要約(英語): During winter, at the Shonai Airport located at the northern part of Japan, some low-level turbulences caused by tornadoes and downbursts often interrupt takeoff and landing, which is the main source of economic loss. It is well-known that weather radar system is one of the most useful devices for observing various weather phenomena. However, it is difficult for conventional radar systems (range resolution of several hundred meters and temporal resolution of about 5 min.) to detect small scale phenomena (horizontal scale of several hundred meters and duration of several minutes). We have been developing a meteorological Ku-band broadband radar (BBR) which can detect small scale phenomena with high resolution (range resolution of several meters and temporal resolution of about one minute). We construct the advisory system with the BBR for supporting aircraft operation at this airport, and have a comparison between the BBR data and the Flight Data Recorder (FDR) data.
