A meso-γ-scale observational analysis of the fine surface structure of the sea-breeze fronts (SBF) over the coast of southern Israel is presented. Objective criteria for the SBF passage are derived based on wind speed and direction, temperature, and humidity. A realization of an automized detection system for SBF is described. Preliminary results indicate that, in addition to the primary SBF, there are significant and consistent pre- and post-SBF lines. The surface structures of these lines are shown, and related to earlier theoretical studies of the SBF forerunners and Kelvin-Helmholz waves. Although the pre- and post-SBF lines seem to be important for pollutant transport, human comfort, and better theoretical understanding of the SBF, they have previously attracted little attention in the SBF literature.
