Solar Variability and Atmospheric Couplings in Space Weather Research Program

Input for the next SCOSTEP program includes a focus on solar variability, Earth-affecting solar transients, extreme solar-terrestrial events, global trends in solar activity, and atmospheric couplings. Important issues to address are turbulence in solar-terrestrial phenomena, high-resolution observation and modeling, data assimilation for forecasting, and atmospheric dynamics. Capacity building and informatics play key roles in the program infrastructure. The proposed large-scale projects in 2014-2018 include solar telescope development, ERG satellite launch, maintenance of Hinode operations, database development activities, and radar expansions in Antarctica and equatorial regions. The CAWSES-ISEST Project aims to study Earth-affecting solar transients through the creation of databases, kinematic properties quantification, theoretical modeling, numerical prediction models, and development of prediction tools with a focus on public outreach and education.

  1. Dec 25, 2012 Dec 28, 2012 rev.B Input for next SCOSTEP programafter CAWSES-II Japanese SCOSTEP committee of Science Council of Japan (Chair: Prof. TatsukiOgino, Nagoya Univ.)

  2. Suggested topics for new Task Groups SOLAR VARIABILITY • Earth-affecting solar transients • See appendix 2 • Extreme events in the solar-terrestrial system • Solar maximum and declining phase • 2014-18 will be the maximum and declining phase of solar activity • Discrimination of global trends and solar activity COUPLINGS • Latitudinal coupling in atmosphere and geospace • e.g. energy transfer from high to low latitude during geomagnetic storm • Coupling between equatorial and mid-latitude/polar ionosphere • Atmospheric coupling between different latitudes and hemispheres • Whole atmosphere and geospace coupling • Expansion of TG-4/CAWSES-II to global scale and into geospace • Effect of geospace disturbance to the atmosphere IMPORTANT ISSUES • Turbulence/small scale processes in solar-terrestrial phenomena • A new issue arising from high-resolution observation and modeling • Combination of observation and modeling (in space weather) • Data assimilation for precise forecasting • Atmospheric dynamics for ground-ionosphere electric current INFRASTRUCTURE • Capacity Building • Informatics including big data.

  3. Keywords for the titleof next SCOSTEP program after CAWSES-II • No ‘CAWSES-III’, but the basic concepts of CAWSES should continue. • Climate, Weather, and Impact • Extreme, Severe, Space storm • 5 year project is preferable Help for wording needed from English-speaking members.

  4. (appendix 1) Possible large-scale projects expected in 2014-2018,which Japanese group will organize or join • Solar Telescope (Kyoto Univ.) • ERG satellite for radiation belts (launch: 2015) • Hinode will keep its operation • IUGONET (database development activity) • PANSY radar will be in full operation in Antarctica • EISCAT-3D will be in operation (international collaboration) • Equatorial atmosphere radar is newly proposed. • Multi-point ground network will expand to subauroral latitudes and Asia/Africa • International school activity will be kept by Kyoto Univ. and Kyushu Univ.

  5. (appendix 2) CAWSES-ISEST Project International Study for Earth-Affecting Solar Transients (ISEST) SOC Members: Jie Zhang (USA), B. Vr?nak (Co-Chair, Croatia), A. Asai (Japan), P. Gallagher (Ireland), A. Lara (Mexico), N. Lugaz (USA), C. Mostl (Austria), A. Rouillard (France), N. Srivastav (India), Y. Yermolaev (Russia), Y.-M. Wang (China), D. Webb (USA) An international effort including observations, data analysis , modeling, and transition from science to prediction operation. The ISEST tasks are (1) Create a comprehensive database of Earth-affecting solar and heliospheric transient events (2) Characterize and quantify the kinematic and morphological properties of transient events (3) Develop advanced theoretical models of the propagation and evolution of heliospheric transients (4) Develop advanced 3D numerical models of prediction of ICME arrival and the expected strength of space weather impact (5) Prediction tool development (6) Public outreach and education
