Some Key Aspects of Solar-Terrestrial Coupling

Dr. David Lauben
Electrical Engineering, Stanford University


The nominally well-behaved solar-terrestrial environment in which we live is nonetheless subject to sometimes violent disruptions in response to explosive solar activity, leading to a host of impacts ranging from the more benign aurora borealis to the more catastrophic failure of electric utility power grids and communication satellites.

This talk gives an overview of some key aspects of solar-terrestrial disruptions particularly as they concern human interests, touching on such topics as coronal mass ejections, magnetic storms, auroral electrojet intensification, and so-called "killer electrons," all of which can be expected to increase in frequency as we approach solar max cycle 23 in y2k.
