Bridges to Operations: Tests Conducted at DTC Lead to Operational Implementation of Innovations in Physics and Data Assimilation in HWRF

Summer 2018 | The Hurricane Weather Research and Forecast system (HWRF) is one of NOAA’s operational models used to predict the track, intensity, and structure of tropical cyclones. Each winter, scientists at NOAA’s Environmental Modeling Center (EMC), the Developmental Testbed Center (DTC), and NOAA’s Hurricane Research Division (HRD) perform testing and evaluation (T&E) on possible changes to the HWRF physics schemes, dynamic core, and data assimilation system that have the potential to improve HWRF predictions. Many of these… Read More

Visitors: Impact of Vertical Advection Schemes of the Hydrometeors on the Simulated Hurricane Structure and Intensity

Visitor: Shaowu Bao

Summer 2018 | Advection is a computationally expensive process in Numerical Weather Prediction (NWP) models. Therefore, time-sensitive operational forecast models sometimes sum up the hydrometeors, including cloud water, rainwater, ice and snow, prior to calling the advection scheme. For this configuration, the model only needs to calculate the advection of the total condensate. However, the impact of such a time-saving technique has not been systematically evaluated. With the release of HWRF 3.9a, a version of the operational HWRF… Read More

Community Connections: 2018 DTC Community Unified Forecast System Test Plans and Metrics Workshop

July 30 - August 1, 2018

Summer 2018 | The 2018 DTC Community Unified Forecast System Test Plan and Metrics Workshop was held at NOAA’s National Center for Weather and Climate Prediction (NCEP) on July 30 - August 1, 2018. The major goal of this workshop was to work towards a community test plan with common validation and verification metrics for the emerging Unified Forecast System (UFS). The plan will serve as a guide for the Numerical Weather Prediction (NWP) community for testing and evaluating new developments for the UFS models and components by… Read More

Lead Story: Keeping up with Model Testing & Evaluation Advances: New Verification Displays

Winter 2014 | As numerical model predictions and functions proliferate and move toward ever higher resolution, verification techniques and procedures must also advance and adapt.

Lead Story: THE 2013 HURRICANE WRF

Summer 2013 | As the 2013 hurricane season continues in the North Atlantic and eastern North Pacific basins, a newly minted HWRF model is providing forecasts for the National Hurricane Center (NHC) on a new machine and with significant code additions. On July 24, the operational HWRF went live on the Weather and Climate Operational Supercomputing System (WCOSS). A research version for testing continues in use on the jet computers at the NOAA ESRL Global Systems Division. New, more efficient code promises to provide… Read More

Lead Story: Mesoscale Model Evaluation Testbed

ASSISTING WITH THE TRANSITION OF PROMISING NWP TECHNIQUES FROM RESEARCH TO OPERATIONS

Spring 2013 | The DTC provides a common framework for researchers to demonstrate the merits of new developments through the Mesoscale Model Evaluation Testbed (MMET). Established in the Fall of 2012, MMET provides initialization and observation data sets for several case studies and week-long extended periods that can be used by the entire numerical weather prediction (NWP) community for testing and evaluation. The MMET data sets also include baseline results generated by the… Read More

Director's Corner: Bill Lapenta

Summer 2013 | Dear Colleagues, The end-to-end modeling systems in the NOAA operational numerical guidance suite are scientifically based, and research results must and do cross the “Valley of Death” into operations. However, the operational and research communities need to make this journey more efficient and cost effective. That’s one reason why we have testbeds like the DTC. During 20 years as a research scientist at NASA, I had the opportunity to work closely… Read More

Director's Corner: Welcome Message by Bill Kuo

Dear Colleagues,

Spring 2013 | Welcome to the first issue of a quarterly newsletter for the Developmental Testbed Center (DTC). The research to operations (R2O) transition in numerical weather prediction (NWP) is a major challenge facing the U.S. meteorological community. It has been recognized that the U.S. has the largest community around the world working on weather research and numerical modeling. Yet, most of these research results do not directly benefit operational NWP. The DTC was established in 2003 with a mission to… Read More

Who's Who: Tim Brown

Winter 2014 | If you still harbor a notion that software engineers live narrow lives, a few minutes with Tim will quickly persuade you otherwise. Between his present 3-year stint with DTC’s hurricane task and graduate school in Perth, Australia, Tim has worked in Toronto with the Ontario Institute for Cancer Research; Australia with the Center for Water Research; Switzerland, the UK and Antarctica. He declines to speculate where his next career move might take him. In Boulder,… Read More

Who's Who: John Halley Gotway

Spring 2013 | If you’ve submitted a question to the MET help desk, or attended a MET tutorial, there’s a very good chance that you already know John Halley Gotway. John joined NCAR’s Research Applications Laboratory (RAL) as a software developer in 2004 and has been contributing to the verification efforts within RAL and the DTC. John’s background is in mathematics. He worked in Los Angeles at Northrop Grumman, before NCAR and the Rockies drew him to Colorado. His expertise is… Read More
