This report consists of three separate studies: (1) a radar climatological description of precipitation lines as displayed by the CPS-9, (2) a similar investigation using the APS-15, and (3) the radar characteristics of precipitation lines associated with heavy rainstorms. These investigations were made to supplement the limited knowledge available concerning precipitation lines, with particular attention to severe weather phenomena and heavy rainstorms. Data are presented to describe rainfall line characteristics such as movement, orientation, duration, size, and growth tendencies. It was found that severe weather and heavy rainfall lines were larger, persisted longer, moved faster, and rotated more than other lines.
