We call these \"dark streams\" in this work. These dark streams are observed to move and change location and their width slightly in a series of succesive scenes of NOAA images; however, distributions seem to be restricted to areas of some specific topographies. We measured air temperature and wind speed at one point by means of one of our AWS (Automated Weather Station) system. Air temperature was not particularly low and remained steady, and wind speed was constantly high, 13m/s or more. TBB analyzed from NOAA AVHRR may provide surface temperatures which are thought to be proportional to the air temperature which is equalized to emittance temperature of the blowing and drifting snow particles. On the basis of these data, air temperature inside the stream was 15℃ or higher than that outside. Along the central line of the stream, air temperature was analyzed to vary with height at the dry adiabatic lapse rate. From these observational results it may be considered that these dark stream images are composed of a warmer air stream compared with that of the outside and a strongly forced downward current along the slope.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008988","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.5","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science,Hokkaido University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Toshiba"},{"subitem_text_language":"en","subitem_text_value":"Suzaka Public Health Center"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"北海道大学低温科学研究所"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"東芝"},{"subitem_text_value":"須坂保健所環境衛生課"},{"subitem_text_value":"国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1997-03-01"}],"displaytype":"detail","filename":"KJ00000140337.pdf","filesize":[{"value":"407.6 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000140337","url":"https://nipr.repo.nii.ac.jp/record/8988/files/KJ00000140337.pdf"},"version_id":"38a6e0b6-b6ca-4d8e-9a07-58043f32f78d"}]},"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":"カタバ風帯に見られるダークストリーム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"カタバ風帯に見られるダークストリーム"},{"subitem_title":"Dark streams observed on NOAA satellite images over the Katabatic wind zone, Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1116"],"pubdate":{"attribute_name":"公開日","attribute_value":"1997-03-01"},"publish_date":"1997-03-01","publish_status":"0","recid":"8988","relation_version_is_last":true,"title":["カタバ風帯に見られるダークストリーム"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:13:06.567930+00:00"}
