Winter 2015 | Ming is one of several DTC scientists with cross-Pacific ties, with early roots in central China (near Xian) and school and work experience in Jiangsu (where his parents live), the Nanjing Institute of Meteorology, Beijing, and the University of Oklahoma, where he earned his PhD in 2005. Since 2007 he has been working at ESRL/GSD in Boulder. One of the go-to people for data assimilation work at the DTC and at GSD with the RAP/HRRR, he is called upon not only for development work on data assimilation… Read More

Winter 2015 | The mission of the DTC is to accelerate the rate of transition of new research and development to operational numerical weather prediction models. To that end, the DTC makes NCEP operational models, such as the Hurricane WRF, available to the general community through yearly releases of stable, well-tested, and well-documented codes, which are supported through a help desk. While the DTC has hundreds of registered HWRF users, only a small subset of them actually contribute innovations, raising questions about the… Read More

Winter 2015 | A successful workshop on Parameterization of Moist Processes for Next-Generation Weather Prediction Models was hosted by NOAA and DTC at the NOAA Center for Weather & Climate Prediction (NCWPC) in College Park, MD, Jan 27-29, 2015. A large number of participants from NOAA, the international operational community, and the research community gathered to discuss topics including microphysics, sub-grid scale clouds and turbulence, and deep convection. The first day of the workshop included two keynote presentations and… Read More

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
