Abstract The mean structure within the internal boundary layer (IBL) near the shore, which develop from the coast in the presence of a sea breeze, has been described in Part I of this study (Ogawa and Ohara, 1984). This paper presents the results of the similarity and energy budget analysis for the purpose of parameterization of the turbulent structure within the IBL. The analysis of the turbulent kinetic energy balance, turbulent intensities and spectra show that the wind is strongly affected by mechanical turbulence in comparison with the past results in a fully developed convective layer where thermal convection dominated. The standard deviations of the wind velocities normalized by the friction velocity u * (surface-layer scaling parameter) are functions only of the normalized height z/Z i within 160 m of the shoreline, where Z i is the IBL. On the other hand, the standard deviations of temperature normalized by θ* (mixing-layer scaling parameter) have less scatter with distance than those normalized by T * (surface-layer scaling parameter). The data showed that both u * (not a mixed-layer parameter), and Z i (not a surface-layer parameter) are necessary to describe the turbulent characteristics of the IBL near the shore.
