Inner Magnetosphere/Storms: Wednesday, June 23, 10:20 ˆ 12:10 AM, Club Room

Sudden Impulse Propagation through the Magnetosphere

Motivation: The propagation of a simple compression of the magnetopause through the magnetosphere while simple in concept is complicated by the dipolar geometry of the magnetic field, the tensor conductivity of the ionosphere and the multiple MHD modes in which waves travel. Thus we still do not completely understand the signatures that we see in the data, and their relative timing. Sufficient global coverage with high resolution magnetometers now exists that this problem can be addressed.

Pi2 Propagation

Motivation: Understanding the mechanism that initiates substorms requires knowing accurately the relative sequence of events. One of the temporal markers frequently used in substorm research is the generation of Pi2 pulsations, irregular oscillations of the magnetic field with periods of many tens of seconds. The speed of these waves is low with respect to the velocity of many of the particles that are energized in substorms. Thus, unless their propagation can be properly taken into account, they cannot help in distinguishing between mechanisms. In this session we examine what we know about the propagation of Pi2 pulsations and attempt to explain some paradoxical behavior in their arrival times.

Wednesday, June 23, 1:30 - 3.20 PM, Club Room

Motivation: Use of dual station measurements of Pc3 pulsations allows the determination of the location of lines resonating at a particular frequency. The resonant frequency depends on the equatorial mass density and, by monitoring this frequency, one can watch the plasmasphere fill as the daylight hours progress. Perhaps surprisingly, storms affect the plasmasphere to very low L-values and the evolution of these depletions and refillings can also be followed by the resonance monitoring technique. This session reviews the principles behind the technique; examines how best to identify the standing waves; and looks at some of the newest results in this field.

All Discussion and Recommendations

Status and Plans

Motivation: Ground based magnetic records have long played a crucial role in understanding the behavior of the magnetosphere and ionosphere. Our understanding of the magnetosphere has reached a stage where we need timing accuracies of 1 second or better and often sub nT precision. Moreover, it is no longer enough to have single sites, or even chains, but rather two dimensional arrays are needed. Fortunately, it is possible to build such precision instruments relatively inexpensively, and many groups have done so. Yet some regions are not adequately covered. In this session we review the status of operating networks, their data availability, their sampling frequency and future plans. We also welcome the discussion of new networks and where our needs are greatest.

The GEM Substorm Challenge focuses on a single substorm event (November 24, 1996, around 2230 UT) and invites both experimentalists and modelers to analyze and model the event. The primary objective is to assess the models's capabilitiesto reproduce and explain aspects of the event. Of course, a thourough understanding of the event from an experimental pointof view is fundamental for this effort. This is likely to be the last session regarding this challenge. Besides individual presentations we will discuss what we have learned from thischallenge, how we want to publish the results, and where weshould go from here.

The Substorm Observations working group of the GEM Magnetotail/Substorm campaign will discuss observational aspects of substorms in a model-independent way. Our goal is to provide a list of observational constraints that can be placed on modeling/theoretical studies as well as can be used as a guide for future data analyses. The subjects for this year's workshop will be (1) the timing of onset-associated signatures and (2) near-Earth plasmasheet dynamics during the interval around substorm onset. For the latter subject, an emphasis will be placed on the relationship between mid-tail and inner magnetospheric substorm signatures. Relevant ionospheric observations will also be included. Two slots (~1h45m) will be allotted to each subject. One of the substorm timing sessions will be devoted to discussions of ground-based magnetic array studies and how they can be used to elucidate timing and propagation issues. A fifth session is scheduled for discussionand planning of future GEM substorm observation activities. The sessions will be organized in a discussion-oriented way, and we welcome anybody who is working on these subjects to bring viewgraphs and to join the discussion.

Continued discussion of triggering from session I -- is triggering real?

Models of triggering -- Mike Wiltberger

Discussion: What sort of observations/models do we need to settle the question?

or the other?

A critical aspect of understanding magnetospheric substorms is a

determination of the extent to which they are the result of an

internal instability versus being the result of changes in

interplanetary conditions affecting the magnetosphere. During this 2

hour discussion at the 1999 Snowmass workshop, we will hear

evidence on whether substorms are triggered by an internal

instability, an external mechanism, or some combination of both.

Additionally, we would like to discuss approaches to answering these

questions, including - but not limited to - large scale statistical

studies. Our main focus will be on observations of substorms and

their possible triggers or lack thereof. Ideas for how we can proceed

towards a definitive answer to the problem of an internal versus an

external cause for substorms are particulary encouraged, including ways to

allow for the well-know spatial variations in the interplanetary medium

that affect our ability to accurately monitor the interplanetary conditions

affecting the magnetosphere.

Open discussion to follow

The dual issues of the global character and time delay of the ionospheric convection response to changes in the IMF have recently been topics of considerable controversy. In this session, we will examine the different viewpoints, as based upon observations, theoretical arguments, and modeling results.

Presentations in rough order of appearance:

Ray Greenwald: The ionospheric convection response to changes in the IMF from the perspective of the Cowley-Lockwood model.

Aaron Ridley: Examining the rate of change of the ionospheric electric potential as a function of MLT after changes in the IMF

Mike Ruohoniemi: The response of high-latitude convection to a sudden southward IMF turning

David Muir: The ionospheric convection reconfiguration time in response to IMF changes.

Simon Shepherd: A possible explanation for rapid large-scale ionospheric responses to southward turnings of the IMF

Joel Fedder: Fast wave propagation and convection onset from IMF southward turning.

Other Contributions: ?????????

Discussion: How can we resolve these differing viewpoints

However, theoretical ideas for the general problem of electron accelereation will also be discussed and we will need to address how these are related to any specific storm.
