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.).
The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar. It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

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 ...
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 ...
Mesoscale meteorology studies weather systems like thunderstorm clusters too small to be resolved by the earliest weather observation networks. The earliest networks of weather observations in the late 1800s and early 1900s could detect the movement and evolution of larger, synoptic-scale systems like high and low-pressure areas.
The first weather satellite to be considered a success was TIROS-1, launched by NASA on April 1, 1960. [5] TIROS operated for 78 days and proved to be much more successful than Vanguard 2. Other early weather satellite programs include the 1962 Defense Satellite Applications Program (DSAP) [6] and the 1964 Soviet Meteor series.
The village has a separate ZIP code (03845) from surrounding communities in the Bartlett/Conway area. Intervale is found along U.S. Route 302 and New Hampshire Route 16 at their intersection with Hurricane Mountain Road, 1.5 miles (2.4 km) north of the center of North Conway.
Governor Mark Gordon of the state of Wyoming posted a warning on Twitter on March 13, advising residents to stay off the roads at all costs during the storm. [24] The Wyoming Department of Transportation (WYDOT) urged motorists to stay off the roads during the snow on March 12, and stated they were ready to deploy snow plows and materials to ...
