Research | Sea Spray Fluxes Over the Ocean
 
 
We use a combination of numerical modeling and laboratory experiments to determine the sea-spray concentration in the air and the rate at which the drops evaporate and transfer energy to the airflow.
 
The contributions of sea spray drops to the total air-sea exchanges of momentum, heat, and mass remain an open question. A number of factors obscure any simple quantification of their contribution. The per-drop contribution to the fluxes is a particularly important factor, as is the number of formed drops. To estimate the per-droplet fluxes, we converge upon the low order statistics from a large number of drop trajectories, which are simulated with a recent Lagrangian Stochastic model adapted for heavy drops within the marine boundary layer. The results from simulations of sea spray drops over the ocean,suggest that common simplifications in previous sea spray models, such as the residence time in the marine boundary layer, may not be appropriate.

Below is an estimate of the re-entry temperatuer of 1000s of sea spray particules after they ahve been ejected from the surface, have flown through the lower atmospheric boundary layer over the ocean's wavy surface, and re-enter the ocean.
