Nature of project: data analysis, software
Available to students on full-time physics degree schemes or joint students.
The aim of this study is to determine if geomagnetic substorms vary in intensity when they occur in and out of sequence with geomagnetic storms. An investigation into how storms and substorms occur and what differs between them must take place to better understand the phenomena.
The Dst and AE indices for geomagnetic storms and substorms will be used where the data can be plotted graphically in Matlab. The substorms in each phase will then be compared and conclusions drawn.
A successful project will develop beyond the above in one/some of the following directions:
A forward model determining when a storm will occur using substorm data will 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: This is suitable for a student going to Svalbard.
This project is suitable for a year 4 project because two indices rather than one will be chosen. The student will obtain an understanding of two parts of the magnetosphere ionosphere system and their interaction with the solar wind.
Please speak to Heather McCreadie (hem18) if you consider doing this project.
Initial literature for students:
Initial discussion on the elements involved in determining AE and Dst indices and physics behind them will ensue. MatLab discussions will take place.
