Description
Summary:Aerosols play an important role in a variety of processes in the marine boundary layer. They transfer water vapour, heat, and matter through the air-sea interface, interact with the fields of temperature and humidity by evaporation and condensation, and may act as condensation nuclei in the formation of clouds and fog. Therefore, aerosols are also important to larger scale meteorological processes and climatology. In addition, they affect the propagation characteristics of the atmosphere by absorption and scattering. The SeaCluse code describes and quantifies the non-linear interactions between spray droplet concentrations and the scalar fields of water vapour concentration and temperature in the marine atmospheric surface layer over the waves, in open and coastal regions. The code consists of two distinct parts, a 2-D pre-processor computing the air flow structure and droplet trajectories over the waves in the absence of turbulence and evaporation, and a 1-D "main program" computing along the vertical the horizontally averaged budgets of droplet and water vapour concentrations, and sensible heat, including the dynamic and thermodynamic air-droplet interactions.
