Here we also focus on such a case by targeting the inhabited land area, Alaska. During 2–18 August 2015, ship-borne radiosonde sounding observations were performed every 12 h (except 6-hourly from 12:00 UTC 11 August to 00:00 UTC 14 August) around the Chukchi Sea. To assess the impact of those extra radiosonde observations, two sets of ensemble forecast experiments (CTLf and OSE_Af) were produced, which were respectively initialized by atmospheric reanalysis data without (CTL) and with (OSE_A) additional assimilation of those data. The tropospheric circulation fields are compared to verify their differences in forecast performance. While two forecasts have similar performance in the earlier spin-up period of the analysis-forecast cycle (from 4 to 7 August), their performance tends to diverge in the later period (from 11 to 18 August) due to the accumulated influence on the error reduction in OSE_Af. Among the improved forecasts in OSE_Af, two most outperformed forecasts, each initialized on 00:00 UTC 12 and 00:00 UTC 14, show a notable improvement in predicting the developing trough over Alaska on 16–17 August by suppressing the development of erroneous high anomalies in CTLf. Though the positive impact of single-point observations is limited in a space, our results suggest that enhanced radiosonde profile observations in the data-sparse polar ocean could be beneficial for the forecasts beyond the observational area.","subitem_description_type":"Abstract"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2018.12.005"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2018.12.005","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"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":"Lee, Min-Hee","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kim, Joo-Hong","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Song, Hyo-Jong","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue, Jun","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sato, Kazutoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamazaki, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Arctic ocean","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Weather forecasts","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ship-borne radiosonde observation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Data assimilation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Observing system experiment","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Potential benefit of extra radiosonde observations around the Chukchi Sea for the Alaskan short-range weather forecast","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Potential benefit of extra radiosonde observations around the Chukchi Sea for the Alaskan short-range weather forecast"},{"subitem_title":"Potential benefit of extra radiosonde observations around the Chukchi Sea for the Alaskan short-range weather forecast","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"25","path":["1984"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-09-30"},"publish_date":"2019-09-30","publish_status":"0","recid":"15924","relation_version_is_last":true,"title":["Potential benefit of extra radiosonde observations around the Chukchi Sea for the Alaskan short-range weather forecast"],"weko_creator_id":"25","weko_shared_id":-1},"updated":"2023-07-25T13:20:06.395292+00:00"}
