[0093] In cooperation with the World Meteorological Organization, Global Nuclear Safety Consulting conducted two large-scale particle tracer experiments in Europe in 1994. This example takes the simulation of the first European particle tracer experiment as an example. The total amount of air pollutants released is 340kg; The outlet flow rate of pollutants is 7.98g / s; the release point is at 2° east longitude and 48° north latitude; the calculation time step is 1hr; the calculation cut-off time is 120hr; the calculation range is from 10° west longitude to 40° east longitude and north latitude 20°~70°; the recording grid is 0.1°×0.1°; the number of simulated particles is 10 6 The spatial resolution of meteorological data in the calculation is 1.125°×1.125°; the temporal resolution of meteorological data is 6hr.
[0094] In this embodiment, the flow chart of the method for quickly predicting the atmospheric diffusion of air pollutants by using time stacking is shown in figure ...
