1. Dynamo Modeling: What HMI/AIA can do for us (and perhaps vice versa) Mark Miesch HAO/NCAR, JILA/CU (Sacha Brun, Juri Toomre, Matt Browning, Marc DeRosa, Ben Brown) Feb, 2006

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

3. Question 2: Where is the  -effect? How can HMI help? Estimates of flux emergence, diffusion, cancellation

4. Question 3: What maintains the Solar Rotation? How can HMI help? Latudinal entropy/temperature variations Velocity correlations (Reynolds stresses)

5. 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

6. Question 5: What confines the tachocline? How can HMI help? Tachocline oscillations, structure Gough & McIntyre 1998Brun & Zahn 2006

7. Question 6: What is the nature of giant cells? How can HMI help? SSW, N/S downflow lanes, velocity/thermal/magnetic correlations

8. Question 7: How does flux organize, destabilize and emerge? How can HMI help? Structure below active regions: how deep do they go? Courtesy Y. Fan

9. Question 8: How does magnetic helicity flux through the photosphere effect the dynamo? How can HMI help? Estimates of helicity flux, patterns Courtesy S. Gibson
