The model can calculate each particle trajectory over a flat and uniform snow, under a steady wind with turbulence, modeled by a random-flight model. Hence, unlike another numerical methods, the transition process between saltation and suspension can be strictly treated in the model. In the calculation of particle eddy diffusivity, the calculated effective settling velocity and concentration for particles has been fitted with the power law given by the standard turbulent diffusion theory. The estimated eddy diffusivity for the particles shows a significant decrease from the eddy viscosity, particularly at high positions (～10m).","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"160764","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nemoto, Masaki"}]},{"nameIdentifiers":[{"nameIdentifier":"160765","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishimura, Kouichi"}]},{"nameIdentifiers":[{"nameIdentifier":"160766","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kobayashi, Shun'ichi"}]},{"nameIdentifiers":[{"nameIdentifier":"160767","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Izumi, Kaoru"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学積雪地域災害研究センター"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00183327","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03877892","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"根本, 征樹"}],"nameIdentifiers":[{"nameIdentifier":"160760","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西村, 浩一"}],"nameIdentifiers":[{"nameIdentifier":"160761","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 俊一"}],"nameIdentifiers":[{"nameIdentifier":"160762","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"和泉, 薫"}],"nameIdentifiers":[{"nameIdentifier":"160763","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-20"}],"displaytype":"detail","filename":"25_33-39.pdf","filesize":[{"value":"371.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25_33-39.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/27971/files/25_33-39.pdf"},"version_id":"6022d638-5ef5-4eff-8e93-d619a8a3b9d2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Drifting snow","subitem_subject_scheme":"Other"},{"subitem_subject":"Suspension layer","subitem_subject_scheme":"Other"},{"subitem_subject":"Random-flight model","subitem_subject_scheme":"Other"},{"subitem_subject":"Turbulent diffusion theory","subitem_subject_scheme":"Other"},{"subitem_subject":"Particle eddy diffusivity","subitem_subject_scheme":"Other"},{"subitem_subject":"吹雪","subitem_subject_scheme":"Other"},{"subitem_subject":"浮遊層","subitem_subject_scheme":"Other"},{"subitem_subject":"ランダムフライトモデル","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流拡散理論","subitem_subject_scheme":"Other"},{"subitem_subject":"粒子拡散係数","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":"吹雪浮遊層における雪粒子の乱流拡散係数  (小林俊一教授退官記念号）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"吹雪浮遊層における雪粒子の乱流拡散係数  (小林俊一教授退官記念号）"},{"subitem_title":"吹雪浮遊層における雪粒子の乱流拡散係数  (小林俊一教授退官記念号）","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1558"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-08"},"publish_date":"2016-03-08","publish_status":"0","recid":"27971","relation_version_is_last":true,"title":["吹雪浮遊層における雪粒子の乱流拡散係数  (小林俊一教授退官記念号）"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:57:52.282558+00:00"}
