Influence of incident flow conditions to tornado-like flow was investigated. In order to study the tornado resistance design for structures, it is necessary to reveal flow field of tornadoes. Because it was very difficult to evaluate tornado winds generated in real scale, a tornado simulator was developed in the laboratory and tornado-like flow was measured. The situation in which the form of the tornado-like flow changed depending on swirl ratio and surface roughness was reproduced, and the distribution of wind speeds according to this form became clear. These experiment results showed agreement with similar previous experiment results.
