| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Rain attenuation characteristics due to typhoon passage are discussed using the Ku band satellite signal observations conducted in Neyagawa, Osaka, from 1988 to 2019. The ratio of hourly rain attenuation to rainfall rate is found to be largely enhanced as the typhoon passes the east side of the station. The equivalent path lengths averaged over each rainfall event become larger in the case of east side typhoon passage, while they become smaller in the case of west side passage. As compared with the ground wind velocities obtained from nearby AMeDAS, the equivalent path lengths become larger as the wind directions approach the opposite of the satellite azimuth angle, while they become smaller as the wind directions nears the satellite azimuth angle. Thus, in this study, the rain attenuation characteristics are for the first time proved to be largely affected by the direction of typhoon passage and the ground wind velocities. | |
