| 英文摘要 | Based on the measured thermal radiosondes, the WR95 method is used to identify the vertical structure oflow clouds. The atmospheric refractive index structure constant, meteorological conditions and atmosphericstability are contrastively analyzed under cloudy and clear sky weather. The results show that the influence oflow-level thin clouds on the fluctuation of is negligible, showing only a slight increase trend. The at low-level thin clouds base and top is about 1.6 and 2.5 times that under clear sky weather to a greatest extent,respectively. The at the low-level medium-thick clouds top is 3.8-6.61 times the amplitude of that underclear sky weather, and enhanced amplitude of near the cloud top is greater than that near the cloud base.Atmospheric turbulence near the cloud base is driven by the combined effect of ground heat and low cloudscooling. The sinking airflow from clouds is coupled with the upward airflow from ground, which motivates windshear, resulting increases near this height. A comprehensive comparison of the between clear sky andcloudy weather shows that the enhancement effect of clouds on is roughly on the order of 10-16. Wind shearreaches its maximum value at or above the cloud top. Because of the combined effect of short-wave radiationwarming and long-wave radiation cooling near the cloud top, temperature inversion layers with differentthickness will be formed obove the cloud top, resulting in a sharp increase in the potential temperature lapserate at the cloud top, and the Brunt-Vaisala frequency is increased by 0.5-3.0 times. And near thecloud base is less than that under the clear sky weather. Owing to the turbulent effect caused by cloud multi-scale activities, it is inevitable to cause assessment and correction deviations in the laser transmission. A deepunderstanding of how turbulence behave within different phase clouds or around cloud boundaries can also laythe foundation for further modeling the atmospheric turbulence around clouds |
