Abstract:
Using a numerical mesoscale model of the atmospheric boundary layer the dynamics of air streams in the Norilsk valley is investigated. Results of calculations for typical weather conditions are presented. It is shown that the orographic peculiarities of the region form a wind field, nonhomogeneous in the horizontal and highly variable in the vertical. With data on pollution of the snow cover in vicinity of the Norilsk copper plant a numerical reconstruction of fields of dust and heavy metals sedimentation is carried out.
Keywords:
atmosphere, snow cover, pollution, numerical modeling, reconstruction
