Optimization Problem of Inter-wave Transformations in Geophysics

The optimization problem of inter-wave transformations in adjacent geophysical media is considered in connection with the analysis of the phenomenon of acoustic-seismic conversion. It concerns the transformation of an atmospheric acoustic wave into a surface seismic wave. To characterize the transformation effect, a quantitative factor in the form of an energy criterion proposed. In this case, the problem of optimizing the inter-wave transformation is reduced to finding conditions that maximize criterion. There is a number of limiting factors that can neutralize the effect of acousto-seismic transformation. In as significantly weaken the effect for acoustic-seismic transformation screening effect of the snow cover in the article is discussed. Mathematical simulation of the elastic waves propagation from infralow frequency source taking into account snow cover is considered. The programs for calculation of the acoustic levels through mathematical model based on the conservation laws and differential equations for porous snow medium are implemented. The results of the processing and analysis of the experimental data taking into account the snow cover is executed.
