Abstract
The paper proposes a method for analyzing the quality of wind fields from hydrodynamic model forecasts for a specific transport model. This is done using the results of measurements in the Kincaid tracer experiment. The method involves adding normalized random fluctuations to the wind fields up to an altitude of 4 km and analyzing the maximum values of wind speed and direction to obtain accurate results for the transport of pollutants. The measurements are taken from a dense network of specialized stations.
