Even at the polar station, Syowa, the Pi 2 component is clearly detected on hissagrams which are obtained by reproducing the original ULF signals by an FM tape recorder with a speed-up ratio of as much as 2×10^4. Based on summarized morphological characteristics of Pi 2, we confirmed the odd mode model of Pi 2 that the fundamental odd mode Alfven wave along a field line anchored in the midnight auroral oval is observed on the earth's surface as Pi 2. A rapid changing of the tail field configuration at the time of substorm onset is suggested.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008136","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":"Onagawa Magnetic Observatory and Geophysical Institute, Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Onagawa Magnetic Observatory and Geophysical Institute, Tohoku University"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東北大学理学部付属女川地磁気観測所"},{"subitem_text_value":"東北大学理学部付属女川地磁気観測所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1980-02-01"}],"displaytype":"detail","filename":"KJ00002477196.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002477196","url":"https://nipr.repo.nii.ac.jp/record/8136/files/KJ00002477196.pdf"},"version_id":"e0dfd693-d336-40c3-8661-15190af06fe2"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"昭和基地のULF波動解析に基づくPe 2型磁気脈動に関するOdd Modeのモデルの検証(d.磁気圏内のULF波動)(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 I)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"昭和基地のULF波動解析に基づくPe 2型磁気脈動に関するOdd Modeのモデルの検証(d.磁気圏内のULF波動)(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 I)"},{"subitem_title":"Examination of the Odd Mode Model of Pi 2 Based on an Analysis of ULF Signals Received at Syowa Station (d.
