Description
It is well known that tornadoes are visualized by funnel clouds and flying debris. If the relationships among the size and strength of tornadoes, the shape and size of funnel clouds and behaviors of flying debris become clear, it may be possible to evaluate the size and strength of a tornado directly from photos and videos. Therefore, funnel clouds and debris clouds formed in tornado-like flow generated by LES were investigated in this study. As the result of this study, the height of funnel clouds is controlled by the strength of the tornado; the width of funnel clouds is controlled by the humidity and the pattern of flying debris were controlled by Tachikawa number and swirl ratio.
