摘要:

分析了闽西地区近地面部分高度的折射率结构常数在部分月份的变化特点,结果表明:该地区的近地面折射率结构常数日变化具有较明显的局地特征;白天近地面折射率结构常数高度分布特点符合“-2/5”规律,夜间近地面折射率结构常数高度分布特点符合“-1/3”规律;在10~12月中,由于云量的影响,11月的湍流强度最弱,10月湍流强度最强;同高度条件下,晴天的折射率结构常数约是阴天的折射率结构常数2倍以上。在此基础上,分析了一定条件下该测量区域的湍流因素对激光工程的影响。

Abstract:

The statistical methods are used to analyze the data of refractive index structure parameter of surface layer in October, November and December in a mountainous area of west Fujian Province.The results show that the daily variations of refractive index structure parameter of surface layer in the area have obvious local area characteristics. The turbulence strength of November is weaker than that of October or December. The behavior of refractive index structure parameter in daytime decreases with the height increase and agrees with “-2/5” rule. The behavior of refractive index structure parameter at night decreases with the height increase and agrees with “-1/3” rule. The turbulence strength of October is the strongest in the three months. On the condition of same heights, the refractive index structure parameter in sunny day is about two times than the refractive index structure parameter in cloudy. In the end, the effects of atmospheric turbulence of surface layer on laser engineering on the condition of ceterain assumptions are provided.

Key words: atmospheric turbulence, refractive index structure parameter, daily variation, monthly variation, laser engineering
