Abstract.

This paper reviews modelling of the ocean thermal skin and investigates
the Saunders (1967) parameterisation of the observed deviation between
the observed radiometric sea surface temperature and the bulk
temperature at 5.5m. The aim is to determine possible regional
meteorological and physical dependencies of the observed lambda
variability with wind speed as found by Donlon (1994). The work of
Payne (1972) on albedo temporal variability is implemented, allowing an
improved estimate of the daily variation in the absorbed downwelling
solar heat flux. Saunders forced convective and free convective
parameterisations are also applied to day time conditions. Results of
this study suggest that the forced convective parameterisation
adequately describes the skin temperature deviation within the
observational error for night and day conditions.  Although specific to
the particular physical and meteorological conditions, these results
therefore have implications for the integration of Saunders forced
convective model into a satellite retrieval algorithm for bulk sea
surface temperature.
