The combined effects of acoustic nonlinearity and diffraction on the propagation of intense acoustic waves in an inhomogeneous moving medium are investigated Л nonlinear parabolic equation that accounts for diffraction, nonlinearity, absorption, scalar inhomogeneities (density and sound speed) and vectorial inhomogeneities (flaw) is employed, A 2D numerical algorithm is used to solve the equation and to investigate the propagation of initially harmonic waves in media with random inhomogeneities of different types. The results are compared with those obtained using ray theory (within the paradigm of nonlinear geometrical acoustics) in order to investigate the impact of diffraction on focusing in inhomogeneous media. It is shown that the prediction of caustics and shadow zones by nonlinear geometrical acoustics only partially corresponds to the regions of high and low pressure levels predicted with the nonlinear parabolic wave equation. The discrepancy between the results of the models increases for smaller size of inhomogeneities and for longer distances in randomly inhomogeneous media. When nonlinearity is present distorted waveforms are obtained in the diffraction field even in the shadow zones of decreased pressure due to scattering of higher frequencies from the areas of focusing.
