With winter upon us in full force, outdoor temperatures are plummeting. But inside an intense tornado, it’s always chilly — no matter the time of year. A new study from Concordia proves why that’s the case.
In an article forthcoming in the Journal of Aircraft of the American Institute of Aeronautics and Astronautics, mechanical engineering professor Georgios Vatistas looks into the case of a violent tornado that touched down in 1955 in Scottsbluff, Nebraska.

In an article forthcoming in the Journal of Aircraft of the American Institute of Aeronautics and Astronautics, mechanical engineering professor Georgios Vatistas looks into the case of a violent tornado that touched down in 1955 in Scottsbluff, Nebraska.
During the storm, three broadcasters from the mobile unit of a local radio station were reporting live on the scene and had to take shelter in the basement of a stone building. There, as the tornado’s funnel passed overhead, they reported strange climatic changes. The temperature dropped from a mid-summer average, down to chilly, until the broadcasters were actually cold. They also found it difficult to breathe.
For 61 years, the cause of these phenomena remained unexplained. Enter Vatistas — a leading expert on the topic — who was able to formulate an analytical approach that allowed him to construct a new mathematical model of a turbulent compressible vortex.
