![]() To do this, it uses the presence of a BWER in reflectivity and atmospheric rotation picked up by Doppler weather radar. The ones capable of producing a tornado are flagged by red or yellow cylinders according to the strength of the vortex as defined by the tornado vortex signature criteria similar to those the National Weather Service uses. Storms are classified according to certain criteria and ranked. VIPIR automatically locates thunderstorms over the radar coverage area using algorithms analyzing the water content of each storm, its motion and wind fields. Included in VIPIR are algorithms that analyze precipitation data in order to find signatures of severe thunderstorms, accumulation of rain or snow, and other weather patterns of interest. It is used by television meteorologists to give a comprehensive view of weather, in particular severe weather events. VIPIR images can be constructed from multiple sources, including Doppler weather radar and NEXRAD. If imagery is zoomed in at an adequate range, actual weather satellite data can be superimposed. The result of this process is a three-dimensional image of the storm, which may be rotated and viewed from any angle. This data can be manipulated in a three-dimensional view by VIPIR. WSR-88D, or NEXRAD, Doppler weather radars scan at various elevations, creating a volume scan. This software allows improved analysis of radar data for private users, in particular television stations, similar to the Weather Decision Support System program used by the National Weather Service.
