[43.01] Solar Torsional Oscillations and the Extended Solar Cycle

R. C. Altrock (AF Res. Lab.), R. Howe (Nat'l Solar Obs.)

Torsional Oscillations were first observed on the surface of the sun as waves of small deviations from differential rotation, which propagate from the pole to the equator over solar-cycle time scales. More recently they have been inferred from observations of solar global oscillations to occur in the convection zone. Other solar phenomena, such as ephemeral regions and brightenings in the corona, have also been observed to propagate from near the poles to the equator over similar time scales. These other phenomena have been collectively referred to as the "Extended Solar Cycle". This paper will discuss the relationship between torsional oscillations as observed in the convection zone and the "Extended Solar Cycle" as observed in the corona.
