The U2H map explains the effect of (sub)mesoscale currents on significant wave height statistics
Han Wang, Ana B. Villas Bôas, Jacques Vanneste +1
Currents modulate the energy of surface gravity waves, leading to spatial inhomogeneities in significant wave height (SWH). Previous work indicates that the overall scale of the in…
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…
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…
Inhomogeneity-induced wavenumber diffusion
Michael R. Cox, Hossein A. Kafiabad, Jacques Vanneste
Inertia-gravity waves are scattered by background flows as a result of Doppler shift by a non-uniform velocity. In the WKB regime, the scattering process reduces to a diffusion in…
