On average, more than 90% of ensemble members predicted the existence of the EACs for lead times of ≤3.0 days. The average central position error for the EACs decreases to ≤433.1 km (half the mean radius of the mature 26 EACs) for a lead time of 3.0 days, with the average central pressure error of ∼6.9 hPa. The GEFS reforecast for the 26 EACs shows a similar forecast skill to the GEFS reforecast and operational medium-range ensemble forecasts for 10 EACs occurred in summer during 2008–2016. There is no trend of improvements in forecast skills of existence, central pressure and position of the EACs at all lead times. In the verification of the strike probability for EACs within a 400-km radius, the probability information is useful in 1.0- to 5.0-day forecasts, although the forecast probabilities were overconfident for lead times more than 1.0 days.","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.2019.02.003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2019.02.003","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":"Yamagami, Akio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsueda, Mio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Hiroshi L.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Arctic cyclone","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Medium-range ensemble forecast","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Forecast skill","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Predictability","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":"Skill of medium-range reforecast for summertime extraordinary Arctic Cyclones in 1986–2016","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Skill of medium-range reforecast for summertime extraordinary Arctic Cyclones in 1986–2016"},{"subitem_title":"Skill of medium-range reforecast for summertime extraordinary Arctic Cyclones in 1986–2016","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"25","path":["1983"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-06-30"},"publish_date":"2019-06-30","publish_status":"0","recid":"15624","relation_version_is_last":true,"title":["Skill of medium-range reforecast for summertime extraordinary Arctic Cyclones in 1986–2016"],"weko_creator_id":"25","weko_shared_id":-1},"updated":"2023-07-25T13:26:21.551886+00:00"}
