1. Announcement for IAGA Division IV Working Group IV.2 Meeting
   "Turbulence and Shock Waves in the Heliosphere"
---------------------------------------------------------------
From: I. S. Veselovsky (veselov@dec1.npi.msu.su)

IAGA 8th Scientific Assembly, Uppsala, Sweden
IAGA Division IV Working Group WG IV.2 Meeting
"Turbulence and shock waves in the heliosphere"
Monday, August 11, 1997

1. Scientific discussions.
2. Recommendations about the next IAGA  Symposia on  turbulence
   and shock waves in the heliosphere.

Scientific discussions will be focused on the principal aspects
of the turbulence and shocks in the inner and outer heliosphere:
sources, structure and evolution, sinks. Theoretical and computer
models,  experimental  and  observational  works  and  their
intercomparison  can  be  considered. Interdisciplinary links and
applications are very important. Among them are the solar wind heating
and acceleration problem, dynamical processes in the solar wind source
region, in the interaction region with the interstellar medium and
bodies inside the heliosphere: planets, especially Earth, comets etc.
Diagnostic tools include direct measurements in space, interplanetary
scintillations, optical and radio emission, energetic particle
observations, effects in the magnetosphere and ionosphere, geomagnetic
manifestations and others. The list of subjects is not  complete  and
intend only to call your attention to the problems of the Working
Group IV.2.

The working  group  meeting is designed for a more interactive
discussion and will be in addition to the regular symposia of Div. IV,
which include many of the topics mentioned above.

We anticipate to have interesting scientific discussions and
learn about solved problems, open questions,ideas and perspectives
of the theoretical and experimental works. Abstracts of contributions
should be sent by February 28, 1997 to the LOC using the web address
( http://www.irfu.se/iaga_97.html )  and the copy to the WGIV.2 
Chairman ( veselov@dec1.npi.msu.su ).

As a  result  of  these discussions   recommendations  can  be done 
about future symposia at the next IUGG/IAGA General Assembly in 1999.

To  begin  with  the program preparation of the meeting please
reply  at  your   earliest convenience  and send  me  the  enclosed
questionnaire by February 28, 1997.
