Numerical analysis is performed by using a simple box model, taking account of the anisotropically conducting ionosphere and the insulating atmosphere. Owing to limited capacity of a computer, the effect of the ionospheric Hall current is discussed. We obtained the following results : (1) The mode conversion effect due to the Hall current gives rise to resonant coupling when the azimuthal wave number is zero (the azimuthal direction is referred to the direction perpendicular to the plane of the box model). (2) The Alfven mode perturbation is enhanced along the resonant field line but in the case of the fast magnetosonic mode the enhancement does not occur.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004141","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756224","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":"Meteorological College"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1993-02-01"}],"displaytype":"detail","filename":"KJ00000036072.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036072","url":"https://nipr.repo.nii.ac.jp/record/4141/files/KJ00000036072.pdf"},"version_id":"2478185e-7a2b-40f3-bc54-9c30b14b918b"}]},"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":"Coupled magnetohydrodynamic oscillations in the magnetsphere-iono-sphere system -Hall current effect-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Coupled magnetohydrodynamic oscillations in the magnetsphere-iono-sphere system -Hall current effect-"}]},"item_type_id":"1","owner":"4","path":["542"],"pubdate":{"attribute_name":"公開日","attribute_value":"1993-02-01"},"publish_date":"1993-02-01","publish_status":"0","recid":"4141","relation_version_is_last":true,"title":["Coupled magnetohydrodynamic oscillations in the magnetsphere-iono-sphere system -Hall current effect-"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:23:21.451774+00:00"}
