Simplified description of small-scale turbulence

The simplified description of the small-scale nonisotropic turbulence in the form of three integro-differential equations system in the one-dimensional pulse space or the system of three differential equations in the partial derivatives in the modified one-dimensional physical space is presented. Three coefficients of the unstable polarized Fourier components of the velocity pulsation constituent disintegration into the Taylor series near the most unstable direction are the unknown functions. The wave vector modulus and time coordinates constitute the independent variables
