We performed a spatiotemporal analysis of climatic conditions during phases of maximum warming (i.e., 1935-1945, 1988-1995, and 2005-2009) in northeastern Eurasia and compared the magnitude of warming and its effect on permafrost among these critical periods. Our observations of permafrost landscape dynamics confirmed that the last two warming phases have played major roles in changing the environment.Data analysis has revealed regional patterns in the intensity of warming. Areas south of 60-62° latitude experienced no rise in air temperature during the Arctic warming period (1935-1945), whereas during 1988-1995, the center of warming shifted to the south of northeastern Eurasia. The last phase of warming (2005-2009) was characterized by maximum values of mean annual air temperature and the thawing index, and a decrease in the freezing index throughout northeastern Eurasia.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":" 過去20年間、気候変化は北東ユーラシアの低温プロセスを活発化させて、凍土域の景観及び社会・経済システムにも影響を与えた。本研究は北極温暖化により進行した近年の温暖化の局面を評価することを目的とする。そのため、北東ユーラシアの三つの温暖時期(1935-1945, 1988-1995, 2005-2009)における気候の時空間解析を行い、温暖化の程度と凍土に対するその影響を比較した。最近20年間の温暖化が凍土域の環境変化に多大に影響したことが観測から明らかになった。 データ解析から温暖化の強度において地域的パターンがあることが分かった。北緯60-62度の以南において、1935-1945年の期間に気温上昇は見られなかったが、1988-1995年の期間に温暖化の中心が北東ユーラシアの南部までシフトした。2005-2009年の温暖期においては、年平均気温と積算暖度の最大値を示して、積算寒度は反対に減少する特徴が見られた。 ","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID(NAID)","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110009794520","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2014.02.001"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2014.02.001","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"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":"Fedorov, A.N."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ivanova, R.N."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Park, H."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hiyama, T."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iijima, Y."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fedorov, A.N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ivanova, R.N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Park, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hiyama, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iijima, Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Climate change","subitem_subject_scheme":"Other"},{"subitem_subject":"Freezing index","subitem_subject_scheme":"Other"},{"subitem_subject":"Thawing index","subitem_subject_scheme":"Other"},{"subitem_subject":"Permafrost landscape","subitem_subject_scheme":"Other"},{"subitem_subject":"Climate change","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Freezing index","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Thawing index","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Permafrost landscape","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":"Recent air temperature changes in the permafrost landscapes of northeastern Eurasia","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Recent air temperature changes in the permafrost landscapes of northeastern Eurasia"},{"subitem_title":"Recent air temperature changes in the permafrost landscapes of northeastern Eurasia","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"27","path":["1335"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-14"},"publish_date":"2014-10-14","publish_status":"0","recid":"10043","relation_version_is_last":true,"title":["Recent air temperature changes in the permafrost landscapes of northeastern Eurasia"],"weko_creator_id":"27","weko_shared_id":27},"updated":"2023-07-25T16:22:08.126045+00:00"}
