Findings

Turbulent magnetic pumping significantly influences dynamo operation.

Meridional flow circulation impacts the solar cycle modeling.

Proposed solutions improve understanding of solar magnetic field generation.

Abstract

The sunspot solar cycle has been usually explained as the result of a dynamo process operating in the sun. This is a classical problem in Astrophysics that until the present is not fully solved. Here we discuss current problems and limitations with the solar dynamo modeling and their possible solutions using a kinematic dynamo model within the Babcock-Leighton approximation as a tool. In particular, we discuss the importance of the turbulent magnetic pumping versus the meridional flow circulation in the dynamo operation.
