- Аннотация: A new conditionally Eulerian-Lagrangian numerical method is developed to solve a number of problems in which the object of study is concentrated in a region of changing configuration, and the movement within the region is described by a system of equations of a two-dimensional continuous medium. A modification of the computational scheme of particles in cells on adaptive Euler grids is presented on the example of solving the problem of the dynamics of an intrathermocline vortex lens (ITL). The basic equations are equations of the shallow water type. The area in which the fields of the lens parameters are determined is the desired one and is determined in the course of the solution. The artificial viscosity of the numerical scheme is studied, and the results of testing the method and examples of computational experiments are presented.
