The present classic and quite rare volume is fully addressing the parabolic approximation to a problem of wave diffraction over a sea surface. While the established method of parabolic equation in propagation of the radio waves over the earth surface was first introduced by V. Fok nearly half a century ago, it has been observed that the popularity of subject method has grown quite drastically because of the ongoing development of the new computational methods, and this is done on the basis of the parabolic approximation. This, in turn, resulted in the evolvement and further utilization of the several computational techniques applied to the analysis of propagation of the acoustic waves and radio waves in deterministic and random media. The publication is mainly concerned with the such important problem as the wave propagation over the sea surface in the atmospheric boundary layer and the analytical solution to this problem. The author has covered two basic math methods, depending mainly on the ease of getting the closed analytical solution. However, the publication has not been intended to provide a complete step-by-step background to those mathematical methods; it is rather dedicated to the analysis and application of the different physical mechanisms directly associated with the diffraction, scattering and refraction, and their combined effect...
