ABSTRACT:
A method of reducing the destructive effects of a tornado, which has a rotary motion about a center and has at least one clear air inflow region at its periphery, comprises towing through the inflow region one or more fluid dynamic converters which impart a rotary motion to a column of air and thereby disturb the balance of the rotary motion of the tornado so as to reduce its intensity. The fluid dynamic converter comprises a cylindrical casing which is towed in a lengthwise direction by an airplane and has inside the casing a screw-like vane which imparts a rotary motion to the airstream flowing through the casing.
