    "abstract": "Reaction equations of homogeneously mixed pollutants in the atmosphere can\nlead to non-stationary periodic solutions. It is important to know in which\nrespect these solutions are modified under the influence of the atmospheric\ncurrents. We investigate this question in a very simple model: The reaction\nequations are modeled by the equations of the brusselator and the currents are\nrepresented by an isolated vortex. In the limit of high vortex currents we find\nagain the homogeneous solutions whereas for smaller currents complicated\nspatial and temporal patterns emerge. The role of the diffusion as a singular\nperturbation is investigated.",
