To evaluate the influence to which radon and its decay products cause the thunderstorm activity, a large area diffusion model of radon is constructed for an Australian northern part that is one of the most frequent region of the thunderstorm in the world. The advection and diffusion analysis of radon in the atmosphere was carried out, and it compared it with the measured result of the radon concentration in the region from the dry season to the rainy season.
