January 23, 2019. Senior researcher of the Ishlinskiy Institute of Problems of Mechanics, RAS, Dr. Sc. V. V. Bulatov made a presentation on “Modern problems of mathematical modeling of the wave dynamics of natural stratified media” at a scientific seminar in the Belousov hall of GC RAS.

The presentation dealt with the fundamental problems of mathematical modeling of the wave dynamics of natural stratified media (ocean, atmosphere). The author presented the basic mathematical models describing the processes of excitation and propagation of internal and surface gravitational waves in stratified vertically, heterogeneous horizontally and non-stationary media and asymptotic methods, which are a generalization of the space-time ray method (geometric optics method, WKB method).
