Winter 2015 | The transition of research advances into operations (abbreviated as R2O), particularly those operations involving numerical weather prediction, satellite meteorology, and severe weather forecasting, has always been a major challenge for the atmospheric science community. With a preeminent mission to facilitate R2O in mind, NOAA and NCAR established the DTC in 2003. Since then, the DTC has worked toward this goal in three specific ways:  by providing community support for operational NWP systems, by performing… Read More

Autumn 2013 | As operational centers move inexorably toward ensemble-based probabilistic forecasting, the role of the DTC as a bridge between research and operations has expanded to include testing and evaluation of ensemble forecasting systems. In 2010 the ensemble task area in the DTC was designed with the ultimate goal of providing an environment in which extensive testing and evaluation of ensemble-related techniques developed by the NWP community could be conducted. Because these results should be immediately relevant… Read More

Spring 2018 | As chief of the Model Development Branch (MDB) at NOAA’s Global System Division (GSD), I am honored to work with many of the scientists from the DTC. The DTC has been a vital partner for the development, testing, and evaluation of the Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR) models, and I look forward to continuing this valuable collaboration as the community works together to define and develop the next-generation modeling system.  The work performed in my branch at GSD is strongly linked to the five… Read More

Spring 2016 | Ralph Stoffler, a member of the US government Senior Executive Service, is the USAF Director of Weather, and the USAF Deputy Chief of Staff for Operations. In this capacity, he is responsible for the development of weather and space environmental doctrine, policies, plans, programs, and standards in support of Army and Air Force operations. He is responsible for overseeing and advocating for Air Force weather resources and monitors the execution of the weather program. He is the functional manager for 4… Read More

Winter 2015 | The DTC was established a number of years ago to facilitate the transition of new capabilities in weather forecasting from research to operations (R2O), with a focus on the WRF model. Over the years, many things have changed – for example, the DTC now works with multiple sets of code (WRF, GSI, MET, HWRF, and so on) which will soon include global prediction systems – but that fundamental mission remains the same. The DTC accomplishes its goals through strong connections to the operational and research… Read More

Autumn 2013 | The Air Force Weather Agency (AFWA) has long been a partner with the DTC since its “unofficial” early days of “core testing” (remember those), to its official charter membership signing in September of 2009, to date. Air Force Weather (AFW) recognized early, the essential role this organization could, and would, play in bolstering and mitigating an ever-growing US Air Force resource constrained terrestrial weather RDT&E environment. Further partnering with our NOAA National Centers for Environmental… Read More

Spring 2018 | The long and winding path to becoming an atmospheric scientist began at a young age for Grant, like many atmospheric scientists. He split his childhood years between watching occasional storms develop over the Sandia Mountains of Albuquerque, NM and the frequent passing of MCSs (Mesoscale Convective Systems) and derechos over the forested hills of southwest Missouri. Grant credits his interest in science and math to a string of inspirational teachers from elementary school and onward, but… Read More

Spring 2016 | Circumstances can make it hard to connect with people, and with snowstorms and parent-teacher conferences, catching up with Chunhua Zhou took a few tries. But meeting her and learning about her work in the DTC made the effort worthwhile. Chunhua and her younger brother grew up in central China. While he still lives there and runs a small business, Chunhua went to the University of Hawaii in 2003, receiving her Ph.D. in Meteorology in 2009. Her thesis studies involved the dynamics of the tropical intraseasonal oscillation… Read More

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

Autumn 2013 | In many ways, Hui is the quintessential DTC lead. Stationed at NCEP’s Environmental Modeling Center but spending several weeks a year in Boulder, she lives R2O (data assimilation variety) day in and day out. Besides the frequent commutes, she is a long-distance veteran in another way, with undergraduate and masters’ level education in China, a PhD at Florida State, and now her dual appointment of sorts in DC and Boulder. There was some chance at Nanjing University that she would follow a different career: space science… Read More

Spring 2018 | The  DTC Verification team hosted a MET tutorial at NCAR January 31-February 2, 2018 in association with the semi-annual WRF tutorial. This event was the first in-residence MET tutorial since February 2015. There were 31 registered users and several new DTC staff dropped in for pertinent lectures.  The tutorial included a half day of lectures on verification basics plus two and a half days of presentations focused on many of the MET tools supplemented with practical sessions that demonstrated the tool… Read More
