The need for active region disconnection in 3D kinematic dynamo simulations

Autor: Whitbread, T., Yeates, A. R., Muñoz-Jaramillo, A.

Publikováno v: A&A 627, A168 (2019)

In this paper we address a discrepancy between the surface flux evolution in a 3D kinematic dynamo model and a 2D surface flux transport model that has been closely calibrated to the real Sun. We demonstrate that the difference is due to the connecti

How many active regions are necessary to predict the solar dipole moment?

Autor: Whitbread, T., Yeates, A. R., Muñoz-Jaramillo, A.

We test recent claims that the polar field at the end of Cycle 23 was weakened by a small number of large, abnormally oriented regions, and investigate what this means for solar cycle prediction. We isolate the contribution of individual regions from

Parameter optimization for surface flux transport models

Autor: Whitbread, T., Yeates, A. R., Muñoz-Jaramillo, A., Petrie, G. J. D.

Publikováno v: A&A 607, A76 (2017)

Accurate prediction of solar activity calls for precise calibration of solar cycle models. Consequently we aim to find optimal parameters for models which describe the physical processes on the solar surface, which in turn act as proxies for what occ
