Abstract

As was discussed in the previous chapters as well as in Chapter 11, marine aerosols play an important role for climatic, meteorological and chemical models. Such models require accurate representation of aerosol fluxes from the sea surface to the atmosphere and from the atmosphere to the ocean. In modelling aerosol generation and aerosol impact on the climate, two types of approach, namely the diagnostic approach and the seasonal or synoptic scale approach, can be distinguished. In the diagnostic approach we look for marine aerosol fluxes at a given location and at a given time, while in the seasonal or synoptic scale approach we seek to predict aerosol flux variation in the scale of months or seasons for a given sea basin. In general, aerosol fluxes are complex functions of wind speed, wind history, atmospheric stability and sea surface state. The sea state is represented by surface wave statistics, surface wave spectra, intensity of wave breaking and possibly other parameters such as ocean temperature and surface active substances. However, many present representations of sea spray generation functions use only wind speed as the governing parameter. It should be stressed that a description of the sea surface state as a function of wind speed only is highly insufficient. At a given wind speed, sea surface statistical characteristics and wave spectra can be quite different as wave generation mechanisms involve many other parameters, not only wind speed. For more information on wave generation processes, the reader should refer to books by Phillips (1977) and Massel (1996a).
