We report statistical results of 150-km FAI drift velocities on a plane perpendicular to the geomagnetic field, acquired by analyzing the Doppler velocities of 150-km FAIs observed with the Equatorial Atmosphere Radar (EAR) at Kototabang, Indonesia during the period from Aug. 2007 to Oct. 2009. We found that the southward/upward perpendicular drift velocity of the 150-km FAIs tends to decrease in the afternoon and that this feature is consistent with that of F-region plasma drift velocities over the magnetic equator. The zonal component of the 150-km FAI drift velocity is westward and decreases with time, whereas the F-region plasma drift velocity observed with the incoherent scatter radar at Jicamarca, Peru, which is westward, reaches a maximum at about noon. The southward/upward and zonal drift velocities of the 150-km FAIs are smaller than that of the F-region plasma drift velocity by approximately 3 m/s and 25 m/s, respectively, on average. The large difference between the 150-km FAI and F-region plasma drift velocities may not arise from a difference in the magnetic latitudes at which their electric fields are generated. Electric fields generated at the altitude at which the 150-km FAIs occur may not be negligible.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009711","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":"Solar-Terrestrial Environment Laboratory, Nagoya University, Furo-cho, Chikusa-ku, Nagoya 464-8601"},{"subitem_text_language":"en","subitem_text_value":"Solar-Terrestrial Environment Laboratory, Nagoya University, Furo-cho, Chikusa-ku, Nagoya 464-8601"},{"subitem_text_language":"en","subitem_text_value":"Solar-Terrestrial Environment Laboratory, Nagoya University, Furo-cho, Chikusa-ku, Nagoya 464-8601"},{"subitem_text_language":"en","subitem_text_value":"National Atmospheric Research Laboratory, Gadank, Chittoor Dist., Andhra Pradesh 517112, India"},{"subitem_text_language":"en","subitem_text_value":"Research Institute for Sustainable Humanosphere, Kyoto University, Gokasho, Uji, Kyoto 611-0011"},{"subitem_text_language":"en","subitem_text_value":"Research Institute for Sustainable Humanosphere, Kyoto University, Gokasho, Uji, Kyoto 611-0011"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"名古屋大学太陽地球環境研究所"},{"subitem_text_value":"名古屋大学太陽地球環境研究所"},{"subitem_text_value":"名古屋大学太陽地球環境研究所"},{"subitem_text_value":"京都大学生存圏研究所"},{"subitem_text_value":"京都大学生存圏研究所"}]},"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":"KJ00008959679.pdf","filesize":[{"value":"426.9 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00008959679","url":"https://nipr.repo.nii.ac.jp/record/9711/files/KJ00008959679.pdf"},"version_id":"5bce22c0-639c-475a-af7f-fbbf599e9c70"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"赤道大気レーダーを用いた高度150 km沿磁力線不規則構造のドリフト速度に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"赤道大気レーダーを用いた高度150 km沿磁力線不規則構造のドリフト速度に関する研究"},{"subitem_title":"Drift velocities of 150-km Field-Aligned Irregularities observed by the Equatorial Atmosphere Radar","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":"9711","relation_version_is_last":true,"title":["赤道大気レーダーを用いた高度150 km沿磁力線不規則構造のドリフト速度に関する研究"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:14:16.804868+00:00"}
