Mesoscale Meteorological ModelBased on Radioactive Explosion Cloud Simulation

In order to simulate nuclear explosion and dirty bomb radioactive cloud movement and concentration distribution, mesoscale meteorological model RAMS was used. Particles-size, size-active distribution and gravitational fallout in the cloud were considered. The results show that the model can simulate the ‘mushroom’ clouds of explosion. Three-dimension fluid field and radioactive concentration field were received.
