Onsets and Flapping Studied Using a Dynamic Harris Sheet Model
We have developed a nonlinear fitting routine for the Harris current sheet based on magnetic data, and applied it to 71 plasma sheet crossings by Cluster. In most cases this simple fit appeared to represent the magnetic ...
Automated Regional Modelling (ARM) for characterization of the substorm current wedge
Some characteristics of substorms may be determined through use of an electrojet forward modelling approach. These include the amplitude of cross-meridian electric current (0.2 to 1 MA typically), timescales (about 20 ...
