SUB: CALL FOR ABSTRACTS in AOGS-2011 Session ST08 on "Atmospheric Coupling Processes in the Sun-Earth System"

Dear Colleagues,

We would like to bring to your attention the session ST08 on "Atmospheric Coupling Processes in the Sun-Earth System" in the 8th AOGS Assembly scheduled to be held at Taipei during 8 - 12 August 2011. Detailed description of the session is given below. Please consider submitting an abstract to this session on your work that relates to any of the coupling processes between various regions in the Sun-Earth domain (namely, solar wind - magnetosphere coupling, magnetosphere-ionosphere coupling, ionosphere-thermosphere coupling, high-to-low-latitude coupling, including vertical coupling processes of terrestrial atmospheres). I expect that there will be lively discussions on the various aspects of coupling processes in the sun-earth domain in this session.

Last date for submission of an abstract is: 15 March 2011. To submit an abstract visit: http://www.asiaoceania.org/

Thank you, -- D. Pallamraju, C. Lin, G. Lu (Conveners)

ST08: Atmospheric Coupling Processes in the Sun-Earth System

Main Convener(s): Dr. Duggirala Pallamraju (Physical Research Laboratory, India), raju@prl.res.in

Co-convener(s) Dr. Charles Lin (National Cheng Kung University, Taiwan), clin@pssc.ncku.edu.tw Dr. Gang Lu (National Center for Atmospheric Research, United States), ganglu@ucar.edu

The Earth’s atmospheric regions are intricately coupled to one another via dynamical, chemical, and electrodynamical processes in addition to the processes that exist due to the solar & interplanetary effects. The coupling and the energy exchange in the Sun-Earth system can be characterized into short-scales (hours to days, e.g., the time scale of space weather), medium-scales (seasonal, annual, etc.), and long-scales (solar cycle). Several new observations in the recent past have revealed a close connection between the dynamical processes in the lower atmosphere with that of the temporal and spatial variability in the thermosphere and the ionosphere, such as the existence of diurnal eastward modes 3 or 4 in the plasma densities being closely associated with the convective structures in the low-altitude atmosphere, stratospheric sudden warming events in high-latitudes showing enhanced features in neutral and ionized parameters in the upper atmosphere at low latitudes, and propagation of waves from high- to low-latitudes, especially during space weather events.

We solicit papers for presentation in this Special Issue on the “Atmospheric Coupling Processes in the Sun-Earth System” that specifically deal with the coupling processes or coupled interactions in the Sun-Earth system. That is, those works that highlight how the variability in one latitude /altitude/ region is coupled with the variability in other location(s)/region(s). These include coupling processes in the lower-upper atmosphere, magnetosphere-ionosphere, high-to-low latitude, Solar-wind / interplanetary medium to the magnetosphere, in addition to neutral – plasma coupling processes. Realizing the importance of these coupling processes global scale observational campaigns have been carried out under the auspices of major international programs such as, the Climate and Weather of the Sun-Earth System (CAWSES) and the International Heliophysical Year (IHY), and several new insights are emerging from these experiments as well. We welcome papers that deal with experiments, observations, modeling, and data analysis that advance our understanding of the coupling processes within the domain of the Sun-Earth system.
