Radar, which stands for RAdio Detection And Ranging, has been utilized to detect precipitation, and especially thunderstorms, since the 1940's. Radar enhancements have enabled NWS forecasters to examine storms with more precision. The radars used by the National Weather Service utilize Doppler weather radar principles.

Doppler radar has not always been used for weather radar. Doppler radar came into common use when the Weather Surveillance Radar – 1988 Doppler radar (WSR-88D) was installed in place of the Weather Surveillance Radar – 1974 (WSR-74) and Weather Surveillance Radar – 1957 (WSR-57) radars that were in place until the early 1990s.

So, to observe the inner structures of clouds, vertical radar cross-sections (RHI) are often preferable. Numerous images in this report are presented as RHIs. On the other hand, clouds can be non-uniform in the horizontal direction. So it is evident that a three-dimensional (3D) presentation of radar images is desirable for clouds.
