Spray Production and Surface Foam Longevity under Breaking Waves
Abstract
We conducted field-scale observations of wave breaking and drop productions measured very near the surface (< 1 m) to develop a better understanding of drop generation in breaking waves. Our results indicate that the drop distribution for drops from 100 m to 1 cm are represented well by a two-part power law distribution with a log-log slope of -2 for drops from100 m to 1 mm and a slope of -3.5 from 1 mm to 1 cm. We developed a drop ballistics model to described the observations with an initial drop velocity from wave velocity scaling and using previously measured drop terminal velocities. Future work will need to better define drop initial velocities and drop fragmentation.
