This paper aims at clarifying the spatial and temporal structure of urban heat island phenomena in Tokyo. As there have been only several meteorological stations in Tokyo，it has been difficult to gain detailed isothermal charts which show both temporal and spatial patterns of urban heat island phenomena in Tokyo. Annual mean daily minimum temperature patterns show typical urban heat island phenomena in Tokyo，where the center of high temperatures can be seen in downtown Tokyo. However，in case of daily maximum temperature patterns，the center of heat island moves to northern inland area，whereas low temperature appears in downtown and bayside areas. An attempt was made to clarify long term variations in daily maximum and minimum temperatures，and diurnal temperature ranges in Tokyo for the last 120 years. The results show that daily minimum temperatures have increased rapidly since 1950s，and that diurnal temperature ranges have decreased remarkably since 1940s.","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"postprint","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京都立大学都市研究センター"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00134354","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03863506","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三上, 岳彦"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-03-17"}],"displaytype":"detail","filename":"20024-060-008.pdf","filesize":[{"value":"438.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20024-060-008.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/5572/files/20024-060-008.pdf"},"version_id":"d603e59c-ffc3-4453-a3be-1d2afbc46591"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Heat Island","subitem_subject_scheme":"Other"},{"subitem_subject":"Diurnal Temperature Range","subitem_subject_scheme":"Other"},{"subitem_subject":"Sea breeze","subitem_subject_scheme":"Other"},{"subitem_subject":"Cloud Amount","subitem_subject_scheme":"Other"},{"subitem_subject":"ヒートアイランド","subitem_subject_scheme":"Other"},{"subitem_subject":"気温日較差","subitem_subject_scheme":"Other"},{"subitem_subject":"海風","subitem_subject_scheme":"Other"},{"subitem_subject":"雲量","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"東京におけるヒートアイランドの時空間構造とその長期変動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東京におけるヒートアイランドの時空間構造とその長期変動"}]},"item_type_id":"3","owner":"3","path":["1320"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-31"},"publish_date":"2017-03-31","publish_status":"0","recid":"5572","relation_version_is_last":true,"title":["東京におけるヒートアイランドの時空間構造とその長期変動"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T17:13:50.941247+00:00"}
