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\u2212V bg\u003e500 km\u2009s\u22121), 25 moderate (0 km\u2009s\u22121\u2264V SOHO\u2212V bg\u2264500 km\u2009s\u22121), and 6 slow (V SOHO\u2212V bg\u003c0 km\u2009s\u22121) 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\u00b10.03 AU. ii) The acceleration ends when they reach 479\u00b1126 km\u2009s\u22121; this is close to the typical speed of the solar wind during the period of this study. iii) When \u03b3 1 and \u03b3 2 are assumed to be constants, a quadratic equation for the acceleration a=\u2212\u03b3 2(V\u2212V bg)|V\u2212V bg| is more appropriate than a linear one a=\u2212\u03b3 1(V\u2212V bg), where V is the propagation speed of ICMEs, while the latter gives a smaller \u03c7 2 value than the former. For the motion of the fast and moderate ICMEs, we found a modified drag equation a=\u22122.07\u00d710\u221212(V\u2212V bg)|V\u2212V bg|\u22124.84\u00d710\u22126(V\u2212V bg). From the viewpoint of fluid dynamics, we interpret this equation as indicating that ICMEs with 0 km\u2009s\u22121\u2264V\u2212V bg\u22642300 km\u2009s\u22121 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\u2212V bg\u003e2300 km\u2009s\u22121.", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "Epub 2014 Jan 23.", "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": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Springer"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "The original publication is available at www.springerlink.com."}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "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": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Iju, T."}], "nameIdentifiers": [{"nameIdentifier": "55907", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tokumaru, M."}], "nameIdentifiers": [{"nameIdentifier": "55908", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Fujiki, K."}], "nameIdentifiers": [{"nameIdentifier": "55909", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "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_free", "mimetype": "application/pdf", "size": 269300.0, "url": {"label": "Iju_slowicme_manuscript.pdf", "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "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": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Kinematic Properties of Slow ICMEs and an Interpretation of a Modified Drag Equation for Fast and Moderate ICMEs"}]}, "item_type_id": "10", "owner": "1", "path": ["879/880/881"], "permalink_uri": "http://hdl.handle.net/2237/21224", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "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": null}
