Tornadoes: mechanism and control.

S A Colgate

    Science (New York, N.Y.)

    Summary
    This summary is machine-generated.

    Electrical energy may power tornadoes, but hydrodynamics limits energy exchange. A high-reaching line sink of heated air, at least 5 km tall, drives the vortex, suggesting potential tornado control mechanisms.

  • A minimum 5-kilometer high line sink of electrically heated air is required to drive the vortex.
  • The electrical heating mechanism offers potential avenues for tornado control.

    • Conclusions:

    • The study elucidates the interplay between electrical energy and hydrodynamics in tornado formation.
    • A specific vertical structure of atmospheric heating is necessary for tornado sustenance.
    • Findings suggest that targeted atmospheric heating could offer a method for mitigating tornado intensity.
