Particle data from Polar shows that during the storm main phase protons with medium energies (20-80 keV) contribute more to the total ring current energy than the high energy protons (80-200 keV) whereas during the recovery phase high energies dominate. We trace protons with arbitrary pitch angles numerically in the guiding center approximation taking into account charge-exchange losses. Tracing is performed in the large-scale and smaller-scale time-dependent magnetic and electric field models. We model the substorm activity by several electric field pulses at times of the substorm onsets. It is shown that impulsive electric fields associated with substorms are effective in the proton transport and energization to higher energies more than 100 keV in the storm time ring current.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006386","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":"AA11397422","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":"Finnish Meteorological Institute, Geophysical Research Division/University of Helsinki/Finnish Meteorological Institute, Geophysical Research Division/National Institute of Polar Research/National Institute of Polar Research/Boston University, Department of Astronomy"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2004-08-01"}],"displaytype":"detail","filename":"KJ00000729623.pdf","filesize":[{"value":"158.9 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000729623","url":"https://nipr.repo.nii.ac.jp/record/6386/files/KJ00000729623.pdf"},"version_id":"3245716c-c227-487a-ada4-fb92246d823e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ring current","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic storms","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"substorm-associated electric fields","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Evolution of the ring current energy during May 2-4, 1998 magnetic storm","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evolution of the ring current energy during May 2-4, 1998 magnetic storm"}]},"item_type_id":"1","owner":"4","path":["808"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-08-01"},"publish_date":"2004-08-01","publish_status":"0","recid":"6386","relation_version_is_last":true,"title":["Evolution of the ring current energy during May 2-4, 1998 magnetic storm"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:02:09.410336+00:00"}
