摘要光学湍流的强弱和分布是描述天文台址优劣的重要参数．介绍了利用大气模式WRF（Weather Researchand Forecasting Model）计算高美古站周围大气光学湍流参数的方法，这些参数包括cn^2（大气光学湍流强度）廓线、大气相干长度、大气相干时间、视宁度、等晕角和闪烁率等．包括模型计算方法的实现过程、模型的设置和模拟结果的验证．计算结果与云南高美古观测站DIMM（Differential Image Motion Monitor）的实测数据进行了对比．

英文摘要：

The optical turbulence is a key parameter to evaluate an observing station. The methods to obtain atmospheric optical turbulence parameters, including the C2 profile, coherent length, coherent time, seeing, isoplanatic angle, and scintillation index by using meteorological parameters are presented. The accomplishment of this method, configurations of the WRF model （Weather Research and Forecasting Model）, and verification of results are introduced. The reliability is confirmed preliminarily by comparing the results with the DIMM （Differential Image Motion Monitor） measurements.
