A comparison of Langmuir turbulence parameterizations and key wave effects in a numerical model of the North Atlantic and Arctic Oceans
Ali, Alfatih; Christensen, Kai Håkon; Breivik, Øyvind; Bertino, Laurent; Malila, Mika Petteri; Raj, Roshin Pappukutty; Chassignet, Eric P.; Bakhoday Paskyabi, Mostafa (Peer reviewed; Journal article, 2019)Five different parameterizations of Langmuir turbulence (LT) effect are investigated in a realistic model of the North Atlantic and Arctic using realistic wave forcing from a global wave hindcast. The parameterizations ... -
A general framework to obtain seamless seasonal–directional extreme individual wave heights—Showcase Ekofisk
Bohlinger, Patrik; Economou, Theodoros; Aarnes, Ole Johan; Malila, Mika Petteri; Breivik, Øyvind (Journal article; Peer reviewed, 2023)Extreme wave climate provides the basis for safe design of offshore structures and is crucial for planning and executing offshore operations. Covariate modeling of extremes significantly enriches and improves estimates of ... -
An investigation into the dynamical and statistical properties of dominant ocean surface waves using close-range remote sensing
Malila, Mika Petteri (Doctoral thesis, 2022-09-16)Denne avhandlingen er basert på forskningsresultat som behandler statistiske og dynamiske egenskaper av dominante vinddrevne overflatebølger i åpent hav. Med uttrykket dominante bølger refererer vi her til de største ... -
Langmuir Turbulence in the HYCOM Ocean Model
Malila, Mika Petteri (Master thesis, 2017)The impact of parameterising the turbulent mixing induced by surface wave-driven Langmuir turbulence is investigated for a basin-scale configuration of the hybrid-coordinate ocean circulation model HYCOM. Two-year, non-data ... -
On the Groupiness and Intermittency of Oceanic Whitecaps
Malila, Mika Petteri; Thomson, J.; Breivik, Øyvind; Benetazzo, A.; Scanlon, B.; Ward, B. (Journal article; Peer reviewed, 2022)The enhancement of wave breaking activity during wave group passage is investigated using coherent field observations of the instantaneous sea surface elevation and whitecap coverage from platform-based stereo video ... -
Statistical and Dynamical Characteristics of Extreme Wave Crests Assessed with Field Measurements from the North Sea
Malila, Mika Petteri; Barbariol, Francesco; Benetazzo, Alvise; Breivik, Øyvind; Magnusson, Anne Karin; Thomson, Jim; Ward, Brian (Journal article; Peer reviewed, 2023)Wave crests of unexpected height and steepness pose a danger to activities at sea, and long-term field measurements provide important clues for understanding the environmental conditions that are conducive to their generation ...
