The study of the relationship between wind speed, altitude, and the geometric properties of the ocean surface (characteristics of dominant waves, surface roughness, see the wave-breaking rate) is a central topic both (1) for the representation of the

Stably stratified fluid flow over smooth hills is an important process in environmental fluid mechanics. The aim of this article is to point out some of the key features of this phenomenon from both the physical and the mathematical modeling point of

Turbulent fluxes at the air‐sea interface are estimated with data collected in 2011 to 2017 with a low‐profile platform during six experiments in four regions. The observations were carried out with moderate winds (2‐10 m s‐1) and averaged wa
