The particles are injected into the inner magnetosphere from the near-Earth plasma sheet by a strong inductive electric field due to a dipolarization in association with a substorm. The motion of the particles is traced by the bounce-average approximation under a dipolar magnetic field and the Volland-Stern type convection field. The absolute quantity of a directional differential flux of the particles can be obtained. We can calculate the azimuthal component of the current density and an H-component of the magnetic disturbance at the center of the Earth (Dst^*) induced by the current. In this paper, we examine the formation of the ring current and the magnetic disturbance on the moderate storm occurred on February 13-14,1972. We find that (1) the inductive electric field due to the dipolarization may be one of major contributors to Dst^* on this storm, (2) the steep variations of Dst^* in the main phase cannot reproduced by the inductive electric field model, (3) the intensity of Dst^* is sensitive to the number density in the near-Earth plasma sheet, that is, an enhancement of the number density in the near-Earth plasma sheet may produce the steep and the major variations of Dst^*.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004259","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 Polar Science, The Graduate University for Advanced Studies"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1998-12-01"}],"displaytype":"detail","filename":"KJ00000035962.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035962","url":"https://nipr.repo.nii.ac.jp/record/4259/files/KJ00000035962.pdf"},"version_id":"525881e2-ca40-44e9-abf0-bbf209994aa4"}]},"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":"Simulation on ring current formation: A case study of a storm on February 13, 1972","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simulation on ring current formation: A case study of a storm on February 13, 1972"}]},"item_type_id":"1","owner":"4","path":["548"],"pubdate":{"attribute_name":"公開日","attribute_value":"1998-12-01"},"publish_date":"1998-12-01","publish_status":"0","recid":"4259","relation_version_is_last":true,"title":["Simulation on ring current formation: A case study of a storm on February 13, 1972"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:21:42.146951+00:00"}
