• Description:
  Bubbles bursting at the ocean surface are an important source of ocean-spray aerosol, with implications on radiative and cloud processes. Yet, very large uncertainties exist on the role of key physical controlling parameters, including wind speed, sea state and water temperature. We propose a mechanistic sea spray generation function that is based on the physics of bubble bursting. The number and mean droplet radius of jet and film drops is described by scaling laws derived from individual bubble bursting laboratory and numerical experiments, as a function of the bubble radius and the water physico-chemical properties (viscosity, density and surface tension, all functions of temperature), with drops radii at production from 0.1 to
