Summer 2014 | Tim Brown-DTC, Qingfu Liu-EMC, Yong Kwon-formerly of EMC, Ligia Bernardet-DTC, Vijay Tallapragada-EMC, and Sam Trahan-EMC some of the HWRF instructors, May 2014, Taipei, Taiwan.
Winter 2014 | As numerical model predictions and functions proliferate and move toward ever higher resolution, verification techniques and procedures must also advance and adapt.
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, he… Read More
Winter 2014 | One function of the DTC has been to archive and maintain important model-related code, and to make it available to operational and research segments of the meteorological community. As Laurie Carson describes it, the code maintenance and support function has important objectives in both O2R and R2O arenas: for the former, providing operational software to the research community, and for the latter, facilitating transfer of research capabilities to operational software packages. DTC’s approach is based on a… Read More
Winter 2014 | During California field exercises of the Hydrometeorological Testbed (HMT), a key objective has been to improve longer-range forecasts of so-called “atmospheric rivers” or ARs (narrow streams of mid- to low-level moisture) and other meteorological patterns that produce very heavy rainfall. During efforts to evaluate model forecasts for these exercises the DTC has explored methods that can provide more meaningful verification than standard scores. One such method represents regions of, say, precipitation in… Read More
Autumn 2014 | An old management adage says that if you need some new task done NOW, ask someone who is already busy. Although she probably cringes to hear it, this applies well to Tara, with an exception: she would first offer to take it on. Her tireless approach to work follows pretty directly from a commitment to accept new challenges in new places. In practice, it has led to twists and turns along the way. After completing her Master’s degree at Colorado State University in aerosol/cloud interactions in marine stratus, her graduate… Read More
Autumn 2014 | Researchers from the DTC plan to provide numerical model runs from a preliminary version of the North American Rapid Refresh Ensemble system (Pre-NARRE) to the Hydrometeorological Testbed of the Weather Prediction Center (HMT/ WPC) during their current Winter Exercise. The DTC Ensemble Task will run the ensemble system (most likely on the NOAA hjet computing system) and post-process some of the results for HMT/WPC. Members of the ensemble (eight in total) will be produced from both WRF/ RUC and NMMB dynamical cores, and will… Read More
Autumn 2014 | The DTC hosted the 5th Community Gridpoint Statistical Interpolation (GSI) Tutorial on July 14-16 of this summer at the NCAR Foothills Laboratory in Boulder, Colorado. One of several outreach events sponsored recently by the DTC, this tutorial was held in collaboration with other major GSI development teams from around the United States. With an ultimate goal of providing operational capabilities to the research community, this series of tutorials has become a primary training resource whereby both operational and research… Read More

Autumn 2014 | As modifications and additions are made to WRF code and released to the community, users often ask, “Is WRF really improving?”
Autumn 2014 | During my first 15 months as the ESRL Global Systems Division Director, I have learned about the DTC and its role in the modeling community. The DTC has made remarkable gains in supporting the WRF model within the community that has contributed to the great success and usage of the model both nationally and internationally. I believe the DTC is unique in how it is funded and operated as a joint effort between NCAR and NOAA, along with partners from the Air Force. It is my observation that there is a significant effort to… Read More
