A model for the dry deposition of particles to natural water surfaces

More realistic estimates of the deposition velocity, for aerosol particle deposition on natural water surfaces, are obtained by modifying earlier resistance models to include the effects of wave breaking and spray formation in high winds and particle growth in the humid regions near the air/water interface. Both processes act to enhance deposition by shunting the high transfer resistance to a smooth water surface. The result is to drastically reduce the dependence of deposition velocity on particle size; however, the deposition velocity is still substantially below the limiting value set by atmospheric turbulence.
