Originální abstrakt

The aim of this paper is to provide a solution to the atmospheric advection-diffusion equation (ADE) and to describe its properties from the stability and the accuracy point of view. We suggest how to solve the problem by an approximation of the ADE with the system of ordinary differential equations and we state the theoretical limitations of a discretization steps both in time and space. We have done series of tests that prove the theoretical assumptions. The advantage of our approach with respect to other approaches such as strict finite differencing schemes, finite element methods and different kinds of methods of characteristics is knowledge of its theoretical bounds, simplicity and the ease of extensibility.
