The Nuclear Explosion Cloud Evolution Model Based on the Mesoscale Weather Model
A nuclear explosion is a process in which a large amount of energy is released instantly in a finite volume.Various physical effects can be produced during and after a nuclear explosion,spreading far away from the explosion area.The nuclear cloud generated by nuclear explosions can pollute the air and cause large-scale ground contamination.Therefore,it is indispensable to study the motion law of nuclear clouds.This paper mainly studies the formation of nuclear clouds from nuclear explosions.Fire-ball initialization is added to the weather research and forecast model to simulate the evolution process of nuclear explosion smoke clouds with different explosion yields,height and meteorological conditions.In this paper,the vertical and horizontal directions are fully demonstrated,and the change of flow field with time is simulated.The experimental results show that the process of nuclear cloud evolution of the nuclear explosion conforms to the relevant theoretical knowledge,and the experiments are basically desired.Overall,this study provides a basis for improving the capability of nuclear weapons capability and understanding the movement of nuclear cloud.
