In the frame rotating with the precessional angular velocity, the basic flow is a steady\r velocity field linear in coordinates in an unbounded domain. For the case of slow precession, without\r strain, the growth rate takes the same value as that of Kerswell (1993) though the basic flow is different.\r We find that, in the absence of strain, the growth rate approaches the angular velocity of the basic flow as\r the precessional angular velocity is increased. The cooperative action of the weak Coriolis force and the\r elliptical straining field is investigated both numerically and analytically. An analysis of using the\r Mathieu method reveals that the elliptical instability is weakened by the precession, while the\r precessional instability is either enhanced or weakened depending on the orientation of the strain."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"local stability"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-05-05"}],"displaytype":"preview","filename":"Local instability of an Elliptical Flow Subjected to a Coriolis Force.pdf","filesize":[{"value":"327 Kb"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://meral.edu.mm/record/735/files/Local instability of an Elliptical Flow Subjected to a Coriolis Force.pdf"},"version_id":"8d19765e-da2c-433a-99b7-a34fe797f40b"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"12","subitem_journal_title":"Journal of the Physical Society of Japan","subitem_volume":"78"}]},"item_1583103147082":{"attribute_name":"Conference papaers","attribute_value_mlt":[{}]},"item_1583103211336":{"attribute_name":"Books/reports/chapters","attribute_value_mlt":[{}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_supervisor(s)":[]}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Me Me Naing"},{"subitem_authors_fullname":"Fukumoto, Yasuhide"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2009"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"https://umoar.mu.edu.mm/handle/123456789/277"},"item_title":"Local Instability of an Elliptical Flow Subjected to a Coriolis Force","item_type_id":"21","owner":"1","path":["1582967046255"],"publish_date":"2020-03-05","publish_status":"0","recid":"735","relation_version_is_last":true,"title":["Local Instability of an Elliptical Flow Subjected to a Coriolis Force"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2021-12-13T01:38:33.021969+00:00"}
