Regression analysis gives the drift threshold friction velocity (u<jats:sub>*t</jats:sub>), assuming an exponential drift profile and a simple drift to friction velocity relationship. Measurements over 15 snow covers show that u<jats:sub>*t</jats:sub> is influenced more by snow density and particle size than by ambient temperature and humidity, and varies from 0.27 to 0.69 ms<jats:sup>–1</jats:sup>. Schmidt’s threshold algorithm and a modified version used in SNOWPACK (a snow-cover model) agree well with observations if small bond sizes are assumed. Using particle hydraulic diameters, obtained from image processing, Bagnold’s threshold parameter is 0.18. Roughness lengths (z<jats:sub>0</jats:sub>) vary between snow covers but are constant until the start of drift. Threshold roughness lengths are proportional to <jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"gif\" xlink:type=\"simple\" xlink:href=\"S0022143000209337_inline23\"/>. The influence of macroscopic objects on the roughness length is shown by the lower values measured over the smooth and flat snow surface of the wind tunnel (0.04 ≤ z<jats:sub>0</jats:sub> ≤ 0.13 mm), compared to field measurements. Mean drifting-snow grain sizes for mainly new and partly decomposed snow are 100–175 μm, and independent of surface particle size.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388845124202241","@type":"Researcher","foaf:name":[{"@value":"Andrew Clifton"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845124202242","@type":"Researcher","foaf:name":[{"@value":"Jean-Daniel Rüedi"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845124202240","@type":"Researcher","foaf:name":[{"@value":"Michael Lehning"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00221430"},{"@type":"EISSN","@value":"17275652"}],"prism:publicationName":[{"@value":"Journal of Glaciology"}],"dc:publisher":[{"@value":"International Glaciological Society"}],"prism:publicationDate":"2006","prism:volume":"52","prism:number":"179","prism:startingPage":"585","prism:endingPage":"596"},"reviewed":"false","dc:rights":["https://www.cambridge.org/core/terms"],"url":[{"@id":"https://www.cambridge.org/core/services/aop-cambridge-core/content/view/S0022143000209337"}],"createdAt":"2007-11-22","modifiedAt":"2019-05-03","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050307280801840640","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Estimating the effect of snowdrift formation on turbulent airflow and subsequent snowdrift around three types of fences"}]},{"@id":"https://cir.nii.ac.jp/crid/1360013168828897536","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Hysteresis and Surface Shear Stresses During Snow-Particle Aeolian Transportation"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707321379200","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Development of a large-eddy simulation coupled with Lagrangian snow transport model"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679617953408","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Blowing Snow Experiments in a Cold Wind Tunnel"},{"@language":"ja","@value":"低温風洞装置を用いた吹雪の実験的研究"},{"@language":"ja-Kana","@value":"テイオン フウドウ ソウチ オ モチイタ フブキ ノ ジッケンテキ ケンキュウ"}]},{"@id":"https://cir.nii.ac.jp/crid/2051433317037089664","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Development of a snowdrift model with the lattice Boltzmann method"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.3189/172756506781828430"},{"@type":"CROSSREF","@value":"10.1007/s10546-022-00688-8_references_DOI_A6sPQ4fRak8yzs7tXS085FxuRaq"},{"@type":"CROSSREF","@value":"10.1186/s40645-021-00449-0_references_DOI_A6sPQ4fRak8yzs7tXS085FxuRaq"},{"@type":"CROSSREF","@value":"10.1016/j.jweia.2018.09.027_references_DOI_A6sPQ4fRak8yzs7tXS085FxuRaq"},{"@type":"CROSSREF","@value":"10.5359/jawe.37.34_references_DOI_A6sPQ4fRak8yzs7tXS085FxuRaq"},{"@type":"CROSSREF","@value":"10.1016/j.jweia.2025.106089_references_DOI_A6sPQ4fRak8yzs7tXS085FxuRaq"}]}
