네야가와에 있는 오사카전기통신대학(OECU)에서 측정한 Ku밴드 위성 전파 신호의 강우 감쇠에서 검출된 시간차를 이용하여 강우 전선 유형별로 강우 지역의 이동 방향과 속도를 추정합니다. 2002년 20월부터 지난 50년간 오사카, 교토 우지에 위치한 지속가능한 인간권 연구소(RISH), 시가현 시가라키에 위치한 교토대학 MU 천문대(MU)에서 관찰한 바 있다. 이러한 방향과 속도는 이들 방향과 잘 일치하는 것으로 나타났다. 일본 기상청이 발표한 일기도의 강우 전선의 움직임에서 직접 얻은 것입니다. 강우지역의 움직임은 한랭전선과 온난전선, 태풍 등 각 강우 유형에 따라 특징적인 방향을 갖는 것으로 나타났다. 현장 다양성 기법의 효과에 대한 수치적 추정은 60-70km 떨어진 세 위치(OECU, RISH, MU) 중 두 현장 사이에서 두 현장이 정렬됨에 따라 강우 감쇠의 공동 누적 시간 비율이 낮아진다는 것을 나타냅니다. 비 지역의 움직임 방향. 이러한 경우 ITU-R 권장 사항과 비교하여 두 사이트 사이에 필요한 거리는 평균적으로 기존 예측의 약 XNUMX~XNUMX%로 줄어들 수 있습니다.

Abstract: Directions and speeds of the motion of rain areas are estimated for each type of rain fronts, using time differences detected in the rain attenuation of the Ku-band satellite radio wave signals that have been measured at Osaka Electro-Communication University (OECU) in Neyagawa, Osaka, Research Institute of Sustainable Humanosphere (RISH) in Uji, Kyoto, and MU Observatory (MU) of Kyoto University in Shigaraki, Shiga, for the past five years since September 2002. These directions and speeds are shown to agree well with those directly obtained from the motion of rain fronts in the weather charts published by Japan Meteorological Agency. The rain area motion is found to have characteristic directions according to each rain type, such as cold and warm fronts or typhoon. A numerical estimate of the effects of site diversity techniques indicates that between two sites among the three locations (OECU, RISH, MU) separated by 20-50 km, the joint cumulative time percentages of rain attenuation become lower as the two sites are aligned along the directions of rain area motion. In such a case, compared with the ITU-R recommendations, the distance required between the two sites may be, on an average, reduced down to about 60-70% of the conventional predictions.
