Vertical wind speed profiles near the coast were observed using a Doppler Light Detection and Ranging (LIDAR) system at the Hazaki Oceanographical Research Station (HORS) from September 17 to 26, 2013. In order to investigate the impact of atmospheric stability, wind profiles observed at HORS were compared with a log profile model (theoretical wind profile model), which did not consider atmospheric stability. The wind shear was smaller in the observed profiles when the wind came from sea to land, and larger when it came from land to sea. It was also found that the wind profiles included an obvious diurnal cycle when the wind came from land to sea. The results for this study indicate that atmospheric stability is a significant factor when determining the coastal wind profiles, not only when the wind comes from sea sectors, but also from land sectors.
