Local time dependence can be seen in the SC occurrence rate and average intensity of CNA increase. The occurrence rate is highest near midday and shows a secondary small peak near midnight. The average intensity is strong in the daytime and also near midnight. A strong absorption occurs at the time of large SC's with high pre-SC AE index. The intensity of CNA increase tends to be stronger as the rise time of CNA is shorter. Furthermore, it tends to be stronger when the absolute value of the ratio of vertical component to horizontal component for magnetic SC preliminary impulse at Syowa Station is smaller.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004060","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 Physics, School of Liberal Arts, Asahi University/Data Analysis Center for Geomagnetism and Spacemagnetism, Faculty of Science, Kyoto University/Data Analysis Center for Geomagnetism and Spacemagnetism, Faculty of Science, Kyoto University/National Institute of Polar Research /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":"1989-11-01"}],"displaytype":"detail","filename":"KJ00000035991.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035991","url":"https://nipr.repo.nii.ac.jp/record/4060/files/KJ00000035991.pdf"},"version_id":"2d5a9da8-045b-45e0-bcb0-37dabbabb521"}]},"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":"Characteristics of CNA associated with geomagnetic sudden commencements","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Characteristics of CNA associated with geomagnetic sudden commencements"}]},"item_type_id":"1","owner":"4","path":["538"],"pubdate":{"attribute_name":"公開日","attribute_value":"1989-11-01"},"publish_date":"1989-11-01","publish_status":"0","recid":"4060","relation_version_is_last":true,"title":["Characteristics of CNA associated with geomagnetic sudden commencements"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:24:22.468369+00:00"}
