Sodar observations of coastal boundary layer of three regions are analyzed to examine evolution characteristics of internal thermal boundary layer, land-sea breeze circulation Besides characterizing turbulent mixing processes such as onset, dissipation, depth of sea/land breeze circulations of interest for environment impact assessment, new observations of thin oscillating elevated layers of low frequency have been observed in lower atmospheric boundary layer in coastal region of Arabian sea, Indian ocean and also at the Antarctica ocean. Wavy periods of about 24 hours and residence time of few days are seen. Observations need further planned investigations through multi probing techniques. 1.
