The complexity of valley airflow make the observation of low-level wind profiles and related vertical velocity more important, for the study of mountain cloud-fog physics and the technical guidance of weather modification operation. Based on the valley terrain cloud and fog experiment station (CFS) of Mt. Lu and the height difference between CFS and the meteorological station of Mt. Lu (LS), wind profile observations by a Doppler wind lidar at CFS were operated from November to December 2019. The measurements indicated that there was a good correlation between the 80-m wind speed and direction of CFS and the 10-m wind of LS. The 80-m vertical velocity and horizontal wind speed at the CFS site were mainly between ±0.5ms-1 and 2-4 ms-1, respectively. The average wind speed at the CFS site increased with height, with the wind speed in daytime being lower than that in nighttime. The difference in wind speed between day and night increased with height, with a wind speed difference of -1 ms-1 (-0.2 ms-1) at the height of 80 m (40 m). The vertical movement was mainly related to the direction of the airflow, and the vertical velocity was proportional to the horizontal wind speed. The 80-m southerly wind (112.5o-247.5o) at the CFS site was dominated by upward airflow, while the other wind directions were dominated by downward airflow; and this relationship was extended to 260m from 80m. The weak wind shear of low-level airflow at the CFS site can lead to vertical motion stratification, indicating more complexity of airflow in the mountainous terrain than that of the plain.
