“…The expression derived with the latter method can be reduced to that derived with the former method under the condition of σ 2 R ≪ 1 [4]. However, several experiments [11][12][13][14] and theoretical investigations [15,16] have exhibited non-Kolmogorov turbulence spectra in certain portions of the atmosphere. The expressions of the irradiance scintillation index, which were developed for moderate-to-strong Kolmogorov turbulence, cannot be directly applied in the moderate-to-strong nonKolmogorov turbulence cases.…”

A new atmospheric spectral model and expressions of irradiance scintillation index are derived theoretically for optical wave propagating through moderate-to-strong non-Kolmogorov turbulence. They are developed under Andrews' assumption that small-scale irradiance fluctuations are modulated by large-scale irradiance fluctuations of the wave, and the geometrical optics approximation is adopted for mathematical development. A wide range of turbulence strength is considered instead of a limited range for weak turbulence. The atmospheric spectral model has a spectral power law value in the range of 3 to 4 instead of the standard power law value of 11/3. Numerical calculations are conducted to analyze the influences of spectral power law and turbulence strength.

“…Other experiments showed that atmospheric turbulence in maritime environments can assume a different statistical behavior with respect to Kolmogorov [7][8][9][10][11][12][13]. In addition, anisotropy in stratospheric turbulent inhomogeneities has been experimentally investigated [14][15][16][17], and laboratory results have shown that turbulence can be anisotropic. These studies cast doubt on the correctness of the conventional assumption of isotropic turbulence through the entire atmosphere.…”

A wealth of experimental data has shown that atmospheric turbulence can be anisotropic; in this case, a Kolmogorov spectrum does not describe well the atmospheric turbulence statistics. In this paper, we show a quantitative analysis of anisotropic turbulence by using a non-Kolmogorov power spectrum with an anisotropic coefficient. The spectrum we use does not include the inner and outer scales, it is valid only inside the inertial subrange, and it has a power-law slope that can be different from a Kolmogorov one. Using this power spectrum, in the weak turbulence condition, we analyze the impact of the power-law variations α on the long-term beam spread and scintillation index for several anisotropic coefficient values ς. We consider only horizontal propagation across the turbulence cells, assuming circular symmetry is maintained on the orthogonal plane to the propagation direction. We conclude that the anisotropic coefficient influences both the long-term beam spread and the scintillation index by the factor ς 2−α .

“…The Kolmogorov power spectrum was mainly used due to its mathematical simplicity [6,7]. However, in some layers of the atmosphere experimental data and theoretical investigations have shown significant deviations from the Kolmogorov model [14][15][16][17], which has prompted research on a more general non-Kolmogorov power spectrum [18]. This power spectrum is seen to have spectral power-law values (exponent) that deviates from the Kolmogorov exponent (11/3) and can assume values between 3 and 4.…”
