Summary:The vertical distribution of the wind speed and its standard deviation was measured using a LiDAR wind profiler at two different sites. The first case was to observe the sea-land breeze in the west coast of the middle Taiwan. The wind velocity profile showed that the wind speed decreased with the increase of the height. The thermal effect raised advection between the sea-land boundaries was the mechanism responsible for the formation of the low level jet. The second case was observed a strong wind when typhoon passed in the southern coast of Taiwan. The wind profile showed the increase of the wind speed with the increase of the height. However, the neutral logarithmic profile is unlikely to explain the measured wind speed distribution. A post-calibration of direct comparison of two LiDAR systems showed the very good agreement of 10-minute averaged wind speed and direction.
