  1. CAWSES space weather meeting, 11-12 Sep 2004, Beijing Introduction to this meeting K. Shibata Kwasan Observatory Kyoto Unversity

  2. contents • What is CAWSES ?(based on Dr. Basu’ppt in Sapporo 2003 and in Paris 2004) • Space weather research:from solar physics point of view (based on Shibata’s ppt in Sapporo 2003)

  3. CAWSES: Climate and Weather of the Sun-Earth System Sunanda Basu Chair, CAWSES Science Steering Committee Presented by M. Geller CAWSES Bureau and General Meeting Sapporo, 12 and 13 July 2003

  4. CAWSESClimate and Weather of the Sun-Earth System The New SCOSTEP Program for 2004-2008 Composite picture created at NOAA-NGDC by Dr. Peter Sloss from SKYLAB solar X-ray telescope picture by Naval Research Laboratory and bathymetry and topography databases archived at NGDC.

  5. Strategy • Collect data records to document with increasing fidelity various aspects of the Sun-Earth system. • Use physically based models for assimilating observed data and deriving enhanced outputs for segments of the solar-terrestrial system. • Mobilize SCOSTEP researchers to work together to understand variability throughout the entire solar-terrestrial system.

  6. CAWSES Meetings - Past & Future • First CAWSES SSG Meeting held at Maastricht, The Netherlands on August 24-25, 2002 • Four themes approved by SCOSTEP Bureau at Rio de Janeiro, Brazil, Sept 28-30, 2002 • Theme leaders presented their plans at a Town Hall Meeting on April 8, 2003 during the EGS/AGU Joint Assembly in Nice, France • A special CAWSES Meeting was held on July 5, 2003 in conjunction with the IUGG Meeting at Sapporo, Japan • Membership of the thematic groups was considered at the Sapporo Meeting • Election of new SCOSTEP Executives and presentation of CAWSES Reports at Sapporo on July 12 and 13.

  7. Four Themes under CAWSES • Solar Influence on Climate • Space Weather: Science and Applications Atmospheric Coupling Processes • Climatology of the Sun-Earth System

  8. 2. Space Weather: Science and ApplicationsCo-Chair- Janet Kozyra, U. of Michigan, USACo-Chair - K. Shibata, Kyoto University, Japan • Proposed campaign framework that views the “whole earth as an instrument” for making key space weather observations. CAWSES could: • Recruit and coordinate needed observing sites • Identify and collaborate with major programs worldwide (Spaceship Earth, Intermagnet, GEDAS, CNOFS, etc.) • Set up website and needed technology in collaboration with other programs like ILWS, eGY, etc. • Organize world-wide analysis campaigns on particular themes or for selected events (from NICE Mtg.)

  9. 2. Space Weather: Science and Applications • Impacts on space technology and operations • Effects on humans in space • Telecommunications interruptions • Vulnerability of Earth-surface systems • Navigation upsets • Effects on high-altitude aircraft passengers and crew • Model development through quantitative understanding of multi-scale coupling in the Sun-Earth system (from NICE Mtg.)

  10. 2. Space Weather: Science and ApplicationsPotential Worldwide Campaigns • Predictive Models of the Space Environment • Post event analysis to test predictive models • Analysis of physical processes that occurred & reasons predictions succeeded or failed • Test research models against operational predictions • Document Actual Effects on Life & Society for Events • Power grid loading • Satellite anomalies • Communications problems • Sun-to-Earth Analysis Campaigns for Selected Events • Coordinate CAWSES worldwide maps with other satellite and ground-based data to create global view of events • Coordinate efforts of worldwide research community to analyze and interpret comprehensive data sets • Apply new knowledge of complex system to understanding & predicting space weather effects on society (from NICE Mtg)

  13. Perspectives on CAWSES • CAWSES is an ambitious program that builds on and leverages the broad SCOSTEP programs STEP and S-RAMP and more specialized Post-STEP programs. • CAWSES is particularly timely. • Successful implementation of CAWSES will provide an integrated scientific framework for solar-terrestrial research in the future, and provide an informed basis for guiding later programs under different solar conditions and changing anthropogenic influences and as made necessary by new human institutions and technological advances.

  21. Contents • Solar physics and space weather • Science issue • Future strategy • Meeting • International collaboration • Ground-based observations • Space observations • Numerical simulations

  22. Solar physics and space weather • Traditionally, solar physicists have not been interested in space weather. And, still now. • This is very bad. • One of the important purposes of our activity is to encourage closer communication between solar physicists and geophysicists.

  23. Why solar physicists are notinterested in space weather ?

  24. The “distance” between the Sun and the Earth became much shorter in these 10 years • Common physical proccesses began to be discussed by two communities • Magnetic reconnection • Particle acceleration • …. • Observations of CME significantly developed so that we can now discuss the Sun, solar wind, magnetosphere, and atmospheric phenomena with almost continuos data.

  25. solar corona observed by Yohkoh • Soft X-ray （~1 keV) 2MK-10MK

  26. Magnetic reconnectionin solar flares

  30. One good exmaple • A giant arcade on April 14, １９９４ • K. Shibata reported this arcade event in Yokoh gbo email, suggesting gigantic mass ejections • A. McAllister read the gbo email and realized the possibility of a big magnetospheric substorm, and informed it to the electric power company of Chicato • The company prepared by removing big transformer (~ 5 - 10 M$) • Two days later, actually a big substorm occurred, but the transformer was safe ! • The company thanked US government, US government thanked NASA, NASA thanked Yohkoh team, Yohkoh team thanked me.

  31. Important subjects in solar physics • Triggering and energy storage mechanisms of solar flares and coronal mass ejectons • Coronal heating mechanism • Solar wind acceleration mechanism • Origin of magnetic field (dynamo) • Origin of solar luminosity variation all are important subjects for space weather research
