The main purpose of this study is to apply the marine radar mounted on the top of a university building to careful observation of the rainstorm. In spite of some differences in the way of using between the meteorological radar and the marine radar, the marine radar is still very useful as a short-range radar. The present study can be summarized as follows: (1) We can detedct the strong rainfall from cumulonimbus clouds nearly over a 45 Km range from the university by a PPI marine radar of 3.2 cm wavelength. (2) The rainfall from stratus clouds is generally weak and in low altitude, so that, the marine radar is sometimes or partly insensitive to this, because the hills surrounding the university hide the lower part of the radar beam. (3) The marine radar can be expected to play an important role in the rainstorm season as a strong senser of the development and movement of thunderstorm cells.
