Volume-preserving Lagrangian averaging using polar factorization
Abhijeet Minz, Lois E. Baker, Jacques Vanneste
The generalised Lagrangian mean (GLM) theory of Andrews & McIntyre provides a powerful framework to study the interactions between waves and flows. A drawback of this theory is tha…

Efficient Lagrangian averaging with exponential filters
Abhijeet Minz, Lois E. Baker, Hossein A. Kafiabad +1
Lagrangian averaging is a valuable tool for the analysis and modelling of multiscale processes in fluid dynamics. The numerical computation of Lagrangian (time) averages from simul…

Lagrangian filtering for wave-mean flow decomposition
Lois E. Baker, Hossein A. Kafiabad, Cai Maitland-Davies +1
Geophysical flows are typically composed of wave and mean motions with a wide range of overlapping temporal scales, making separation between the two types of motion in wave-resolv…
