Sea-Spray-Generation Dependence on Wind and Wave Combinations: A Laboratory Study

Abstract

This paper investigates the effect of interacting winds and waves on the surface sea spray generation flux. To this end, the Marine Aerosol Tunnel Experiment (MATE2019) was conducted at the OSU-Pytheas large wind-wave tunnel facility at Luminy, Marseille (France), in June-July 2019.A unique range of air-sea boundary conditions was generated by configuring the laboratory with four types of wave forcing and five wind speeds ranging from 8 to 20 m s -1 . The configurations included both young and developed

Sea Spray Impacts on Tropical Cyclone Olwyn Using a Coupled Atmosphere‐Ocean‐Wave Model

“…As the model of X21 is based on the wave steepness, considered the critical parameter in the generation of sea spray (e.g. Bruch et al., 2021), the model of X21 is preferred over that of Z06. This study considers, however, only one TC case which reached up to category 3.…”

“…This is because wave age provides information on the relative velocity of the dominant energetic wave with respect to the wind only, but not about the severity of the sea state, including wave breaking. The severity of the sea state is considered to be a major determinant of sea spray generation (e.g., Bruch et al., 2021).…”

Growth of surface wind-waves in water of finite depth: A laboratory experiment

“…This method, called the "profile method", is routinely used for wind parameter determination in this facility (see for example recent papers of [Villefer et al, 2021;Bruch et al, 2021] where vertical wind profiles are displayed with u * , z 0 , and U 10 determinations). Two examples of vertical wind profiles are plotted in Figure ( 5).…”

Speed and Acceleration of Droplets Generated by Breaking Wind‐Forced Waves

“…(2020) recently reported that air flow separation downstream of the wave crests increases with wind speed and wave slope. These airflow modifications are thought to have a significant impact on the droplet production in breaking waves and have previously been linked to surface features such as the significant wave height (Ovadnevaite et al., 2014), wave age (Laussac et al., 2018), and mean square slope (Bruch et al., 2021).…”

“…(2018); Bruch et al. (2021)) knowledge and data on droplet velocity and acceleration statistics remain elusive in part due to the difficulty in performing such measurements.…”
