"Air pollution has been notoriously known problem connected with human activities mainly in industrial countries. Solution of this problem has been sought for decades. It has already been proven that this process takes place in the atmospheric boundary layer (ABL) and that it is a very complicated and synergic problem. The methods of mathematical and physical modelling are used in its solution. The physical modelling is based on principles of analogy, especially on analogy of flow in ABL and flow in boundary layer modelled in special wind tunnel that mets dynamical, thermical and geometrical similarity criteria. Even here, there is no universal method and methods of approximate stimulation that solve task classes, are deduced. In case of disaster, accidental gas release or fire accompanied by gas escape, the situation is very complicated. The gas usually releases inside the industrial area, among the buildings or obstacles, often in topographically complicated terrain."@en . . .
