The Weather Research and Forecasting ( WRF) Model [1] ( / ˈwɔːrf /) is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software for this.
In 1962 a research team from the United States Weather Bureau's National Severe Storms Project (NSSP) moved from Kansas City, Missouri to Norman, Oklahoma, where, in 1956, the Cornell Aeronautical Laboratory had installed a 3 cm continuous-wave Doppler Weather Surveillance Radar-1957 . This radar was designed to detect very high wind speeds in ...
The Weather Company LLC is a weather forecasting and information technology company that owns and operates weather.com (the website for The Weather Channel), and Weather Underground. From 2016 to 2023, The Weather Company was a subsidiary of the Watson & Cloud Platform business unit of IBM . [2]
Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
Next Generation (NextGen) Network Enabled Weather (NNEW) is a project to develop a 4-dimension (all points, lateral, vertical and time dimensions) weather data cube (4-D Wx Data Cube) from disparate contributors and locations. Description. Weather has a considerable impact on aviation operations.

The US National Center for Atmospheric Research ( NCAR / ˈɛnkɑːr /) [3] is a US federally funded research and development center (FFRDC) managed by the nonprofit University Corporation for Atmospheric Research (UCAR) and funded by the National Science Foundation (NSF). [4] NCAR has multiple facilities, including ...
AWIPS is a complex network of systems that ingests and integrates meteorological, hydrological, satellite, and radar data, and also processes and distributes the data to 135 Weather Forecast Offices (WFOs) and River Forecast Centers (RFCs) nationwide. Weather forecasters utilize the capabilities of AWIPS to make increasingly accurate weather ...
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. [1] The NWC partners give equal attention to applying that ...
