TIDs (large-scale traveling ionospheric disturbances), in the 50-150 min period range, was made by using observations recorded from November 1957 to July 1974 of f_0F2 in f-plots at four ionospheric observatories distributed in Japan. The speeds and the azimuths of the Fourier components of these disturbances were calculated by performing the cross-spectral analysis to provide dispersion characteristics. The range of horizontal phase trace velocities lies between 341 m/s and 976 m/s in a period of 150 min. between 293 m/s and 884 m/s in a period of 75 min and between 256 m/s and 745 m/s in a period of 50 min. The general tendency of the dispersion is such that the horizontal phase trace velocity increases with period. The direction of the wave propagation is mainly southward, and there is another wave group of which the direction of motion is about southwestward. The polar magnetic activity is positively correlated with the horizontal phase trace velocity at 50 and 150 min components.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008163","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.510.535/.537","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Geophysical Institute, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"College of Liberal Arts, Department of the Earth Science, Kyoto University"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"京都大学理学部地球物理学教室"},{"subitem_text_value":"京都大学教養部地学教室"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1980-03-01"}],"displaytype":"detail","filename":"KJ00002477223.pdf","filesize":[{"value":"4.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002477223","url":"https://nipr.repo.nii.ac.jp/record/8163/files/KJ00002477223.pdf"},"version_id":"a71cfaa7-19d8-4bae-abc7-6151ee2720a9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"電離層F2領域における大規模TIDs(f.極域電離層)(第2回極域における電離圏磁気圏総合観測シンポジウム : Part II)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"電離層F2領域における大規模TIDs(f.極域電離層)(第2回極域における電離圏磁気圏総合観測シンポジウム : Part II)"},{"subitem_title":"Large-Scale TIDs in the F2 Region (f.
