摘　　要：本文介绍了近地面大气光学湍流强度估算方法的最新研究进展。采用Bulk法、人工神经网络法、以及极地数值天气预报模式Polar WRF法,对南极泰山站近地面层光学湍流强度(Cn^2)进行估算。三种方法估算的lg(Cn^2)与实测的lg(Cn^2)比对,其均方根误差RMSE分别为0.41、0.29、0.40;相关系数Rxy分别为0.61、0.90、0.67。In this paper,the latest research progress of atmospheric optical turbulence for estimating method in ground layer is introduced.The bulk method,artificial neural network method and polar WRF method are used to estimate the optical turbulence intensity near the surface layer at Taishan station in Antarctica.The root mean square error(RMSE) of the lg(Cn^2) estimated by the three methods are 0.41,0.29 and 0.40 respectively,and the correlation coefficients are 0.61,0.90 and 0.67 respectively.
