  • The sunspot cycle is thought to arise from large-scale motions inside the sun: north-south and east-west flows (meridional circulation and torsional oscillation, respectively) and differential rotation in which the solar equator rotates faster than the poles.

  • Using data from the Global Oscillation Network Group (GONG) facility of the National Solar Observatory and from the Stanford University Michelson Doppler Imager (MDI) on NASA's Solar and Heliospheric Observatory (SOHO) spacecraft, we have constructed a map of the torsional-oscillation flow inside the sun over the past 14 years.

  • A certain three-legged cocker spaniel named Tubby found out about torsional waves the hard way: Tubby was the only fatality when the Tacoma Narrows Bridge in Washington state collapsed in 1940, wrecked by torsional (twisting) waves and resonances.
