Data assimilation using adaptive, non-conservative, moving mesh models
Aydogdu, Ali; Carrassi, Alberto; Guider, Colin T.; Jones, Chris K.R.T.; Rampal, Pierre (Peer reviewed; Journal article, 2019)Numerical models solved on adaptive moving meshes have become increasingly prevalent in recent years. Motivating problems include the study of fluids in a Lagrangian frame and the presence of highly localized structures ... -
Driving Mechanisms of an Extreme Winter Sea Ice Breakup Event in the Beaufort Sea
Davy, Richard; Olason, Einar; Rampal, Pierre; Spensberger, Clemens; Williams, Timothy; Korosov, Anton; Spengler, Thomas; Rheinlænder, Jonathan W. (Journal article; Peer reviewed, 2022)The thick multiyear sea ice that once covered large parts of the Arctic is increasingly being replaced by thinner and weaker first-year ice, making it more vulnerable to breakup by winds. We use the neXtSIM sea ice model ... -
Uncertainties in Arctic sea ice thickness and volume: new estimates and implications for trends
Zygmuntowska, Marta; Rampal, Pierre; Ivanova, Natalia; Smedsrud, Lars Henrik (Peer reviewed; Journal article, 2014-04-22)Sea ice volume has decreased in the last decades, evoked by changes in sea ice area and thickness. Estimates of sea ice area and thickness rely on a number of geophysical parameters which introduce large uncertainties. To ...
