A simple physics-based method for estimating optical turbulence (2) within the surface layer over snow and ice is proposed, using the Tatarski equation with an improved outer scale model. This improved outer scale model mainly requires the calculation of the wind shear and temperature gradients. Based on the measurements from a mobile polar atmospheric parameter measurement system at the Antarctic Taishan Station in 2014, 2 was estimated using two methods: the Tatarski equation and the Monin-Obukhov similarity (MOS) theory. Compared with 16 days of measurements from a micro-thermometer, the correlation coefficient of (2) estimated by the Tatarski equation is 0.72, which is a slightly more accurate 2 variation in trend and magnitude than the MOS theory. The results suggest that this simple method has potential value for the forecasting applications of optical turbulence.
提出了一种基于简单物理方法,利用带有改进外尺度模型的塔塔尔斯基方程来估算冰雪表面层内的光学湍流(2)。这种改进的外尺度模型主要需要计算风切变和温度梯度。基于2014年南极泰山站移动极地大气参数测量系统的测量数据,使用两种方法估算了(2):塔塔尔斯基方程和莫宁-奥布霍夫相似性(MOS)理论。与微型温度计16天的测量结果相比,塔塔尔斯基方程估算的(2)的相关系数为0.72,在趋势和量级上比MOS理论估算的(2)变化略更准确。结果表明,这种简单方法在光学湍流的预测应用中具有潜在价值。
