The quasi-two-dimensional model of impurity propagation early designed elsewhere is modified for transporting of allergenic plant pollen from spread forested areas in vicinity of a large city. The model includes consideration of mesoscale hydrothermodynamicalВ  processes in the lower atmosphere taking into accountВ  thermal nonuniformities of the underlying surface in the urban and suburban environs. The boundary conditions and the model coefficients are determined using the parametrization method. Some results of numerical calculations are presented. The calculations were performed using parallelized algorithms on the cluster supercomputer of the Vyatka State University. They show that, due to the action of an inhomogeneous horizontal temperature gradient in the lower atmosphere, vortex flows can be formed above populated areas.

We apply mathematical modeling approach to study mechanisms underlying the robust formation of periodic pattern during the Drosophila eye development. Model is fitted to the preliminary quantitative data – concentrations of the main regulators of R8 cell selection and specification. We analyze how biological noise propagates within the model to explain the molecular mechanisms responsible for noise buffering.
