We identified seven ICMEs between 2010 and 2011 and compared them with 39 events reported in our previous work. We examined 15 fast (V SOHO−V bg\u003e500 km s−1), 25 moderate (0 km s−1≤V SOHO−V bg≤500 km s−1), and 6 slow (V SOHO−V bg\u003c0 km s−1) ICMEs, where V SOHO and V bg are the initial speed of ICMEs and the speed of the background solar wind. For slow ICMEs, we found the following results: i) They accelerate toward the speed of the background solar wind during their propagation and reach their final speed by 0.34±0.03 AU. ii) The acceleration ends when they reach 479±126 km s−1; this is close to the typical speed of the solar wind during the period of this study. iii) When γ 1 and γ 2 are assumed to be constants, a quadratic equation for the acceleration a=−γ 2(V−V bg)|V−V bg| is more appropriate than a linear one a=−γ 1(V−V bg), where V is the propagation speed of ICMEs, while the latter gives a smaller χ 2 value than the former. For the motion of the fast and moderate ICMEs, we found a modified drag equation a=−2.07×10−12(V−V bg)|V−V bg|−4.84×10−6(V−V bg). From the viewpoint of fluid dynamics, we interpret this equation as indicating that ICMEs with 0 km s−1≤V−V bg≤2300 km s−1 are controlled mainly by the hydrodynamic Stokes drag force, while the aerodynamic drag force is a predominant factor for the propagation of ICME with V−V bg\u003e2300 km s−1.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "Epub 2014 Jan 23.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://dx.doi.org/10.1007/s11207-014-0472-3"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/21224"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Springer", "subitem_publisher_language": "en"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1007/s11207-014-0472-3", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "The original publication is available at www.springerlink.com.", "subitem_rights_language": "en"}]}, "item_10_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0038-0938", "subitem_source_identifier_type": "PISSN"}]}, "item_1615787544753": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_ab4af688f83e57aa", "subitem_version_type": "AM"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Iju, T.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "55907", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tokumaru, M.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "55908", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Fujiki, K.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "55909", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-21"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Iju_slowicme_manuscript.pdf", "filesize": [{"value": "269.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 269300.0, "url": {"label": "Iju_slowicme_manuscript.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/19121/files/Iju_slowicme_manuscript.pdf"}, "version_id": "b1f43260-4318-4b50-a9d0-ddd66e814de2"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Coronal mass ejections", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Interplanetary coronal mass ejections", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Plasma physics", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Radio scintillation", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Kinematic Properties of Slow ICMEs and an Interpretation of a Modified Drag Equation for Fast and Moderate ICMEs", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Kinematic Properties of Slow ICMEs and an Interpretation of a Modified Drag Equation for Fast and Moderate ICMEs", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["881"], "permalink_uri": "http://hdl.handle.net/2237/21224", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2015-02-20"}, "publish_date": "2015-02-20", "publish_status": "0", "recid": "19121", "relation": {}, "relation_version_is_last": true, "title": ["Kinematic Properties of Slow ICMEs and an Interpretation of a Modified Drag Equation for Fast and Moderate ICMEs"], "weko_shared_id": -1}
