Abstract
A model with a discrete droplet size distribution has been built in order to investigate the fate and influence of marine spray droplets dispersed by atmospheric turbulence as they evaporate. In its present state the model considers freshwater droplets between 5 and 105 μm in radius that are ejected from a water surface by bursting air bubbles. The droplets are then diffused in a fully developed atmospheric surface layer. The droplet population is separated into 10 categories according to their size. The mass concentration of each category is treated as a scalar field, like sensible heat and water vapor concentration. The model is adjusted for comparison with measurements of turbulence statistics and droplet distributions taken in the air-water tunnel. The influence of evaporating droplets on the humidity and sensible heat fields and fluxes, as well as the coupling of turbulent diffusion and evaporation is demonstrated. -from Authors
