摘要

摘要: 在新疆库尔勒、广东茂名海边、西藏拉萨三个地区释放的探空气球, 实现了温度、气压、风速等常规气象参数以及大气折射率结构常数的廓线测量。基于Tatarski湍流参数化方案以及以上地区探空数据, 利用Thorpe尺度估算了新疆库尔勒、广东茂名海边、西藏拉萨三个地区的高空大气光学湍流廓线, 并将这三个地区实测的廓线与其对应的估算结果做了对比, 结果表明: 估算值与实测值在量级和变化趋势上表现出较好的一致性, 相关性分别为69%, 60%, 68%;Thorpe尺度相较于其他估算湍流廓线的参数化方法输入参数少、更简便。

Abstract: The sounding balloons released from Korla, Maoming, Guangdong and Lhasa, Tibet, have been used to measure the profiles of temperature, air pressure and wind velocity and the refractive index structure constants of the atmosphere.Based on the optical turbulence parameterization of Tatarski theory and the above-mentioned areas sounding data, the atmospheric optical turbulence profiles in three regions, Korla, Xinjiang the coast of Maoming, Guangdong and Lhasa, Tibet, are estimated by using Thorpe scale.Estimated results are compared with measured profiles in these three regions.The estimated values and the measured values are in good agreement with each other in the order of magnitude and the trend of change, and the correlation are69%, 60%, 68%, respectively.In addition, compared with other parameterized methods for estimating turbulence profiles, the Thorpe scale is simple and has less input parameters.
