We examined the dependence of the EEJ on solar activity, represented by the 10.7 cm solar radio flux (F10.7). For this analysis, we used a new equatorial electrojet index, EUEL, provided by the MAGDAS/CPMN network in the Southeast Asia sector for the year 2011. Using a two-station method, the EEJ strength was calculated as the difference between the EUEL index of the dip equator station and the EUEL index of the off-dip equator station located outside the narrow channel (±3°in latitudinal range) of the EEJ band. The relationship between the EEJ component and the F10.7 index was then examined using power spectrum and correlation analyses. We found approximate 24-day and 28-day periodicities in the EEJ component, which are in phase with F10.7 variations. On the other hand, the daily values of EEJ showed low correlation with the daily F10.7 variations during the study period.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009708","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.510.535/.537","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Planetary Sciences, Graduate School of Sciences, 33 Kyushu University, 6-10-1 Hakozaki, Higashi-ku, Fukuoka 812-8581."},{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Planetary Sciences, Faculty of Sciences, 33 Kyushu University, 6-10-1 Hakozaki, Higashi-ku, Fukuoka 812-8581."},{"subitem_text_language":"en","subitem_text_value":"International Center for Space Weather Science and Education (ICSWSE), Kyushu University 53, 6-10-1 Hakozaki, Higashi-ku, Fukuoka 812-8581."},{"subitem_text_language":"en","subitem_text_value":"International Center for Space Weather Science and Education (ICSWSE), Kyushu University 53, 6-10-1 Hakozaki, Higashi-ku, Fukuoka 812-8581."}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"九州大学大学院理学府地球惑星科学専攻"},{"subitem_text_value":"九州大学大学院理学研究院地球惑星科学部門"},{"subitem_text_value":"九州大学国際宇宙天気科学・教育センター."},{"subitem_text_value":"九州大学大学院理学研究院地球惑星科学部門."}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-11-29"}],"displaytype":"detail","filename":"KJ00008950839.pdf","filesize":[{"value":"334.9 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00008950839","url":"https://nipr.repo.nii.ac.jp/record/9708/files/KJ00008950839.pdf"},"version_id":"910f974f-a7fc-4237-a8e9-f393d5f29e5a"}]},"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":"東南アジア地域における赤道ジェット電流の太陽活動依存性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東南アジア地域における赤道ジェット電流の太陽活動依存性"},{"subitem_title":"Equatorial electrojet dependence on solar activity in the Southeast Asia sector","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1170"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-11-29"},"publish_date":"2013-11-29","publish_status":"0","recid":"9708","relation_version_is_last":true,"title":["東南アジア地域における赤道ジェット電流の太陽活動依存性"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:23:31.702775+00:00"}
