The ratio between the magnetic and electric field perturbations, &lrtri;B_z/μ_oE_x, has a scale-length dependence : the ratio &lrtri;B_z/μ_oE_x decreases with decreasing scale length. B. FORGET et al.(J. Geophys. Res., 96,1843,1991) explained this scale-length dependence using a static model. In this paper, we compare the ratio &lrtri;B_z/μ_oE_x observed by the DE-2 satellite for various spatial scales with the effective Pedersen conductivity Σ_<p, eff> calculated by the method of FORGET et al. The results show that in many cases this model can adequately explain the observed scale-length dependence. However, cases exist in which the difference, &lrtri;B_z/μ_oE_x-Σ_<p, eff>, decreases at about 0.25-1.0s in temporal scales (2-8km in spatial scales). This behavior is explained as being due to Alfven waves.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004142","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":"Department of Geophysics, Faculty of Science, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Research and Development, Tokai University"},{"subitem_text_language":"en","subitem_text_value":"Data Analysis Center for Geomagnetism and Space Magnetism, Faculty of Science, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Goddard Space Flight Center"}]},"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":"KJ00000036073.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036073","url":"https://nipr.repo.nii.ac.jp/record/4142/files/KJ00000036073.pdf"},"version_id":"12bdbb1c-d108-46d5-934c-92985d65f524"}]},"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":"Scale-length dependence of the ratio between the magnetic and electric field perturbations in the ionospheric field-aligned current region","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Scale-length dependence of the ratio between the magnetic and electric field perturbations in the ionospheric field-aligned current region"}]},"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":"4142","relation_version_is_last":true,"title":["Scale-length dependence of the ratio between the magnetic and electric field perturbations in the ionospheric field-aligned current region"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:23:20.537014+00:00"}
