However, there are only a limited number of studies of gravity waves in the polar region mostly because of difficulty of their observation. One of the significant issues on gravity waves is their source, because wave parameters such as wavelengths and phase velocities which are essential to evaluate the gravity wave effects on the large-scale field are highly dependent on the source. This paper describes dominant sources of gravity waves in the polar regions, namely topography, the polar- night jet, and tropical convection, by reviewing results from recent studies.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006318","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":"AA11397422","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":"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":"2000-08-01"}],"displaytype":"detail","filename":"KJ00000048058.pdf","filesize":[{"value":"694.2 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000048058","url":"https://nipr.repo.nii.ac.jp/record/6318/files/KJ00000048058.pdf"},"version_id":"3b539a34-0458-4df6-a43d-6363bed64313"}]},"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":"Sources of gravity waves in the polar middle atmosphere","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sources of gravity waves in the polar middle atmosphere"}]},"item_type_id":"1","owner":"4","path":["804"],"pubdate":{"attribute_name":"公開日","attribute_value":"2000-08-01"},"publish_date":"2000-08-01","publish_status":"0","recid":"6318","relation_version_is_last":true,"title":["Sources of gravity waves in the polar middle atmosphere"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:03:05.182691+00:00"}
