Abstract
The bursting of air bubbles produced by whitecaps is the primary mechanism in the contribution of sea spray droplets over the ocean. These evaporating droplets contribute to the transfer of moisture from the sea to the atmosphere, interfere with the transport and deposition of some gases and other aerosols and produce most of the sea-salt aerosols.
As part of the continuing Humidity Exchange Over the Sea (HEXOS) programme, the laboratory oriented subprogramme HEXIST takes advantage of the unique possibilities of the IMST Large Air-Sea Interaction Simulation Tunnel to test some models and parameterizations that can eventually be extended to the open ocean. The emphasis is on the microphysics and turbulent transport processes in the lowest atmospheric layer, and especially:
-
bubble-mediated spray droplet production,
-
aerosol transport by turbulence,
-
droplet evaporation in turbulent humidity field,
-
water vapor flux and turbulent field structure.
The HEXIST programme includes simultaneous developments of numerical models and experimental investigations.
