Along with the recent sea ice decrease, the Eurasia continent and North America have experienced abnormally cold winters in recent years (2005/06, 2011/12, 2012/13 for Eurasia and 2009/10, 2010/11, 2013/14 for North America), which is likely to attribute to the atmospheric responses to the reduced sea ice zones [Mori et al. 2014]. To assess the causes of sea ice variability in early winter (November-December), where surface heat fluxes is prominent, we have examined the role of ocean heat advection on seasonal forecasting of sea ice area based on atmosphere and ocean datasets during several decades. The statistical analysis suggests that the interannual variability of sea ice area in these regions can be skillfully predicted by using ocean temperature data at the stage of 3 months to 1 year ahead. In this seminar, we will review these studies and discuss the remaining issues.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"Polar Meteorology and Glaciology Group seminar / 気水圏コロキウム \n日時：7月20日（水）10:00-10:50 \n場所：C301（3階セミナー室）","subitem_description_type":"Other"}]},"item_10005_text_18":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"国立極地研究所"}]},"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":"中野渡, 拓也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakanowatari, Takuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"海氷面積"},{"subitem_subject":"季節海氷域"},{"subitem_subject":"予測可能性"},{"subitem_subject":"sea ice extent","subitem_subject_language":"en"},{"subitem_subject":"seasonal variations","subitem_subject_language":"en"},{"subitem_subject":"predictability","subitem_subject_language":"en"}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"北半球の季節海氷域の初冬海氷面積の予測可能性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北半球の季節海氷域の初冬海氷面積の予測可能性"},{"subitem_title":"Predictability of early winter sea ice extent in the Northern Hemisphere","subitem_title_language":"en"}]},"item_type_id":"10005","owner":"17","path":["1682"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-07-19"},"publish_date":"2016-07-19","publish_status":"0","recid":"12730","relation_version_is_last":true,"title":["北半球の季節海氷域の初冬海氷面積の予測可能性"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:04:00.597119+00:00"}
