In this review, our present day understanding of the Sun's global photospheric and coronal magnetic fields is discussed from both observational and theoretical viewpoints. Firstly, the large-scale properties of photospheric magnetic fields are descri... Read More about The Sun's Global Photospheric and Coronal Magnetic Fields: Observations and Models.

Lagrangian coherent structures in photospheric flows and their implications for coronal magnetic structure (2012)

Aims. We show how the build-up of magnetic gradients in the Sun’s corona may be inferred directly from photospheric velocity data. This enables computation of magnetic connectivity measures such as the squashing factor without recourse to magnetic fi...

Chirality of high-latitude filaments over Solar Cycle 23 (2012)
Journal Article

A non-potential quasi-static evolution model coupling the Sun's photospheric and coronal magnetic fields is applied to the problem of filament chirality at high latitudes. For the first time, we run a continuous 15 year simulation, using bipolar acti... Read More about Chirality of high-latitude filaments over Solar Cycle 23.
