Abstract

In order to achieve a movement rule for contaminative clouds by explosion and deflagration, field experiments were carried out during the summer of 2010 in which the process of the fireball and movement of the clouds were recorded respectively using high speed CCD recorders, video cameras and infrared photography. Based on the assumption that the main effects on the ascending movement of clouds are gravity and buoyancy, we provide a numerical model for the movement of the clouds that considers the meteorological conditions. The modelling results are reasonable compared to the data obtained from the experiment, which can serve as a reference to the related fields.
