In this study, we utilized a snow particle counter (SPC) developed to observe snow particle size distributions and snow mass flux. Using high-frequency signals from the SPC transducer, we obtained the sizes of individual particles and their durations in the sampling area. Measurements were first conducted in the field, with more precise measurements being obtained in a boundary layer established in a cold wind tunnel. The obtained results were compared with the results of a numerical analysis. Data on snow particle speeds, vertical velocity profiles, and their dependence on wind speed obtained in the field and in the wind tunnel experiments were in good agreement: both snow particle speed and wind speed increased with height, and the former was always 1 to 2m s(-1) less than the latter below a height of 1 m. Thus, we succeeded in obtaining snow particle speeds in drifting snow, as well as revealing the dependence of particle speed on both grain size and wind speed. The results were verified by similar trends observed using random flight simulations. However, the difference between the particle speed and the wind speed in the simulations was much greater than that observed under real conditions. Snow transport by wind is an aeolian process. Thus, the findings presented here should be also applicable to other geophysical processes relating to the aeolian transport of particles, such as blown sand and soil.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "AMER GEOPHYSICAL UNION", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1002/2014JD021686"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2169-8996", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kouichi Nishimura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Chika Yokoyama", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yoichi Ito", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masaki Nemoto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Florence Naaim-Bouvet", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Herve Bellot", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Koji Fujita", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Snow particle speeds in drifting snow", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Snow particle speeds in drifting snow", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/6164", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-05-24"}, "publish_date": "2023-05-24", "publish_status": "0", "recid": "6164", "relation": {}, "relation_version_is_last": true, "title": ["Snow particle speeds in drifting snow"], "weko_shared_id": -1}
