Nature of project: data analysis, theory
Available to students on full-time physics degree schemes or joint students.
The magnetic local time and latitude dependence of amplitude of the main impulse (MI) of geomagnetic sudden commencements (SCs) and its seasonal variation have been investigated using geomagnetic data in the latitudinal range 27-70 degrees for the period 1996-2010 over the Japanese longitudes. Is there a longitudinal variation or not? You will first identify SC events and then gather data and statistically analyse the data set.
This area of research delves into the region of the solar-wind-Earth interaction. Knowledge of these events enables us to map the plasma that satellites fly in during the initial phases of geomagnetic events.
A successful project will develop beyond the above in one/some of the following directions:
A 3-D model of one SC event would develop this area further.
When considering where to take your project, please bear in mind the time available. It is preferable to do fewer things well than to try many and not get conclusive results on any of them. However, sometimes it is useful to have a couple of strands of investigation in parallel to work on in case delays occur.
Additional scope or challenge if taken as a Year-4 project: Including another longitude and analysing one event with a forward model would be required of a fourth year student.
Please speak to Heather McCreadie (hem18) if you consider doing this project.
Initial literature for students:
The student will learn to program in Matlab. This will require initial assistance.
