How is meridional flow related to the Sun’s magnetic dynamo, the sunspot cycle, and the Maunder butterfly diagram?

To determine

Is Meridional flow related to the Sun’s magnetic dynamo; the sunspot cycle; and the Maunder butterfly diagram.

Explanation of Solution

Meridional flow is the improvement of Babcock model. The very slow movement of currents of gas from the equator to the pole region of sun and it travels return to the center of the sun. This flow is called Meridional flow.

Basically the magnetic field of the sun is stronger in the active regions. During this Meridional flow, a group of magnetic field lines are shipped from the active regions to the pole regions and these regions are located at lower latitudes.

Maunder butterfly diagram shows that the change of location of the sunspot in the time of cycle...
