基于NOAA模式的典型地区大气湍流高度分布

Atmospheric turbulence in typical area based on NOAA model

研究大气传输问题中的大气湍流主要是研究湍流所造成的折射率随机变化规律。大气折射率结构常数Cn2是表示大气光学湍流强度的一个重要参数。主要利用温度脉动探空仪对大气折射率结构常数Cn2在合肥和北京两个典型地区进行了实地探测及计算分析,同时根据两个典型地区相应气象站点常规气象探空资料统计分析数据,通过NOAA模式得到大气湍流高度分布廓线,并与HV模式廓线和实际测量数据进行对比验证分析,为其他不同典型地区大气湍流模式分布特性的研究提供方法验证和参考依据。

Research of atmospheric turbulence is actually investigation of atmospheric refractive index. The atmospheric structure constant of refractive index C n2 is an important parameter of denoting atmospheric turbulence. The atmosphere temperature, pressure and C n2 were measured in Hefei and Beijing, using new micro -thermal meter. And the statistical character of vertical distribution of atmospheric parameter was investigated by analysis of experimental sounding data in different typical area, offering necessary data for atmospheric turbulence model. Using NOAA model, the atmospheric turbulence models in different typical area were obtained on the basis of actual upper air data. Method evidence and valuable reference will be provided for research on atmospheric turbulence model in other typical area.
