Reviews recent work on how sea spray contributes to the sea surface heat and moisture budgets. In the presence of spray, the near-surface atmosphere is characterized by a droplet evaporation layer (DEL) with a height that scales with the significant-wave amplitude. The majority of spray transfer processes occur within this layer. Eulerian and Lagrangian models and a simple analytical model are used to study the processes important in spray droplet dispersion and evaporation within this DEL.
