2018 DTC Community Unified Forecast System Test Plan and Metrics Workshop

April 30, 2018

The Developmental Testbed Center (DTC) is pleased to announce an upcoming community workshop on Numerical Weather Prediction test plan and metrics for model validation and verification.

Now available: Agenda | Registration | Logistics

The workshop, to take place at the NCWCP in College Park, MD, will be held for two and a half days prior to the NGGPS Strategic Implementation Planning (SIP) meeting at the same location. The major goal of this workshop is to develop a community test plan with common validation and verification metrics for the emerging Unified Forecast System (UFS). When complete, the plan will serve as a guide for the NWP community for testing and validating new developments for the UFS models and components, and for verifying the UFS for both historical and real-time forecasts using observations and analyses, through standardized hierarchical testing. While metrics for all spatial and temporal scales for NWP models will be open for discussion at the workshop, emerging topics such as the verification of Convective Allowing Models, coupled earth system models, and ensemble systems will be emphasized.

The full two days of the workshop (July 30th - July 31st) will utilize mornings for participant presentations and short discussion periods, with the afternoons focusing on editing plan documents in various topic-based breakout sessions. Participants are requested to bring a laptop or tablet to assist in the real-time development of planning documents during the breakout sessions. A wrap-up session will be held on the final morning (August 1st). NGGPS Strategic Implementation Planning (SIP) meeting attendees are encouraged to participate in the Test Plan and Metrics wrap-up session prior to their meeting starting the afternoon of August 1st.

2018 Hurricane WRF Tutorial

Autumn 2017

The DTC is pleased to announce that registration is now open for the 2018 Hurricane WRF (HWRF) tutorial to be held 23–25 January 2018 at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, MD. Registration, a draft agenda, and information about hotel accommodations and other logistics can be found on our tutorial website:

2018 HWRF tutorial

The HWRF tutorial will be a three-day event organized by the Developmental Testbed Center (DTC) and by the NOAA Environmental Modeling Center (EMC). The Hurricane Weather Research and Forecast system (HWRF) is a coupled atmosphere-ocean model suitable for tropical cyclone (TC) research and forecasting in all Northern and Southern Hemisphere ocean basins.

Tutorial participants can expect to hear lectures on all aspects of HWRF, including model physics and dynamics, nesting, initialization, coupling with the ocean, postprocessing, and vortex tracking. Additionally, enrichment lectures on HWRF's multistorm capability, TC verification, HWRF ensemble system, and NCEP's future plans for TC numerical weather prediction will be presented. Practical sessions will give tutorial participants hands-on experience in running HWRF.

We look forward to seeing you in College Park. If you have any questions, please do not hesitate to contact:

Physics Workshop The DTC and NOAA will convene a workshop entitled ‘Parameterization of moist process for next-generation numerical weather prediction models’ on January 27-29 2015 at the NOAA Center for Weather and Climate Prediction in College Park, MD.

The workshop is intended to stimulate the development of moist process parameterization for the Next- Generation Global Prediction System (NGGPS) and similar global models at scales and resolutions ranging from synoptic- to convection-permitting. The theme of the workshop will also be highly relevant to current and future generation regional and mesoscale models. Observational, modeling and theoretical perspectives will be addressed.
