Theoretical consideration and a numerical model revealed the following mechanism: The winter northerly wind over the Okinawa Trough blows against the Kuroshio, generating upwelling within the inshore side of the Kuroshio. This winter upwelling makes the mean Kuroshio path separate from the continental slope in the northern Okinawa Trough so that baroclinic instability destabilizes the Kuroshio path. Furthermore, a new time series of satellite-derived geostrophic velocity distribution was developed in a section across the Kuroshio in the period 1992–2010. This dataset indicated that the interannual amplitude modulation of the seasonality is mainly caused by interannual variation in the winter northerly wind over the northern Okinawa Trough.","subitem_description_type":"Other"}]},"item_8_full_name_2":{"attribute_name":"著者よみ","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ナカムラ, ヒロヒコ"}]}]},"item_8_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"NAKAMURA, Hirohiko"}]}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_8_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_8_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"20540428"}]},"item_8_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 啓彦"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"20540428seika.pdf","filesize":[{"value":"209.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20540428seika.pdf","url":"https://ir.kagoshima-u.ac.jp/record/2205/files/20540428seika.pdf"},"version_id":"ab333d37-f6d4-4069-98be-0f4b9bba86e8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"黒潮流路","subitem_subject_scheme":"Other"},{"subitem_subject":"沖縄トラフ","subitem_subject_scheme":"Other"},{"subitem_subject":"不安定現象","subitem_subject_scheme":"Other"},{"subitem_subject":"冬季季節風","subitem_subject_scheme":"Other"},{"subitem_subject":"人工衛星海面高度計","subitem_subject_scheme":"Other"},{"subitem_subject":"海洋大循環モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"黒潮小蛇行","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"東シナ海における黒潮の冬・春期の不安定化とその経年変動のメカニズムの解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東シナ海における黒潮の冬・春期の不安定化とその経年変動のメカニズムの解明"}]},"item_type_id":"8","owner":"3","path":["159"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-01-06"},"publish_date":"2015-01-06","publish_status":"0","recid":"2205","relation_version_is_last":true,"title":["東シナ海における黒潮の冬・春期の不安定化とその経年変動のメカニズムの解明"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T05:53:05.453757+00:00"}
