【摘要】By virtue of polynomial theory, the near-ground atmospheric turbulence was simulated, which was compared with the near-ground atmospheric turbulence measured by the two-point theory based on temperature fluctuation principle in experimental field. Firstly, the work could take full advantage of the measured meteorological parameters at the experimental site such as temperature, humidity and pressure to carry through the simulation experiment, which provided advantage for the research work. Secondly, practical scientific results could be obtained by the work. In this paper, it focused on the research of correlation between measured turbulence and simulated turbulence by the polynomial theory on condition of relatively high humidity and related changes after refitting polynomial coefficients, and the uncertainty of near-ground atmospheric turbulence measured by the two-point theory was studied. The results show that a strong correlation exists between near-ground atmospheric turbulence simulated by the polynomial theory with near-ground atmospheric turbulence measured by the two-point theory on condition of relatively high humidit. And both can maintain a high stability. But when the relative humidity arrives
