Study and solution of identification problems for nonstationary 2D and 3D convection–diffusion equations

In this paper we consider two nonstationary heat convection–diffusion models. The first model describes convection–diffusion processes in the 'surface' ocean layer. The second one is a 3D model and describes heat propagation processes in the whole ocean. We pose identification problems for the models and propose methods for solving the problems posed. In the case of the 2D model, the methods of its solution are theoretically justified. Experimental results using real data for the water area of the Indian Ocean are given.
