PREFACE

At the 29th Plenary Meeting of COSPAR held at the World Space Congress in Washington, D.C., a workshop on the magnetosheath was convened by Interdisciplinary Scientific Commission D. Topics included studies and simulations of the global interaction, the properties of the plasma and energetic particles in the magnetosheath, the waves and turbulence in the magnetosheath, the processes occurring at the inner edge of the magnetosheath where the shocked solar wind encounters the magnetosphere and chaos and fractal behavior in space plasmas. The presentations consisted of an introductory tutorial, invited reviews, contributed talks and posters. The scientific program was organized with the able assistance of N. U. Crooker, J. G. Luhmann, T. Higuchi, and D. G. Sibeck. The response of the presenters to the editor's appeal for manuscripts has been good and the present volume presents a moderately complete summary of the workshop.

The importance of the magnetosheath is only now being gradually recognized. Terrestrial researchers often relate the properties of the solar wind to processes occurring within the magnetosphere. Seldom do they take into account that these properties are modified crossing the shock and flowing through the magnetosheath to the magnetopause. In particular, the Mach number of the solar wind affects the temperature of the magnetosheath and hence the plasma beta there. Beta in turn is known to control the rate of reconnection as measured by the strength of accelerated flows at the magnetopause. The shock and magnetosheath can also affect waves connected to the magnetosheath through mode coupling and damping. Unfortunately, few researchers have attempted detailed studies of the high beta, non-linear plasma processes of the magnetosheath. It was hoped that this workshop could encourage such activity.

In closing I would like to thank the session chairmen and referees who worked hard at the meeting and afterwards, reviewing these manuscripts, and whose efforts permitted the timely production of this volume: N. U. Crooker, C. Farrugia, D. G. Sibeck and P. Song.

I would like to thank Z. Niemirowicz and his COSPAR staff for once again providing excellent support for the symposium and to thank the local organizers, especially R. Hart, for arranging such an excellent meeting. Finally, I am extremely grateful for the efforts of my own staff at UCLA in particular Lynda Kim and Angela McKnight who assisted with correspondence prior to the meeting and afterward. All this assistance made my job much easier.
