Estimating the profiles of atmospheric turbulence above Korla, Maoming, Lhasa by Thorpe scale

  • 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。
