The Warning Decision Training Division (WDTD), known as the Warning Decision Training Branch until April 1, 2015,is one of three training organizations in the NWS Training Division which also includes the Forecast Decision Training Branch and the NWS Training Center. WDTD develops and delivers training on the integrated elements of the warning process within a National Oceanic and Atmospheric Administration (NOAA)/National Weather Service (NWS) forecast office. WDTD instructors develop and deliver a variety of in-residence, teletraining, and on-line asynchronous training content.
The National Weather Service Training Center (NWSTC) provides initial and continuing education to NOAA/NWS employees in the areas of equipment, management, meteorology, hydrology, systems support, and related activities. NWSTC's staff develop and deliver courses in a number of formats including residence classes and workshops, web-based and computer-based self-study tutorials, teletraining, and work aides. It is located in Kansas City, Missouri.
The National Oceanic and Atmospheric Administration is an American scientific agency within the United States Department of Commerce that focuses on the conditions of the oceans, major waterways, and the atmosphere.
With the nationwide implementation of the NEXRAD program, NWS management formed a training group designed to create and teach a course dedicated to the understanding and application of the WSR-88D radar. In the summer of 1989, this training group, called the Operations Training Facility (OTF) was staffed with six meteorologist instructors and a secretary (referred to as the NEXRAD Training Unit, or NTU). This facility was originally part of the NWS Forecast Office in Norman, OK and administered by the Southern Region of the NWS.
In 1991, reorganization of the NWS led to the transfer of administration of NTU staff to the rapidly growing Operational Support Facility (OSF). After the transfer, the NTU/OTF became known as the Operations Training Branch (OTB), which is now known as the Radar Operations Center (ROC). Over the years, the training evolved and matured and eventually the course went from a five-week course taught by staff from UNISYS to an eighteen-day course taught exclusively by OTB instructors. Enrollment increased to the point that OTB staff were teaching three simultaneous classes with 24 students each including students from both NWS and Department of Defense (DoD). By 1993, there were 27 NWS and DoD instructors at OTB. In 1997, the last residence WSR-88D OPS Course was taught. During the seven years of residence classes, 2,525 students completed the OPS course. In 1998, the OTB was awarded the DoC Bronze Medal for the development and delivery of the WSR-88D OPS Course. The course had been recognized by NWS employees as an example of training done right in the NWS Modernization. Budgetary restrictions led OTB staff to start using a new training technique: Teletraining. By utilizing teletraining, and later other distance learning techniques and a one-week workshop, the old OPS course evolved into the Distance Learning Operations Course (DLOC).
The Radar Operations Center (ROC) is a National Weather Service (NWS) unit that coordinates the development, maintenance, and training for the NEXRAD weather radar network. It is located at the National Weather Center (NWC) in Norman, Oklahoma and run by the National Oceanic and Atmospheric Administration (NOAA) in the Department of Commerce with partners at the Department of Defense and the Department of Transportation.
In the fall of 2000, the NWS again transferred administrative control of the Operations Training Branch. This reorganization resulted in a new name, the Warning Decision Training Branch, and a new home in the Continuous Learning Division of the Office of Climate, Water, and Weather Services (OCWWS). As part of this second reorganization, DLOC and other training developed by WDTB transitioned from being "radar-centric" to "warning issuance-centric". In the summer of 2006, WDTB moved into its new home at the National Weather Center (NWC) on the University of Oklahoma (OU) south research campus.
The National Weather Center (NWC), on the campus of the University of Oklahoma, is a confederation of federal, state, and academic organizations that work together to better understand events that take place in Earth's atmosphere over a wide range of time and space scales. The NWC partners give equal attention to applying that understanding to the development of improved observation, analysis, assimilation, display, and prediction systems. The National Weather Center also has expertise in local and regional climate, numerical modeling, hydrology, and weather radar. Members of the NWC work with a wide range of federal, state, and local government agencies to help reduce loss of life and property to hazardous weather, ensure wise use of water resources, and enhance agricultural production. They also work with private sector partners to develop new applications of weather and regional climate information that provide competitive advantage in the marketplace.
The University of Oklahoma (OU) is a public research university in Norman, Oklahoma. Founded in 1890, it had existed in Oklahoma Territory near Indian Territory for 17 years before the two became the state of Oklahoma. In Fall 2018 the university had 31,702 students enrolled, most at its main campus in Norman. Employing nearly 3,000 faculty members, the school offers 152 baccalaureate programs, 160 master's programs, 75 doctorate programs, and 20 majors at the first professional level. David Boren, a former U.S. Senator and Oklahoma Governor, served as the university's president from 1994 to 2018. James L. Gallogly succeeded Boren on July 1, 2018.
Effective at the end of March 2015, NWS headquarters was reorganized and the Warning Decision Training Branch became the Warning Decision Training Division.
NEXRAD or Nexrad is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the Department of Defense. Its technical name is WSR-88D.
WSR-74 radars were Weather Surveillance Radars designed in 1974 for the National Weather Service. They were added to the existing network of the WSR-57 model to improve forecasts and severe weather warnings. Some have been sold to other countries like Australia, Greece, and Pakistan.
WSR-57 radars were the USA's main weather surveillance radar for over 35 years. The National Weather Service operated a network of this model radar across the country, watching for severe weather.
