The aim of this study is to characterize the phenomenon of a whirlwind and analysis of their appearing in the United States. On a large scale appearing tornadoes were traced in years 1950-2009. Presented are the conditions under which air vortices are formed, a detailed division of their and specific properties. In the examined time it appeared in the USA over 50 thousand of tornadoes. Were registered 148 cases of so-called „tornado outbreak”, in frames which were created almost 7680 air vortices. They showed that tornadoes were appearing mainly in spring (most in May), in the afternoon. They are usually hitting such states as: Kansas, Oklahoma, Missouri, Illinois, and Texas. Cycles of whirlpools most often turn up about lowest intensity at the Fujity scale (F0) which a few more dangerous phenomena usually accompany (F4 or F5). In final years is being registered an increase in the frequency of whirlwinds. Better methods of monitoring these phenomena influence on it. They contribute to the improvement of the system such as warning people against the element. Year after year, this decreasing the balance of victims and people affected by the tornadoes.
