The five-day trajectories of the air parcels were estimated and analyzed. In the middle troposphere in winter, air parcels were usually from the lower troposphere over the Atlantic. However, in January, most of the air parcels came from latitudes higher than 60°S . The trajectories had little vertical motion and were associated with a low pressure system that forms along the coastal region of Antarctica only in summer. In the lower troposphere, trajectories could be classified as originating in one of three regions: the Southern Ocean, the continental interior, and the east coast. In contrast to the middle troposphere, air parcels from the Southern Ocean had the lowest frequency, irrespective of the time of year. This is partially due to a low pressure system that blocks air parcels from outside the continent. Most trajectories are affected by the drainage flow. An amplified quasi-stationary planetary wave for September to November and a blocking circulation in June make trajectories pass over Antarctica.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002975","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":"AA1129795X","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":"Department of Polar Science, The Graduate University for Advanced Studies/National Institute of Polar Research/National Institute of Polar Research/Hydrospheric Atmospheric Research Center, Nagoya University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2004-11-01"}],"displaytype":"detail","filename":"KJ00001036822.pdf","filesize":[{"value":"5.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00001036822","url":"https://nipr.repo.nii.ac.jp/record/2975/files/KJ00001036822.pdf"},"version_id":"c209ade6-0818-41b3-b4c3-afda8b073b88"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"trajectory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Syowa Station","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"polar vortex","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary wave","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Seasonal variation of air transport in the Antarctic and Atmospheric Circulation in 1997","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Seasonal variation of air transport in the Antarctic and Atmospheric Circulation in 1997"}]},"item_type_id":"1","owner":"4","path":["432"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-11-01"},"publish_date":"2004-11-01","publish_status":"0","recid":"2975","relation_version_is_last":true,"title":["Seasonal variation of air transport in the Antarctic and Atmospheric Circulation in 1997"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:39:43.595238+00:00"}
