The wave normal directions with respect to the magnetic field have been discussed as functions of wave frequency normalized by the local gyrofrequency and of the slope, df/dt of an emission. Two different kinds of chorus structures (rising tone and impulsive one) have been treated. A comparison of the present behaviour of off-equatorial wave normal directions with the previous equatorial wave normal measurements has enabled us to discuss the generation and propagation mechanism of chorus emissions with different structures (rising tone, falling tone, constant frequency tone and impulsive one), and finally we suggest the future problems to study.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004064","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":"Research Institute of Atmospherics, Nagoya University/Research Institute of Atmospherics, Nagoya University/Department of Electrical and Electronic Engineering, Faculty of Engineering, Chiba University/Research Institute of Atmospherics, Nagoya University/Laboratoire de Physique et Chimie de l'Environment, CNRS/Laboratoire de Physique et Chimie de l'Environment, CNRS"}]},"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":"KJ00000035995.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035995","url":"https://nipr.repo.nii.ac.jp/record/4064/files/KJ00000035995.pdf"},"version_id":"ba07a11b-390f-4441-83bd-72eaada84d7d"}]},"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":"The wave normal directions of chorus emissions in the outer magnetosphere","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The wave normal directions of chorus emissions in the outer magnetosphere"}]},"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":"4064","relation_version_is_last":true,"title":["The wave normal directions of chorus emissions in the outer magnetosphere"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:24:18.840333+00:00"}
