Outline of Final Research Achievements

An onshore and offshore measurement campaign was conducted with two vertical LiDARs (Light Detection and Ranging) at HORS (Hazaki Oceanographical Research Station). As a result, fetch effect which is a wind speed increasing phenomena while traveling over the sea was observed. Horizontally, the fetch effect was obvious within 2 km fetch length and vertically, the effect was also obvious up to 150 m height from the surface. In addition, a comparison of the observation with the simulation using a mesoscale meteorological model showed that the fetch effect clearly shown in the LiDAR observation became rather ambiguous in a numerical simulation.
