The temporal evolution and the final profile of the mean flow are examined, starting with a random perturbation imposed on it under the assumption that the velocity and pressure fields are uniform in the mean flow direction.  It is found that the mean velocity profile changes due to the shear-Coriolis instability.  If there is a locally unstable regionin a stable rotating simple shear, the mean velocity profile there is deformed into a linear one with nearly-zero absolute vorticity. An analogy holds between rotating uniformly sheared turbulence and thermally convective turbulence that the region of nearly-zero absolute vorticity in the former corresponds to that of nearly-uniform temperature in the latter.\"","subitem_description_type":"Abstract"}]},"item_5_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-633X","subitem_source_identifier_type":"ISSN"}]},"item_5_text_8":{"attribute_name":"報告書番号","attribute_value_mlt":[{"subitem_text_value":"NIFS-623"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"\"Tanaka,  M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kida,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yanase,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawahara,  G.\"","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"zero absolute vorticity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shear-Coriolis instability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"analyogy with convective turbulence","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"Zero-absolute-vorticity State in a Rotating Turbulent Shear Flow","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Zero-absolute-vorticity State in a Rotating Turbulent Shear Flow","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["32"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"10298","relation_version_is_last":true,"title":["Zero-absolute-vorticity State in a Rotating Turbulent Shear Flow"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:51:30.685605+00:00"}
