Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
While there is a slight chance of rain in the early morning, the chances of a weather delay due to rain will spike significantly at 4 p.m. and 5 p.m. ET, jumping from 24% to 57%.
Radar image animation of an outflow boundary of a storm approaching Tulsa, Oklahoma. The outflow boundary's weak echo moves left-to-right and passes overhead of the Doppler radar station. The outflow produces a gust front that moves ahead of the main thunderstorm. Outflow, in meteorology, is air that flows outwards from a storm system.
NEXRAD or Nexrad (Next-Generation Radar) 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 ...
Ever since meteorological observations on radar were first made widespread, the need for high-temporal resolution and comprehensive volumetric imagery of all three dimensions of weather phenomena has been a very high priority, due in large part to the fact that hazardous weather often happens in the span of seconds, and often in the lowest 1 kilometer of the atmosphere.

Data extrapolation, including development or dissipation, can be used to find the likely location of a moving weather system. The intensity of rainfall from a particular cloud or group of clouds can be estimated, giving a very good indication as to whether to expect flooding, the swelling of a river etc. Depending on the area of built-up space, drainage and land-use in general, a forecast ...
A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.
The ENIAC main control panel at the Moore School of Electrical Engineering operated by Betty Jennings and Frances Bilas. The history of numerical weather prediction began in the 1920s through the efforts of Lewis Fry Richardson, who used procedures originally developed by Vilhelm Bjerknes [1] to produce by hand a six-hour forecast for the state of the atmosphere over two points in central ...
