Article
Full-text available
It is well documented that space weather can impact electricity infrastructure, and several incidents have been observed in recent decades and directly linked to large geomagnetic storms (e.g., the Hydro Québec incident in 1989). However, less is understood about the impact of lower‐level geomagnetically induced currents on the health of transforme...

The fragmentation of habitat has occurred throughout the history of life on Earth, but has been accelerated and magnified in scale over the past few centuries as a result of human industrial development. Habitat fragmentation affects the welfare of some wild animals directly, through the often violent processes that bring about fragmentation and by...

Diagnosing the solar atmospheric plasma is one of the major challenges in solar physics. Magnetohydrodynamic (MHD) waves, by means of applying the powerful concept of solar magneto-seismology (SMS), provide a tool to obtain diagnostic insight into the magnetized solar plasma in MHD waveguides. This paper provides a road-map of simple but applicable...

Full-text available
We present the first application of a magneto-seismology technique using the MHD theory of asymmetric waveguides. By applying the recently developed Amplitude Ratio Method to chromospheric fibrils, we are able to estimate the local Alfven speed, which has previously been nearly impossible to determine given the observational challenges to directly...
Article
Full-text available
Solar magnetoseismology is an indirect method to approximate plasma parameters that are traditionally difficult to measure in the solar atmosphere using observations of magnetohydrodynamic waves. A magnetic slab can act as waveguide for magnetoacoustic waves that approximates magnetic structures in the solar atmosphere. The asymmetry of the slab ca...

Full-text available
Modeling the behavior of magnetohydrodynamic waves in a range of magnetic geometries mimicking solar atmospheric waveguides, from photospheric flux tubes to coronal loops, can offer a valuable contribution to the field of solar magneto-seismology. The present study uses an analytical approach to derive the dispersion relation for magneto-acoustic w...
Article
Full-text available
Analytical models of solar atmospheric magnetic structures have been crucial for our understanding of magnetohydrodynamic (MHD) wave behaviour and in the development of the field of solar magneto-seismology. Here, an analytical approach is used to derive the dispersion relation for MHD waves in a magnetic slab of homogeneous plasma enclosed on its...
Article
Full-text available
The high insolation during the Southern Hemisphere summer leads to the development of a heat low over north-west Australia, which is a significant feature of the monsoon circulation. It is therefore important that General Circulation Models (GCMs) are able to represent this feature well in order to adequately represent the Australian Monsoon. Given...

We aim to develop novel techniques for solar magneto-seismology that use the spatial signatures of eigenfunctions of asymmetric magnetic structures in the solar atmosphere. Applications include approximating the local solar magnetic field strength in, for example, elongated magnetic bright points, prominences, and sunspot light bridges.
