Abstract

We modelled a whirlwind in the atmosphere with the aid of system of the linear [1] and weakly nonlinear 3D system of the Navier-Stokes equations. We investigated Gaussian beam propagation through the modelled whirlwind in the atmosphere. Parabolic equation method has been applied for study of the intensity variations of the beam. We investigated the evolution of the whirlwind velocity field and laser beam propagation through it. The examples of the distorted laser beam are presented as the images in 2D plane. A new method was set forth to the compensation of random distortions. The method was applied for compensation of distortions of a laser beam propagating through the whirlwind in atmosphere. Results may be applied for the compensation distortions of images from modern optical telescopes, in targeting problem and even for control of laser beam focusing on object-target in the case of the random turbulent medium.
