A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar ...
In 2017, Weather Underground removed support for "Storm," in favor of the "Storm Radar" app released by The Weather Channel Interactive in June 2017. [31] On December 31, 2018, Weather Underground ceased offering its popular application programming interface (API) for weather data, further reducing the breadth of its services. [32]
The result of this process is a three-dimensional image of the storm, which may be rotated and viewed from any angle. If imagery is zoomed in at an adequate range, actual weather satellite data can be superimposed. VIPIR images can be constructed from multiple sources, including Doppler weather radar and NEXRAD. [3]
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.).
A radar tracker is a component of a radar system, or an associated command and control (C2) system, that associates consecutive radar observations of the same target into tracks. It is particularly useful when the radar system is reporting data from several different targets or when it is necessary to combine the data from several different ...
Mesonets, along with remote sensing solutions (data assimilation of weather radar, weather satellites, wind profilers), allow for much greater temporal and spatial resolution in a forecast model. As the atmosphere is a chaotic nonlinear dynamical system (i.e. subject to the Butterfly effect ), this increase in data increases understanding of ...
It can be transcluded on pages by placing {{Weather Underground}} below the standard article appendices. Initial visibility This template's initial visibility currently defaults to autocollapse , meaning that if there is another collapsible item on the page (a navbox, sidebar , or table with the collapsible attribute ), it is hidden apart from ...
