is the likely candidate to replace the operational HWRF. HAFS is the focus of a Unified Forecast System - Research to Operations (UFS-R2O) hurricane modeling project and the next generation hurricane forecast system.… Read More
