Characteristics of the magnetic field fluctuations are examined by means of the spectral MEM and the minimum variance methods. The dynamic spectrum indicates that the spectral peaks appear in the frequency range from 0.01 to 0.05Hz. The spectral power of the component parallel to the average magnetic field tends to be larger than those perpendicular to the field. The angles between the wave normal vector and the average magnetic field are almost restricted within 60°-90°, i. e., the wave normal vector is directed nearly perpendicular to the magnetic field. Therefore, these characteristics strongly signify that the magnetic field fluctuations in the magnetosheath tend to be compressional mode.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautics and Astronautics, Tokai University"},{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautics and Astronautics, Tokai University"},{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautics and Astronautics, Tokai University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1984-07-01"}],"displaytype":"detail","filename":"KJ00000012224.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012224","url":"https://nipr.repo.nii.ac.jp/record/1591/files/KJ00000012224.pdf"},"version_id":"3f9e8e39-e0f2-445d-a4c7-4d98a3ee7fd9"}]},"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":"Characteristics of magnetic field fluctuations as observed in the magnetosheath","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Characteristics of magnetic field fluctuations as observed in the magnetosheath","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["385"],"pubdate":{"attribute_name":"公開日","attribute_value":"1984-07-01"},"publish_date":"1984-07-01","publish_status":"0","recid":"1591","relation_version_is_last":true,"title":["Characteristics of magnetic field fluctuations as observed in the magnetosheath"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:55:14.574772+00:00"}
