Question 1:Are Flux-transport dynamos on the right track?
How can HMI help? Meridional Circulation measurements!

Question 2:Where is the -effect?
How can HMI help? Estimates of flux emergence, diffusion, cancellation
Question 3:What maintains the Solar Rotation?
How can HMI help? Latudinal entropy/temperature variationsVelocity correlations (Reynolds stresses)
Question 4:Are magneto-shear instabilities operating in the tachocline?
How can HMI help? Non-axisymmetric patterns in flux emergence (esp. m=1)
Zonal jets
Question 5:What confines the tachocline?
How can HMI help? Tachocline oscillations, structure
Gough & McIntyre 1998 Brun & Zahn 2006
Question 6:What is the nature of giant cells?
How can HMI help? SSW, N/S downflow lanes, velocity/thermal/magnetic correlations
Question 7:How does flux organize, destabilize and emerge?
How can HMI help? Structure below active regions: how deep do they go?
