A Search of Large Amplitude Waves in Slow Shock in the Distant Tail and an Examination of Wave Turbulence in the Plasma Sheet Boundary Layer
Two fluid simulations predict that switch-off slow shocks should have large amplitude left-hand wave trains downstream of the shock. Recent simulations show that this feature depends on specific plasma parameters, such as Much number and ratio of electron-to-ion temperature. In this study we carefully examine all distant tail crossings using ISEE-3 field and plasma data. We seek large amplitude rotational waves and compare to shock parameters. We also investigate right-hand waves associated with ion beams in the plasma sheet boundary layer. We examine the role of those back-streaming ions from slow shocks in wave generation. Wave mode cascade and parametric decay in these regions also will be studied.

Global Ionospheric TEC Perturbations Monitored by the GPS Global Network During Two Northern Hemisphere Winter Storms
The global evolution of two major ionospheric storms, occurring on November 4, 1993 and November 26, 1994, respectively, is studied using measurements of total electron content (TEC) obtained from a worldwide network of ground-based GPS receivers.

Global Ionospheric TEC Variations During January 10, 1997 Storm
The ionospheric storm evolution process was monitored during the January 10, 1997 magnetic cloud event, through measurements of the inonospheric total electron content (TEC) from 150 GPS stations. The first significant response of the inonospheric TEC to the geomagnetic storm was at 0300 UT as an auroral/subauroral enhancement around the Alaskan evening sector.

A Pair of Forward and Reverse Slow-Mode Shocks Detected by Ulysses at ~5AU
We report the first finding of a pair of forward and reverse slow-mode shocks in the distant heliosphere using plasma and magnetic field data from the Ulysses spacecraft located at 5.3 AU and 9 degrees South heliolatitude.

A Review of Discontinuities (and Alfven Waves) in Interplanetary Space: Ulysses Results
The Ulysses mission explored for the first time our heliosphere at all latitudes up to +/-80 and therefore has been an ideal mission to study potential gradients in heliolatitude of discontinuity occurrence rates and types.

Distant Tail Behavior During High Speed Solar Wind Streams and Magnetic Storms
We have examined the ISEE 3 distant tail data during three intense magnetic storms and have identified the tail response to high-speed solar wind streams, interplanetary magnetic clouds, and near-Earth storms.

Interplanetary Discontinuities and Alfven Waves at High Heliographic Latitudes, Ulysses
This paper presents results from the first statistical study of interplanetary directional discontinuities at high heliographic latitudes. Ulysses data showed that the rate of occurrence of interplanetary discontinuities (ROIDs) increased dramatically from the ecliptic plane to high (-80 degrees) heliographic latitudes. The high speed streams included Alfven waves.
